Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os helicópteros Airbus Helicopters modelo EC 155B, EC155B1, SA-365N, SA-365N1, AS-365N2 e AS 365 N3. Esta DA foi motivada por um incêndio no compartimento do motor, no qual o reforçador superior da parede corta-fogo central no compartimento do motor foi encontrado danificado. Esta DA requer a substituição do reforçador de parede corta-fogo central de alumínio por um reforçador de parede corta-fogo central de titânio e proíbe a instalação de um reforçador de parede corta-fogo central de alumínio. Essas ações estão especificadas em uma DA da Agência de Segurança Aeronáutica da União Europeia (EASA), que é incorporada por referência. A FAA está emitindo esta DA para abordar a condição insegura nesses produtos.
