Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para determinados aviões Airbus Canada Limited Partnership Modelo BD-500-1A10 e BD-500-1A11. Esta DA foi motivada por eventos relatados de travamentos do atuador de compensação de estabilizador horizontal (ACEH) ocorrendo ao final da fase de cruzeiro do voo. Esta DA exige lubrificação do ACEH utilizando um método aprimorado, em intervalo reduzido, conforme especificado em uma DA da Transport Canada, a qual é incorporada por referência. A FAA está emitindo esta DA para abordar a condição de segurança inadequada nestes produtos.

This AD requires lubricating the HSTA using an improved method, at a reduced interval, as specified in a Transport Canada AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
