Resumo da Diretiva
A FAA está adotando uma nova Diretriz de Aeronavegabilidade (AD) para todos os helicópteros Airbus Helicopters modelo AS350B2, AS350B3, EC120B e EC130B4. Esta AD foi motivada por um curto-circuito causado por corpos estranhos (FOD) ou poeira dentro da unidade de controle de iluminação e auxiliares (LACU). Esta AD exige limpeza e inspeção repetitivas da LACU afetada para detecção de FOD. Dependendo da configuração do helicóptero, esta AD também exige modificação dos interruptores de ativação do sistema de flutuação de emergência (EFS) e revisão do Manual de Voo da Aeronave (RFM) existente para o helicóptero, o que constituiria uma ação de encerramento dos requisitos de limpeza e inspeção repetitivas. Além disso, esta AD proíbe a instalação de uma LACU afetada em qualquer helicóptero, a menos que certos requisitos sejam atendidos. A FAA está emitindo esta AD para abordar a condição insegura nestes produtos.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model AS350B2, AS350B3, EC120B, and EC130B4 helicopters. This AD was prompted by a short-circuit due to foreign object debris (FOD) or dust inside the lighting and ancillaries control unit (LACU). This AD requires repetitively cleaning and inspecting the affected LACU for FOD. Depending on the configuration of the helicopter, this AD also requires modifying the emergency floatation system (EFS) activation switches and revising the existing rotorcraft flight manual (RFM) for the helicopter, which would constitute a terminating action for the repetitive cleaning and inspection requirements. Additionally, this AD prohibits installing an affected LACU on any helicopter unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
