Resumo da Diretiva
A FAA propõe revogar a Diretiva de Aeronavegabilidade (DA) 2024-06-02, que se aplica a todos os motores GE Aviation Czech s.r.o. (GEAC) Modelos M601D-11, M601E-11, M601E-11A, M601E-11AS, M601E-11S e M601F. A DA 2024-06-02 foi motivada por um relato de trinca na área de solda do coxim de montagem do compressor centrífugo causada por uma solda não conforme (falta de penetração de soldagem). A DA 2024-06-02 exige uma inspeção visual detalhada (IVD) única das soldas do coxim do compressor quanto a qualquer trinca e substituição do compressor se necessário. Desde que a FAA emitiu a DA 2024-06-02, o fabricante determinou que o prazo de conformidade para a IVD pode ser estendido e inspeções repetitivas do compressor centrífugo devem ser realizadas. Esta DA proposta exigiria realizar inspeções visuais detalhadas repetitivas das soldas do coxim do compressor quanto a qualquer trinca, substituir o compressor se necessário e enviar certos resultados de inspeção ao fabricante, conforme especificado em uma DA da Agência Europeia de Segurança da Aviação (EASA), que é proposta para incorporação por referência. A FAA propõe esta DA para abordar a condição insegura nesses produtos.
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.Texto Completo da Diretiva

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: 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. DATES: The FAA must receive comments on this NPRM by June 9, 2025.
