Resumo da Diretiva

PT-BRTradução automática

A FAA propõe adotar uma nova diretiva de aeronavegabilidade (DA) para certos motores Modelo CF6-80E1A2, CF6-80E1A3, CF6-80E1A4 e CF6-80E1A4/B da General Electric Company (GE). Esta DA proposta foi motivada por investigação do fabricante que revelou que certos discos de turbina de alta pressão (TAP) estágio 1 e TAP estágio 2 foram fabricados a partir de material de metal em pó suspeito de conter inclusão de ferro. Esta DA proposta exigiria a substituição dos discos de TAP estágio 1 e TAP estágio 2 afetados por peças elegíveis para instalação. A FAA está propondo esta DA para abordar 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 CF6-80E1A2, CF6-80E1A3, CF6-80E1A4, and CF6-80E1A4/B engines. This proposed AD was prompted by a manufacturer investigation that revealed certain high-pressure turbine (HPT) stage 1 and HPT stage 2 disks were manufactured from powder metal material suspected to contain iron inclusion. This proposed AD would require replacement of affected HPT stage 1 and HPT stage 2 disks with parts eligible for installation. The FAA is proposing this AD to address the unsafe condition on these products.
