Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os helicópteros Airbus Helicopters modelo SA341G e SA342J. Esta DA foi motivada por relatos de corrosão nas superfícies de contato dos flanges do eixo comando inclinado e horizontal do rotor de cauda. Esta DA exige inspeção repetitiva dos flanges do eixo comando inclinado e horizontal e, dependendo dos resultados, substituição do eixo comando inclinado ou horizontal. Esta DA também proíbe a instalação de certos eixos comando inclinado e horizontal, a menos que certos requisitos sejam atendidos. Essas ações são especificadas em uma DA da Agência Europeia para a Segurança da Aviação (EASA), que é proposta para incorporação por referência. A FAA está emitindo esta DA para resolver a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA is adopting a new airworthiness directive (AD) for all Airbus Helicopters Model SA341G and SA342J helicopters. This AD was prompted by reports of corrosion on the contact surfaces of the tail rotor inclined and horizontal drive shaft flanges. This AD requires repetitively inspecting the inclined and horizontal drive shaft flanges and, depending on the results, replacing the inclined or horizontal drive shaft. This AD also prohibits installing certain inclined and horizontal drive shafts unless certain requirements are met. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference. The FAA is issuing this AD to address the unsafe condition on these products.
