Resumo da Diretiva

PT-BRTradução automática

A FAA propõe a adoção de uma nova diretiva de aeronavegabilidade (DA) para todas as aeronaves da série Model 737-600, -700, -700C, -800, -900 e -900ER, fabricadas pela The Boeing Company. Esta DA proposta foi motivada por um relatório de porcas não apertadas adequadamente e ausentes no conjunto de cardan inferior do atuador de compensação do estabilizador horizontal (HSTA). Esta DA proposta exigiria uma revisão dos registros de manutenção para determinar se um HSTA revisado foi inspecionado e se as ações corretivas foram executadas de acordo com certas informações de serviço e as ações aplicáveis conforme a condição. A FAA está propondo esta DA para tratar a condição de insegurança nestes produtos.

ENOriginal (Federal Register)

The FAA proposes to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a report of under-torqued and missing nuts on the horizontal stabilizer trim actuator (HSTA) lower gimbal assembly. This proposed AD would require a review of maintenance records to determine if an overhauled HSTA was inspected and corrective actions were accomplished using certain service information, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
