The FAA proposes to adopt a new airworthiness directive (AD) for certain GE Aviation Czech s.r.o. M601E-11, M601E-11A, M601E-11AS, M601E-11S and M601F model turboprop engines. This proposed AD was prompted by the exclusion of life limits for certain compressor cases and compressor drums from the airworthiness limitations section of the engine maintenance manual.
This proposed AD would require recalculation of the consumed life for the affected compressor cases and compressor drums and, depending on the results of the recalculation, removal and replacement of the affected compressor case or compressor drum with a part eligible for installation.
The proposed AD may be viewed here. If adopted, the AD would require action within 90 days after the effective date of the AD.
