Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os aviões Falcon 7X da Dassault Aviation. Esta DA foi motivada por vazamento hidráulico da unidade de controle de potência do spoiler (SPPCU) em operação. As investigações relevantes determinaram que, após certas falhas, a unidade de controle elétrico do spoiler (SPECU) pode entregar um comando de ativação intempestivo e permanente à bomba elétrica de espera da SPPCU, o que pode resultar em superaquecimento e vazamento hidráulico significativo da unidade. Esta DA exige a substituição das SPECUs afetadas e proíbe a instalação de peças afetadas. A FAA está emitindo esta DA para abordar a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA is adopting a new airworthiness directive (AD) for all Dassault Aviation Model Falcon 7X airplanes. This AD was prompted by hydraulic leakage from the spoiler power control unit (SPPCU) in service. Relevant investigations determined that, following certain failures, the spoiler electrical control unit (SPECU) can deliver an untimely and permanent activation command to the SPPCU standby electrical pump, which can possibly result in overheating and significant hydraulic leakage of the unit. This AD requires replacing the affected SPECUs and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
