1. THE BOEING 767

1.1. Specs

The Boeing 767 family is a complete family of airplanes providing maximum market versatility in the 200- to 300-seat market. The Boeing 767 family includes three passenger models -- the 767-200ER, 767-300ER and 767-400ER -- and a freighter, which is based on the 767-300ER fuselage.

The twin-engine 767 -- sized between the single-aisle 757 and the larger, twin-aisle 777 -- has built a reputation among airlines for its profitability and comfort.

The Boeing 767 family is a complete family of airplanes providing maximum market versatility in the 200- to 300-seat market. It includes four models:

767-200ER (extended range), 767-300ER -- approximately 10 feet (3.1 m) longer than the 767-200ER, 767-400ER -- approximately 11 feet (3.4 m) longer than the 767-300ER,

and a freighter based on the 767-300ER fuselage.

CabinWidth: The Boeing 767s cabin is more than 4 feet (1.2 m) wider than single-aisle jetliners, and the 767s versatile design allows customers to select four, five, six, seven or eight abreast seating to best suit their operational requirements.

Seating The extended-range airplanes typically have three-class seating of 181 to 245 passengers, using five-abreast, 747-sized first class seats; six-abreast business class and seven-abreast economy class.

CargoLower-deck volume available for baggage and cargo ranges from 2,875 cubic feet (81.4 cu m) for the 767-200 to 4,580 cubic feet (129.7 cu m) for the 767-400ER.

Takeoff WeightAll three passenger models are offered in a variety of takeoff weights, which allow operators to choose only the amount of design weight needed to satisfy their requirements. These offer corresponding design ranges from 5,625 nautical miles (10,415 km) to nearly 6,600 nautical miles (12,223 km).

This range versatility gives the 767 family the ability to efficiently serve routes as short as U.S. domestic and pan-European to long-range flights over the North Atlantic and North Pacific. The 767 crosses the Atlantic from the United States to Europe more often than any other jetliner.

Schedule reliability: An industry measure of departure from the gate within 15 minutes of scheduled time -- is over 98 percent for the 767. Fleet-wide, daily utilization -- the actual time the airplane spends in the air -- averages more than 9 hours.

Boeing has delivered 946 767s that are flown by approximately 125 operators around the world. The 767 family has accumulated more than 27 billion nautical miles on 7.7 million flights, and has carried two billion passengers. About 1.3 million of the 7.7 million flights were on extended operations (ETOPS) rules.

With its advanced-design wing and powerful engines, and at a maximum gross weight of 300,000 pounds (136,080 kg), the basic 767-200, can take off on only 5,700 feet (1,735 m) of runway. It can operate nonstop between New York and San Francisco with a two-class load of 224 passengers. Even the extended-range version of this airplane, the 767-200ER, with a maximum takeoff weight of 395,000 pounds (179,170 kg), can take off on about 8,100 feet (2,480 m) of runway. It can fly nearly 6,600 nautical miles (12,223 km), making possible such nonstop flights as New York to Delhi; London to Singapore; and Beijing to Sydney, Australia with 181 passengers in a three-class configuration.

Preferred By Passengers All passenger models of the 767 family offer a new, even more passenger-pleasing cabin interior. The Boeing Signature Interior, based on the award-winning design of the 777, uses state-of-the-art lighting and design concepts to amplify the feeling of spaciousness on an airplane already prized for long-range comfort.

For passengers, the new interior also includes new, deeper stowage bins, which means it is easier to find space in the compartments. For airlines, the new interior offers increased flexibility in positioning and maintaining lavatories. About 70 percent of the lavatory components are the same as those found on the 777, easing maintenance and reducing the number and type of spare parts in airlines inventories for operators of both models. The interior also features an improved in-flight entertainment interface.

The 767 has earned high passenger ratings in every class of service. In economy class seating, the 767 offers a seat-width that is only surpassed by the Boeing 777. Independent research has shown the seven-abreast seating concept in economy is popular because it places 87 percent of the seats next to a window or aisle. The 767 has the highest percentage of window seats and aisle seats of any jetliner.

1.2. History

Production Design Begins in 1981 with an Order from United AirlinesProduction design of the 767-200 began in 1978 when an order for 30 short-to-medium-range 767s was announced by United Airlines. The first 767 -- still owned by Boeing -- was completed and rolled out of the Boeing plant in Everett, Wash., Aug. 4, 1981. The airplane made its initial flight Sept. 26. 1981.

The 767-300 program got under way in September 1983. This model is longer than the 767-200 by 10 feet (3.1 m); has 20 percent more seating capacity (approximately 40 passengers) and 31 percent greater cargo volume. The first 767-300 was delivered to Japan Airlines in September 1986.

Each of these models was followed by an increased range (extended range or ER) version, which offers operators even more versatility. This increased range capability, and the 767s uniquely low operating costs are largely responsible for the fragmentation of the North Atlantic markets.

To take advantage of the airplanes increased ranges and long, over-water flights, new features were added: an advanced propulsion system and auxiliary power unit with high-altitude start capability, a fourth hydraulic-motor-driven generator, increased cargo compartment fire-suppression capability and cooling sensors for electronic flight instruments.

Continually Improved Features and Capabilities to Maintain Market LeadershipThe 767 wing is thicker, longer and less swept than the wings of earlier Boeing jetliners. This provides excellent takeoff performance and fuel economy. Each 767 is powered by two high-bypass-ratio turbofan engines, which are interchangeable with 747 engines with only minor modifications.

Type commonality with the 757 Freighter further reduces operating and training costs for carriers that choose to operate both models.

All the advancements in avionics, aerodynamics, materials and propulsion that were developed for the passenger version of the 767 are incorporated in the freighter.

The Boeing 767-400ER: A Versatile New Airplane For a Dynamic MarketThe newest member of the 767 family -- the 767-400ER -- was launched in April 1997 with an order from Delta Air Lines for 21 airplanes. This model features a fuselage that is 11 feet (3.4 m) longer than the 767-300ER model, and carries approximately 12 percent more passengers. The additional seats reduce seat-mile costs relative to the 767-300ER, which already offers airlines the lowest operating costs in its class.

This stretched version of the 767-300ER addresses the medium-size (240- to 300-seat) intercontinental market, accommodating growth on routes that dont require the capacity of a 777. The 767-400ER also replaces older airplanes serving transcontinental routes. The first 767-400ERs were delivered to Delta Air Lines and Continental Airlines in August 2000. The first 767-400ER went into service on Sept. 14, 2000.

Continually Improved Features and Capability To Maintain Market LeadershipThe 767 family has the lowest operating cost per trip of any widebody airplane. This low operating cost, combined with a choice of three sizes, variable range capability, almost universal airport compatibility and ETOPS capability, makes the 767 a versatile family of airplanes. This versatility is an extreme competitive advantage to an operator that needs to serve a variety of different missions and passenger demands. Extensive commonality with the Boeing 757, which includes a common pilot-type rating, offers even more operational versatility to 767 operators.

The Pioneer of Extended Operations (ETOPS)In May 1985, the U.S. Federal Aviation Administration (FAA) approved 767s for long-range flights of up to 120 minutes from an alternate airport. In March 1989, the FAA approved the 767 as the first jetliner for 180-minute extended operations (ETOPS). This allows more direct, time-saving trans-Pacific and trans-Atlantic flights from many U.S. gateways. After more than 15 years ETOPS has proven successful and is now part of airlines routine operations. 767s fly more ETOPS flights than any other airplane.

The 767-300 Freighter is the Preferred Solution for the Medium-Widebody Freighter MarketThe Boeing 767 Freighter was derived from the 767-300ER passenger airplane. It was launched in January 1993, and entered service in October 1995.

The main deck of the 767 Freighter can accommodate up to 24 pallets, each measuring 88 inches by 125 inches (233.5 cm by 317.5 cm) at the base. Total main deck container volume is 11,884 cu feet (336.6 cu m). The lower hold can accommodate seven pallets, two LD-2 containers, plus bulk. Total lower hold volume is 3,585 cubic feet (101.6 cu m).

These provide a combined maximum payload capability of 15,469 cu feet (438.2 cu m). When carrying the 59-tons(53.6 tonnes) maximum payload, the 767 Freighter has a range of 3,255 nautical miles (6,025 km).

The interior of the main-deck fuselage has a smooth, fiberglass lining. A fixed, rigid barrier installed in the front end of the main deck serves as a restraint wall between the cargo and the flight deck. A door in the barrier wall permits in-flight access from the flight deck to the cargo area.

The 767 Freighter keeps trip costs to a minimum with its two-person flight deck and twin high-bypass-ratio engines offering excellent fuel economy. This contrasts to older cargo-carrying airplanes, such as 707s and DC-8s, which have three-person flight crews and are powered by four engines.

It is designed to be the most efficient airplane in its size category, making it an ideal replacement for aging L-1011, DC-10-30 and A300 airplanes.

In growing markets, it can fly more passengers on routes served by existing 767s, A300-600s and A310s. Efficient design gives the higher-capacity 767-400ER excellent range capability (approximately 5,635 nautical miles or 10,415 km) to fly about 99 percent of the routes currently being served by airplanes in this size category.

The 767 has a long history of leading the way in technological innovation. Included in its list of firsts are:

First two-person flight deck on a widebody airplane First, and still the only, common pilot type rating, which is shared with

the Boeing 757 First vacuum toilet waste system First to use brakes made of carbon fiber First airplane to achieve both 120- and 180-minute ETOPS approval First widebody airplane to offer a choice of three passenger sizes -- the

767-200ER, 767-300ER and 767-400ER First large commercial airplane to use efficiency-enhancing raked

wingtips

Boeing has delivered more than 946 767s that are flown by 125 operators around the world. The 767 family has accumulated more than 27 billion nautical miles on 7.7 million flights, and has carried more than two billion passengers. About 1.3 million of the 7.7 million flights were on extended operations (ETOPS) rules.

The 767-400ER - brings significant improvements in operating economics over competing airplanes in the 240- to 300-seat market. The payload capability, intercontinental range, passenger comfort and commonality with other Boeing jetliners give this airplane strong market appeal.

Sized between the Boeing 767-300ER and the Boeing 777-200, the 767-400ER features a lengthened fuselage; aerodynamic improvements, including additional wing span; increased takeoff weight capability; and an all-new main landing gear.

The 767 Freighter is similar in external appearance to 767 passenger airplanes, except for the lack of passenger windows and doors. The interior of the main-deck fuselage has a smooth fiberglass lining. A fixed, rigid barrier installed in the front end of the main deck serves as a restraint wall between the cargo and the flight deck. A door in the barrier wall permits in-flight access from the flight deck to the cargo area.

Boeing has been the world leader in civilian air cargo since the 707 Freighter was introduced more than 30 years ago. As of March 2007, seven customers have ordered 83 767-300 Freighters.

767s produce less pollutant emissions per pound of fuel than any comparably sized jetliner, including the A330-200. When combined with the fact that the 767 also burns significantly less fuel, the 767 is truly the clear winner.

The 767 family is cleaner than industry standards for all categories of emissions -- nitrogen oxides, hydrocarbons, smoke and carbon monoxide.

The 767 family is cleaner than industry standards for all categories of emissions, nitrogen oxides, hydrocarbons, smoke and carbon monoxide.

In comparison with the Airbus A330-200, the 767-400ER offers superior economic performance -- with at least 5 percent lower operating costs. The 767-400ER weighs 40,000 pounds less than the A330-200.

The 767-400ER can fly all U.S. domestic routes as well as North Atlantic routes such as Los Angeles-London, Newark-Moscow or Chicago-Warsaw. Other potential routes include New York-Santiago, Chile; Seattle-Osaka and Atlanta-Honolulu.

The 767-400ER was launched April 28, 1997, when Atlanta-based Delta Air Lines announced its intent to order 21 airplanes.

Continental Airlines ordered 26 airplanes on Oct. 10, 1997. The first airplane rolled out of the Boeing factory Aug. 26, 1999 and

made its inaugural flight Oct. 9, 1999. The first 767-400ERs were delivered to Delta Air Lines and Continental

Airlines in August 2000. The first 767-400ER went into service on Sept. 14, 2000.

767 Fun Facts The 767 is the first widebody jetliner to be stretched twice. The 767-300ER

is 10 feet (3.1 m) longer than the 767-200ER; and the new 767-400ER is 11 feet (3.4 m) longer than the 767-300.

The first 767 entered service in Sept. 8, 1982, since then 767 have flown more than 7.7 million flights, and carried millions of passengers.

The air flowing through a 767-400ER engine at takeoff power could inflate the Goodyear Blimp in seven seconds.

It takes about 60 gallons (227 l) of fuel per passenger to get from New York to London on board a 767-400ER. The same volume of gasoline would propel an economy car about half of that distance.

The 767 is the favorite airplane on Atlantic routes; it flies across the Atlantic more frequently than any other airplane.

The 767-400ER flight deck instrument panel has 82 percent fewer parts than other 767s. By using cast parts, the part count was reduced to 53 from 296. Production hours plummeted to 20 hours from 180 hours.

If GE CF6-80C2B8F engines were attached to a typical automobile, at takeoff power the car would accelerate from zero to 60 mph (96.5 kph) in less than half a second.

There are 3.1 million parts in a 767 provided by more than 800 suppliers. The 767 is capable of cruising at altitudes up to 43,000 feet (13,106 m) The 767-300ER and 767-400ER hold 23,980 gallons (90,770 l) of fuel -

enough to fill 1,200 minivans. It takes only 28 minutes to fill the airplane. The noise level of a 767 taking off from a 1.5 mile (3,000 m) runway is

about the same as the average street corner traffic noise. There are 90 miles (145 km) of electrical wiring in a 767-200ER, 117 miles

(188 km) in a 767-300ER and 125 miles (201 km) in a 767-400ER.

767s burn less fuelThe 767 family of airplanes is the right size for the middle airplane market (200-250 seat airplanes). Lighter and more efficient than competing jetliners, the 767 family burns less fuel, for better environmental performance and improved operating economics.

Boeing wanted to give airlines a savings on weight and operating cost with the two-person flight deck. Because the 757 and 767 were developed at the same time, a basic design criteria was that the two airplanes be part of a family, having common pilot type rating and sharing many parts, systems, testing and manufacturing processes.

United Airlines was the first to order the 767 (July 14, 1978). After lengthy deliberation, the airline decided that a three-person crew would reduce the introductory risk associated with being the first to put the 767 into revenue service. Boeing continued to develop a second, two-crew version as an option for later customers. Contracts with major suppliers for the two-crew flight deck were being established as early as October 1978.

By the end of that year, three different flight-deck configurations were being planned. The hard-wired, or permanent, three-crew was to be introduced in August 1982 on the first 767 delivered to United. The 767 also would be available with a two-crew convertible option, meaning this design could be easily modified into a three-crew configuration. A third option, the three-crew convertible, was ready by February 1983. In this case, the design could be modified later to a two-crew configuration.

Boeing launched the 757 program in April 1979, and the first airplane was scheduled to roll out with the two-crew flight deck in January 1983. A three-crew convertible was to be ready for the 757 by April 1983.

The crew-size debate reached its peak in the spring of 1981, when a U.S. presidential task force was commissioned to determine the safety of two-crew operations for large widebody aircraft. After several months of hearings and extensive human-factors and safety data analyses, the task force concluded in July 1981 that two-crew operations could be conducted safely. This decision came less than a month before the first 767 was to roll out of the factory. Following the task force report, the United Airlines pilots union agreed to fly a two-crew 767. With similar agreements among other airlines and their pilots, the last major barrier to full acceptance of the two-pilot configuration was removed.

History of the 767 Two-Crew Flight DeckIn the post-deregulation period of the late 1970s, airlines were facing heavy price competition on routes that were now open to new rivals. At the same time, airplane system reliability, redundancy in the system design, and the exceptional record of the two-crew 737 led Boeing to examine the possibility of expanding the two-crew flight deck to the 757 and 767 design.

Airlines were interested in the two-crew aircraft for fleet expansion. Airbus was marketing its A310 and McDonnell Douglas its DC-9-80 -- both with two-pilot crews. Boeing believed that the long-term viability of the 757 and 767 would require the two-person flight deck, at least as an option.

FAA certification was awarded July 30, 1982, and United took first delivery August 19, 1982.

767-400ER FLIGHT DECKThe design is the latest advance toward a common look and feel in the flight decks of all Boeing airplanes. The instrument panel display layout and format shown here on a 767-400ER (extended range) airplane are also common with the Boeing 777, yet retains the cost-saving crew commonality with all current Boeing 767s and 757s. The flight deck also provides growth capacity for future system enhancements.

Eleven of the 12 airlines that had ordered the three-crew 767s changed their orders to the two-crew design. The timing of a change of this magnitude had enormous implications for 767 production and certification. Extensive planning and lead time were needed. The first structural parts went into production two years before the airplane was to roll out of the factory in August 1981. The first avionics system (an inertial navigation gyro) was delivered 20 months before rollout.

By September 1981, Boeing had developed the necessary plans to retrofit airplanes already produced with the three-crew flight deck and to incorporate the new design into the production line, beginning with the 31st airplane.

U.S. Federal Aviation Administration (FAA) certification proceeded on the first six airplanes produced. A seventh test airplane was added to the certification flight-test program after it had been retrofitted with the new digital flight deck. It took its first flight May 27, 1982 -- just three months after the 757 first flight. Boeing used the airplanes configured for three crew members to conduct certification tests that did not depend on the flight deck configuration. The crew size, workload and operational proof testing was conducted using the retrofitted two-crew test airplane.

To avoid slowing or interrupting the FAA certification process, Boeing chose to build the first 30 airplanes as fully functional (and certifiable) airplanes under the expected FAA certification for the three-crew model.

This decision was based on the companys ability to better control one of only two possible airplane configurations, rather than the many configurations that would have resulted if changes were incorporated on different airplanes at different stages of production.

Among the impacts of offering a two-crew flight deck were the cost of modifying 30 airplanes; the cost of the original design and installation of the three-person flight decks; and the delay of the delivery schedule (Boeing delivered 20 767s in 1982, eight fewer than planned).

To take advantage of the airplanes increased ranges and long, over-water flights, new features were added:

an advanced propulsion system and auxiliary power unit with high-altitude start capability,

a fourth hydraulic-motor-driven generator, increased cargo compartment fire-suppression capability and cooling sensors for electronic flight instruments.

Program Begins in 1981 with an Order from United AirlinesDesign of the 767-200 began in 1978 when an order for 30 767s was announced by United Airlines.

The first 767 -- still owned by Boeing -- was completed and rolled out of the Boeing plant in Everett, Wash., Aug. 4, 1981. First flight was Sept. 26, 1981.

The 767-300 program got under way in September 1983. The first 767-300 was delivered to Japan Airlines in September 1986.

Each of these models was followed by an increased range (extended range, or ER) version, which offers operators even more versatility. This increased range capability, and the 767s uniquely low operating costs are largely responsible for the fragmentation of the North Atlantic markets.

8.2. Electrostatic Discharge.

Electrostatic discharge can damage many electronic assemblies. Electrostatic discharge is the flow of electricity from a nonconductor. Rubbing or pulling apart two non-conductors generates static electricity. Most electronic assemblies are damaged by this electrostatic discharge, and therefore are called electrostatic discharge sensitive (ESDS).

The table shows typical electrostatic voltages generated from walking across a carpet and picking up a polyurethane bag from a bench, as examples. A person cannot feel less than 500 electrostatic volts. Damage to ESDS devices can occur with as little as 50 electrostatic volts. Improper handling of ESDS devices is almost certain to cause damage.

An electrostatic discharge failure can be soft or hard. Soft failures occur about 90% of the time and cause intermittent problems. Hard failures occur about 10% of the time and cause a failure of the component.

Handling Printed Circuit Cards.When replacing printed circuit cards, remove electrical power on the applicable system. Wear a wrist strap that is properly grounded. The wrist strap prevents a build-up of electrostatic charges. The wrist strap has a 1 meg ohm safety resistor to prevent electrical shock if you touch a high voltage source, such as 115 volts AC. Put the card into a printed circuit card carrier or a special conductive bag. Close the bag with an ESDS label.

Handling Computers.When replacing computers, remove electrical power on the applicable system. A wrist strap need not be worn. Remove the computer without touching the connectors on the back and install conductive caps. The conductive caps prevent an electrostatic discharge from reaching the pins in the back of the computer.

Both momentary and alternate action pushbutton switches are attached to a mounting sleeve by a detent and two spring loaded mounting lugs.

The mounting lugs are adjustable using mounting lug screws.

The cap assembly must be removed for access to the lamps. Make sure alternate action pushbutton switches are in the unlatched (out) position before the cap assembly is removed. This is accomplished by gently pulling on the cap assembly until the lock disengages from the cap assembly catch.

Bail wires hold the cap assembly to the master module assembly.

Lamp removal requires rotating the cap 90 degrees.

Changing the circuit module requires removing the master module assembly from the housing assembly. Remove cap assembly to gain access to mounting lug screws. The mounting lug screws should be turned counterclockwise with lugs stowed inside housing assembly. This allows the master module assembly to be pulled out from the housing assembly.

During reinstallation of the master module assembly check that wire follower is located in cam track with cam plate extended from master module assembly, and that bail wires are inside housing assembly.

Switch jamming will occur with wire follower out of track.

12. TOWING AND JACKING.

12.1. Towing.

Airplane towing is accomplished by tow tractor and towbar. Normal operation is accomplished by use of the nose gear forward tow fitting. Under body antennas and beacons have been located to enable towing from behind the nose gear with standard low profile tow tractors. Provisions have been made on the aft side of the nose gear to install an additional tow fitting. Each main landing gear has a towing eye at both ends. These points are used for abnormal situations such as airplane recovery.

The towing instructions are placarded below the towing lever. The towing lever is held in position with a lockpin. This locks out the nose gear hydraulic steering when towing even though hydraulic system is under pressure and permits turning up to 65. A red indicator strip painted on the nose gear doors indicates when a 65 nose gear turn is approaching.

If the nose gear angle may exceed 65 disconnect the torsion links prior to start the tow.

Manoeuvring the airplane on the ground is accomplished in a similar manner to other conventional geared airplanes. Nose wheel steering and engine thrust, as required, are used for taxiing. When taxiing the airplane the right hydraulic system provides normal pressure for the brake operation. The center hydraulic system provides alternate pressure for brake operation. If either hydraulic system fails, the brake accumulator holds a reserve of fluid under pressure for approximately six brake applications. The center hydraulic system provides hydraulic power for nose wheel steering.

General Operations.The specifications for jacking the 767 are given. The airplane may be raised in winds up to 30 knots if using jacks specifically designed for the airplane. If using jacks that meet the specifications but are not designed specifically for the 767, the maximum wind speed may have to be reduced and extreme caution should be exercised.

Flight mode is simulated when the airplane is jacked off the ground with electrical power applied. Deactivate the airplane systems which are adversely affected when air/ground relay system is in flight mode. See Maintenance Manual 07-11-01 for a list of the systems.

Make sure that the airplane gross weight and center of gravity (CG) are in the approved limits.

NOTE : The approved limits to lift the airplane on jacks are shown in the figure. The procedure to calculate the cross weight and the center of gravity is shown in the airplanes weight and balance manual.

CAUTION : DO NOT CHANGE THE CENTER OF GRAVITY WHEN THE AIRPLANE IS ON THE JACKS. DO NOT TRANSFER FUEL IN THE TANKS OR PERMIT THE MOVEMENT OF PERSONS AND EQUIPMENT IN OR NEAR THE AFT END OF THE FUSELAGE. ALL NECESSARY PRECAUTIONS MUST BE FOLLOWED OR DAMAGE TO THE AIRPLANE CAN OCCUR AIRPLANE JACKING WEIGHT AND CENTER OF GRAVITY LIMITS FOR JACKING AT PRIMARY JACK POINTS.

Jacking Airplane Nose.One jack point can be used to lift or lower the nose when the correct precautions are use. Also, the nose is lifted when the airplane is lifted fully, on jacks. A jack adapter must be installed at jack point D before the airplane is lifted.

CAUTION : MAKE SURE YOU EXTEND THE NOSE STRUT BEFORE THE AIRPLANE NOSE IS LIFTED AT JACK POINT D. WHEN THE NOSE IS LIFTED INDEPENDENTLY AND SUFFICIENTLY FOR TIRE CLEARANCE, UNUSUAL LOADS ARE CAUSED. JACK POINT D WILL MOVE IN AN ARC ABOUT 9CM (3 INCH) AFT AND CAUSE LOADS THAT ARE MORE THAN DESIGN LOAD LIMITS. THE BEND FORCE OF THE JACK RAM IS LESS THAN THE BREAKAWAY FORCE REQUIRED TO MOVE THE MAIN LANDING GEAR TIRES. DURING SOME CONDITIONS, JACK DAMAGE AND/OR DAMAGE TO THE AIRPLANE CAN OCCUR. THIS COULD MAKE THE RETRACTION OF THE JACK RAM NOT EASY OR NOT POSSIBLE.

Make sure that the landing gear downlocks are installed before lifting the nose.

Flight mode is simulated when the airplane nose is jacked off the ground with electrical power applied. Deactivate the airplane systems which are adversely affected when air/ground relay system is in flight mode.

See Maintenance Manual 07-11-01 for a list of the systems.

Make sure that the airplane gross weight and center of gravity (CG) are at approved limits.

Jacking Airplane Axles.The airplane has five (5) axle jack points. Two axle jack points are on each main landing gear. One axle jack point is on the nose landing gear.

The pads of the axle jack points are all part of the landing gear. The airplane can be lifted at the axle jack point at any airplane weight up to the maximum taxi weight.

The airplane may be lifted on one axle or on a combination of axles. If you use a jack on one axle, the airplane can be lifted in winds up to 35 knots. When two ore more axle jacks are used, the airplane can be lifted in winds up to only 25 knots.

Two flat tires on the same axle can prevent the use of standard axle jacks. If this occurs, you can use axle auxiliary jacking bars to lift the axle sufficiently to install the axle jack.

12.3. Leveling.

The airplane is supplied with one lateral and one longitudinal inclinometer, and a plumb bob leveling scale, as leveling indicators. The inclinometers and plumb bob leveling scale are on the keel beam near the front of the left main wheel well. For small adjustments to make the airplane level, the landing gear shock struts are inflated or deflated as necessary. For larger adjustments, the airplane must be lifted on jacks. Procedures to weight the airplane are included in the airplane Weight and Balance Manual.

WARNING : USE THE PROCEDURE IN 32-00-15 TO INSTALL THE DOOR LOCKS. THE DOORS OPEN AND CLOSE QUICKLY AND CAN CAUSE INJURY TO PERSONS OR DAMAGE TO EQUIPMENT.

13. FIM.

TYPES OF FAULTS EICAS Messages.There are different types of messages that show on the flight compartment displays to tell the flight crew of problems or other conditions of the airplane. These are the types (levels) of messages that can show on the display units :

- Warning (level A),- Caution (level B),- Advisory (level C),- Status (level S),- Maintenance (level M).

A warning message tells the flight crew of a condition that requires immediate crew action.

A caution message tells the flight crew of a condition that requires immediate crew awareness and possible crew action.

An advisory message tells the flight crew of a condition that requires crew awareness.

A status message gives information to the flight crew and maintenance crew about the dispatch status of the airplane. The maintenance crew can use the status messages together with the operators Minimum Equipment List (MEL).

A maintenance message is for the maintenance crew. It does not require flight crew attention. There wilt be a maintenance message for most of the conditions that make a status message show. The maintenance message can be the same as the status message. Typically, maintenance messages are inhibited in flight and wilt only show when the airplane is on the ground when the ECS/MSG page is selected.

General.This publication was prepared by Airplane Maintenance Data Engineering of the Boeing Commercial Airplane Group in accordance with Air Transport Association of America Specification No. 100, Specification for Manufacturers Technical Data. It contains information necessary to isolate and correct faults in systems and equipment installed in the 767 family of airplanes.

- The Fault Isolation Manual (FIM) and the Fault Reporting Manual (FRM) together provide a structured method for the airplane operator to report and correct faults in the airplane systems. (1) The FRM is primarily for the flight crews. It contains fault code diagrams to help the flight crew identify a unique 8-digit fault code and log book report for a fault.

- The FIM is primarily for the maintenance crews. It contains numerical indexes of alt the fault codes given in the FRM. The indexes wilt give the corrective action or a reference to a fault isolation procedure for each fault.

For general information about the manual numbering system, arrangement, and revision service refer to the introduction in the Airplane Maintenance Manual (AMM).

Observed Faults.Observed faults are problem symptoms sensed by the flight crew, maintenance crew, or cabin crew. These are the types of observed faults :

- Faults that are shown on the flight compartment panels and displays (other than EICAS messages) :

- Fault lights- Failure and alert flags- Other display messages- Indicated values and displays that are not normal.

- Flight crew observations in the flight compartment or during walk around.

- Servicing crew observations Ground maintenance crew observations- Problems with the systems and equipment in the passenger cabin

(cabin crew observations).

BITE Messages.Built-in test equipment (BITE) messages are the fault indications that you get from the BITE feature of the system or individual component. They help you find the cause of an EICAS message or observed fault. These are examples of typical types of BITE messages :

- A specific light or lights- An alphanumeric code- A group of English words or abbreviations, with or without an

associated numeric code.

You do most BITE tests at the front panel of components in the electronic equipment compartment or other equipment racks on the airplane. You do some BITE tests in the flight compartment.

EICAS MessagesMost chapters will have an EICAS Message table that shows all the EICAS messages for that chapter. The EICAS Message table gives the EICAS message, the level of the message, and the procedure to correct the fault.

The EICAS MESSAGE column shows the messages alphabetically. Messages that start with L (left), R (right), or C (center) are put together in this list starting with L.

Fault Code Diagrams.The Fault Code Diagrams give fault codes through problem analysis, for common faults that can occur on the airplane. Most of the diagrams are equivalent to the diagrams in the FRM. Other diagrams, shown by the word GROUND in the title, give the problem analysis and fault codes for ground crew operated systems.

The Fault Code Diagrams have five areas of data :

- The top area has the controls and the indicators applicable to each subject. These items are at the top of columns that extend into the analysis part of the diagram immediately below. You can also find questions in the top area.

- The middle area is an analysis that you can follow to find the applicable fault code. This area is intended to relate the specific system configuration to what has been observed. The analysis starts at an arrow on the left edge of the page and continues to the right and down. A diamond in a column shows where there are two or more answers to a question about the indicator or control. The diagram gives other possible indications or answers on lines that extend down and to the right of the diamond. The analysis continues until all faults that can occur for the diagram are included. Each fault has a line that extends into the Fault Code column at the right of the page.

- The column at the right of the page has the fault codes. Each fault has a fault code. This fault code is used to communicate a problem that was observed to the person who will do the troubleshooting. Fault codes that end with an X-alpha (XA, XB, etc.) are used for faults that cannot be identified in the FIM.

- The location part of the fault codes are specified in the top right corner of the page. These codes identify the specific part of the system or location where the fault occurred. Applicable circuit breakers for a system are at the bottom of the diagram.

Fault Code Index.The Fault Code Index is a numerical list of all fault codes for the chapter. For each fault code that is used, the index has these items :

- Item 1 is the problem report. This is a description of the fault. The problem report is equivalent to the logbook report entry in the FRM.

- Item 2 shows the steps to correct the fault. If a fault isolation procedure is necessary to correct the fault, then item 2 will refer to the applicable procedure.

BITE Index.The BITE Index is an alphabetical list of all the systems and components that have BITE procedures in the FIM. For each system or component, this list gives the chapter-section number where you can find the BITE procedure. Each BITE procedure will give the corrective action or a reference to a fault isolation procedure for each BITE message.

Component Location Data.Component location data is supplied for the major system components. The data is at the front of the applicable FIM chapter-section for the system or subsystem (subject). It is divided into two parts : The Component Index and the Component Location.

The Component Index is a table that list the components in a system or subsystem in alphabetical order. Components that are not assigned to the section or subject, but are operationally related, are also included with a reference to its own chapter-section. For each component, the Component Index table can have this data :

- A reference to the figure and sheet that shows the location of the component

- Quantity of each component- Access number of the door or panel that must be opened to get to the

component- Area, panel, or grid location (for circuit breakers) where the component

is located- A reference for the chapter-section-subject in the Airplane Maintenance

Manual (AMM) where the component is assigned.- Component Location figure shows the access and location of major

components in the Component Index. The components shown in relation to any structural or system features that near.

Fault Isolation Procedures.The Fault Isolation Procedures are used when one or more checks are necessary to find the cause of a fault. They are usually block flow diagrams that start with a description of a fault and end with the corrective action.

There are some Fault Isolation Procedures that are not block flow diagrams. These procedures can be in a tabular or text format.

Each Fault Isolation procedure has a PREREQUISITES box. The data in this box is used to make sure the systems that are necessary to do the fault isolation are in an operational condition.

For details on the structure and the content of the Fault Isolation Procedures, refer to the paragraph Fault Isolation Procedure Features that follows.

ARINC 429 Data Bus Charts.The data bus charts are supplied for many of the units that have an ARINC 429 data bus output transmitter (output port) that gives data to one or more other units with an ARINC 429 bus receiver (input port).

These charts show each transmitter data bus, each connector, the pins, the name of the bus, the word octal label, and the type of data. An ARINC 429 data bus transmitter and reader is necessary to monitor the buses for specific transmitted data.

Using The FIM to Isolate Faults.IF YOU HAVE A FAULT CODE for an observed fault (possibly reported by the flight crew), then use the Fault Code Index :

- Look at the first two digits of the fault code. This is the FIM ATA chapter number you need. Go to that chapter in the FIM and find the Fault Code Index near the front of the chapter.

- Find the fault code for the observed fault. The fault codes are shown in sequence by numbers with all the chapter X-alpha codes (XA, XB, etc.) shown first.

- To correct the fault, read the FAULT ISOLATION REFERENCE (item 2).

- If item 2 gives corrective action steps, then do the steps to repair the cause of the fault.

- If item 2 gives a figure and block reference, then go to the specified Fault Isolation Procedure in the FIM. Start at the referenced block and follow the procedure to isolate and repair the cause of the fault.

- If the fault code is an X-alpha fault code, then item 2 is usually a reference to the Wiring Diagram Manual (WDM) or System Schematics Manual (SSM). Use the flight crews description of the fault in the log book, and the referenced WDM or SSM diagram to isolate and correct the fault.

- If you corrected the fault, then return the airplane to service.

IF YOU HAVE NO FAULT CODE for an observed fault, then do these steps :

- EICAS MESSAGE. If the problem report has an EICAS message, then use the EICAS Messages list :

- If you know the chapter for the EICAS message, then do these steps :

- Go to the applicable chapter in the FIM and find the EICAS Messages list at the front of the chapter.

- Find the EICAS message in the list.- To correct the fault, read the PROCEDURE column for

the message.

- If the PROCEDURE column gives corrective action steps, then do the steps to repair the cause of the fault.

- If the PROCEDURE column gives a figure and block reference, then go to the specified Fault Isolation Procedure in the FIM. Start at the referenced block and follow the procedure to isolate and repair the cause of the fault.

- If you do not know the chapter for the EICAS message, then do these steps :

- Go to the EICAS MESSAGE LIST section in the FIM. This list is found after the INTRODUCTION to the FIM.

- Find the EICAS message in the table. The EICAS MESSAGE column shows the messages
