A FAA propõe adotar uma nova diretiva de aeronavegabilidade (AD) para certos helicópteros Airbus Helicopters Deutschland GmbH (AHD) Modelo MBB-BK 117 D-3. Esta AD proposta foi motivada por relatos de interrupção momentânea de energia em corrente contínua (CC) em voo em ambos os barramentos essenciais. Esta AD proposta exigiria a revisão do manual de voo de helicóptero (RFM) existente para seu helicóptero, conforme especificado em uma AD da Agência Europeia de Segurança da Aviação (EASA), que é proposta para incorporação por referência. A FAA está propondo esta AD para abordar a condição insegura nesses produtos.

This proposed AD would require revising the existing rotorcraft flight manual (RFM) for your helicopter, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is proposing this AD to address the unsafe condition on these products.
