Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os helicópteros Airbus Helicopters Deutschland GmbH modelo MBB-BK 117 D-2 e MBB-BK 117 D-3. Esta DA foi motivada por relatos de erros de indicação de velocidade no ar e altitude. Esta DA requer a revisão do suplemento do manual de voo da aeronave giratória (SMVAG) existente para o helicóptero, a substituição das grades de saída do condensador do sistema de ar condicionado (SAC) por tampas de saída do condensador do SAC, e proíbe a instalação de grades de saída do condensador do SAC. A FAA está emitindo esta DA para corrigir a condição insegura nesses produtos.
