Airworthiness Directives; GE Aviation Czech s.r.o. Turboprop Engines

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.
