Resumo da Diretiva

PT-BRTradução automática

A FAA propõe adotar uma nova Diretiva de Aeronavegabilidade (DA) para todos os aviões das séries Boeing 777-200, -200LR, -300, -300ER e 777F. Esta DA proposta foi motivada por um relato de bombas de motor de corrente alternada (ACMP) superaquecidas que causaram incêndio no poço da roda do trem de pouso principal (MLG). Esta DA proposta exigiria uma verificação de registros ou inspeção para qualquer ACMP instalada com determinado número de peça e ações condicionais aplicáveis. Esta DA proposta também proibiria a instalação de peças afetadas. A FAA está propondo esta DA para resolver a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 777-200, -200LR, -300, -300ER, and 777F series airplanes. This proposed AD was prompted by a report of overheated alternating current motor pumps (ACMP) that caused a fire in the main landing gear (MLG) wheel well. This proposed AD would require a records check or inspection for any installed ACMP with a certain part number and applicable on-condition actions. This proposed AD would also prohibit the installation of affected parts. The FAA is proposing this AD to address the unsafe condition on these products.
