Airworthiness Directives; Honeywell International Inc. ATF3-6 and ATF3-6A Series Turbofan Engines
Локальный автоматический перевод · Язык оригинального источника
Краткое содержание
The FAA proposes to adopt a new airworthiness directive (AD) for Honeywell International Inc. ATF3-6 and ATF3-6A series turbofan engines equipped with a certain part number (P/N) low pressure compressor (LPC) aft shaft. This proposed AD would require removing from service those LPC aft shafts and installing a serviceable LPC aft shaft. This proposed AD results from reports of eight LPC aft shafts found cracked during fluorescent penetrant inspection (FPI). We are proposing this AD to prevent uncoupling and overspeed of the low pressure turbine, which could result in uncontained engine failure and damage to the airplane.
