Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (AD) para todos os aviões Bombardier, Inc., Modelo CL-600-2B16 (Variante 604). Esta AD foi motivada por relatórios indicando que o gravador a bordo do sistema de abas (FSOBR) interage com os sinais da unidade de controle de abas e pode resultar no acionamento dos monitores da unidade de controle de abas, causando mensagens de Falha de Abas e possivelmente movimento não comandado das abas. Esta AD exige a desconexão do FSOBR e proíbe a instalação futura deste sistema. A FAA está emitindo esta AD para resolver a condição insegura nestes produtos.

The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model CL-600-2B16 (604 Variant) airplanes. This AD was prompted by reports that the flap system on-board recorder (FSOBR) interfaces with the flap control unit signals and may result in the flap control unit monitors tripping, causing Flap Fail messages and possibly an uncommanded flap movement. This AD requires the disconnection of the FSOBR and prohibits future installation of this system. The FAA is issuing this AD to address the unsafe condition on these products.
