TH-67 OPERATOR’S SUPPLEMENT TH-67 OPERATOR’S SUPPLEMENT

SYMBOLS DEFINITION * ─ Indicates performance of steps is mandatory for all

thru-flights. (I) ─ Indicates peculiarity for IFR configured helicopter.

─ Indicates that expanded procedures are contained in the Performance "P" Section of the checklist.

─ Indicates items also covered for passenger briefing.

A+ ─ Indicates peculiarity for A+ configured helicopter.

NOTE This checklist is intended to serve as a convenient

reference to the detailed procedures presented in the TH-67 Operator's Supplement and the FAA approved Flight Manual. The preflight check is not intended to be a detailed mechanical inspection, but a guide to help the pilot check the condition of the helicopter. It may be made as comprehensive as conditions warrant at the discretion of the pilot. All areas checked shall include a visual check for evidence of corrosion, particularly when the helicopter is flown near or over salt water or in areas of high industrial emissions.

PREFLIGHT CHECK
