Resumo da Diretiva

PT-BRTradução automática

A FAA propõe adotar uma nova diretiva de aeronavegabilidade (AD) para certos motores General Electric Company (GE) Modelos CF34-8C1, CF34-8C5, CF34-8C5A1, CF34-8C5A2, CF34-8C5A3, CF34-8C5B1, CF34-8E2, CF34-8E2A1, CF34-8E5, CF34-8E5A1, CF34-8E5A2, CF34-8E6 e CF34-8E6A1. Esta AD proposta foi motivada por uma redução prevista na vida cíclica do flange dianteiro do conjunto da câmara de combustão (CCA). Esta AD proposta exigiria inspeções por líquido penetrante fluorescente (FPI) do CCA para detectar qualquer indicação e substituição, se necessário. A FAA está propondo esta AD para resolver a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA proposes to adopt a new airworthiness directive (AD) for certain General Electric Company (GE) Model CF34-8C1, CF34-8C5, CF34-8C5A1, CF34-8C5A2, CF34-8C5A3, CF34-8C5B1, CF34-8E2, CF34-8E2A1, CF34-8E5, CF34-8E5A1, CF34-8E5A2, CF34-8E6, and CF34-8E6A1 engines. This proposed AD was prompted by a predicted reduction in the cyclic life of the combustion chamber assembly (CCA) forward flange. This proposed AD would require fluorescent penetrant inspections (FPIs) of the CCA for any indications and replacement if necessary. The FAA is proposing this AD to address the unsafe condition on these products.
