Airworthiness Directives; GE Aviation Czech s.r.o. Turboprop Engines (Type Certificate Previously Held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.)

FAA / Federal Register · 2020-16122

The FAA is adopting a new airworthiness directive (AD) for all GE Aviation Czech s.r.o. M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, M601F, H80, H80-100, H80-200, H75-100, H75-200, H85-100, and H85-200 model turboprop engines. This AD was prompted by a review by the manufacturer that identified the possibility of a power turbine (PT) rotor overspeed and the uncontained release of PT blades. This AD requires installing a modified engine outlet system. The FAA is issuing this AD to address the unsafe condition on these products.
