Airworthiness Directive 2016-07843
one-timeAirworthiness Directives; GE Aviation Czech s.r.o. Turboprop Engines
What this AD requires
We are adopting a new airworthiness directive (AD) for certain GE Aviation Czech s.r.o. M601E-11 turboprop engines. This AD requires inspection of the engine power turbine (PT) disk and, if found damaged, its replacement with a part eligible for installation. This AD was prompted by discovery of damage to certain engine PT disks during engine shop visits. We are issuing this AD to prevent failure of the engine PT disk, which could result in release of high-energy debris, damage to the engine, and reduced control of the airplane.
Which aircraft AD 2016-07843 applies to
Applies only to engines with power turbine (PT) disk P/N 3220.6 bearing S/N EE8, EF8, or KR5 installed.
Whether AD 2016-07843 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
