Description

1 GeneralThis publication gives you all the data necessary for the maintenance planning of theAgustaWestland AW139 helicopter.

The maintenance planning information includes the chapters that follow applicable to thehelicopter maintenance information:

– Chapter 04 - Airworthiness limitations.– Chapter 05 - Schedules/unscheduled maintenance requirements.

The publications that follow give more data about the maintenance of the helicopter:

– Maintenance Publication (39-A-AMP-00-P).– Fault Isolation Publication (39-A-AFIP-00-P).– Wiring Data Publication (39-A-AWDP-00-P).

The data necessary for the repair and overhaul of the components removed from the helicopterare given in the Component Repair and Overhaul publication (39-A-CR&OP-00-P).

The data necessary for the repair of the helicopter structure are given in the Structural Repairpublication (39-A-ASRP-00-P).

All the maintenance data are included in data modules. A code identifies each data module. Referto Para 2 for the structure of the Data Module Code (DMC).

2 Data Module Code (DMC)The DMC structure is shown in Table 2.

Table 2 DMC structure

2.1 Model identification codeThe model identification code for the AW139 is 39.

2.2 System difference codeThe system difference code is a letter (letters I and O are not used).

This letter identifies two or more sub-systems that can be installed as alternative items becausethey do the same function (eg: VHF systems by different suppliers).

2.3 Standard Numbering System (SNS) codeThe SNS code includes three pairs of digits which show:

– The system (eg: 29, hydraulic power).– The sub-system and sub-subsystem (eg: 11, Number 1 main-hydraulic system).

Note When the sub-subsystem code is zero, the two digits show all of the sub-system.

– The component (eg: 01, Number 1 power-control module).

Refer to Para 3 for the list of the system numbers.

2.4 Disassembly code and disassembly code variant

2.4.1 Disassembly codeThe disassembly code is a two-digit code.

The disassembly code shows the breakdown of a component, as follows:

– 00 - Data module for all of the helicopter, system, sub-system or component.– 01 - Data module for the first assembly that you remove from the component.– 02 - Data module for the second assembly that you remove from the component.

Code 03 and the subsequent codes refer to the third, fourth, etc assembly that you remove fromthe component.

The disassembly code also identifies the data modules in sequence.

2.4.2 Disassembly code variantThe disassembly code variant is a letter (letter I and O are not used) which identifies alternativeitems.

These items are different, but the difference is too small to cause a change in the systemdifference code.

2.5 Information code and information code variant

2.5.1 Information codeThe information code is a three-digit code.

The information code identifies the types of information you can find in the data module.

000 is used for the systems, for which the SNS identifies the type of information in the data module(eg: 05-10 is “time limits”, you must write 000).

The primary codes used in the publication set for the helicopter are written in Table 3.

39-A-AMPI-00-P

Table 3 Primary information codes

2.5.2 Information code variantThe information code variant is a letter (letters I and O are not used).

The information code variant is used for different data modules that are applicable to the samecomponent and type of operation.

2.6 Item location codeThe item location code is a letter which shows where you must do the maintenance task.

In this publication, you can find these item location codes:

– A on the helicopter.– B on the removed assembly/component.– C on the removed assembly/component at repair/overhaul level.– D applicable to all the locations.

The letter K is used as the item location code for the identification of the data modulesapplicable to:

– Optional installations.
