Résumé
The FAA proposes to supersede Airworthiness Directive (AD) 2022-13-16, which applies to all GE Aviation Czech s.r.o. (GEAC) (type certificate previously held by WALTER Engines a.s., Walter a.s., and MOTORLET a.s.) Model M601D-11 engines; and AD 2022-14-12, which applies to certain GEAC Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E- 11S, and M601F engines. AD 2022-13-16 requires revising the airworthiness limitations section (ALS) of the existing engine maintenance manual (EMM) to incorporate a visual inspection of the centrifugal compressor case for cracks. AD 2022-14-12 requires replacing the propeller shaft for Model M601F engines. AD 2022-14-12 also requires calculating the accumulated life of the propeller shaft and replacing the propeller shaft, if necessary, for model M601D-11, M601E-11, M601E-11A, M601E-11AS, and M601E-11S engines. Since the FAA issued AD 2022-13-16 and AD 2022-14-12, the manufacturer revised the ALS of the existing EMM to introduce new and more restrictive tasks and limitations, expand the applicability to all Model M601 engines, and incorporate certain requirements addressed by AD 2021-13-07 and AD 2023-01-10, which prompted this proposed AD.
