✈️Proposed Airworthiness Directive for GE Aviation Engine Compliance
The FAA proposes to supersede Airworthiness Directive (AD) 2024-06-02, which applies to all GE Aviation Czech s.r.o. (GEAC) Model M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S, and M601F engines. AD 2024-06-02 was prompted by a report of a crack on the centrifugal compressor case mount pad weld area caused by a non- conforming weld (lack of welding penetration). AD 2024-06-02 requires a one-time detailed visual inspection (DVI) of the compressor case pad welds for any crack, and replacement of the compressor case if necessary. Since the FAA issued AD 2024-06-02, the manufacturer determined that the compliance time for the DVI can be extended, and repetitive inspections of the centrifugal compressor case must be accomplished. This proposed AD would require performing repetitive DVIs of the compressor case pad welds for any crack, replacing the compressor case if necessary, and sending certain inspection results to the manufacturer, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.

This action withdraws the NPRM published in the Federal Register on March 20, 2025, proposing to establish Class E airspace at Wickenburg, AZ. The FAA has determined that withdrawal of that NPRM is warranted as new airspace data has been received which significantly changes the proposed airspace.

The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus SAS Model A318, A319, A320, and A321 series airplanes. This proposed AD was prompted by a heavy maintenance check that found elongation on the upper section of the vertical member's assembly at the frame (FR) 24A cargo panel sub-structure. This proposed AD would require a check for certain repairs, and as applicable, repetitive detailed visual inspections of the vertical member's upper part and the upper fittings at FR 24A in the forward cargo compartment and corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.
