Resumo da Diretiva

PT-BRTradução automática

A FAA propõe adotar uma nova diretiva de aeronavegabilidade (DA) para certos aviões Airbus Canada Limited Partnership, modelos BD-500-1A10 e BD-500-1A11. Esta DA proposta foi motivada pela descoberta na linha de produção de que os chicotes do sistema elétrico no lavatório A apresentavam raios de curvatura reduzidos, não estavam adequadamente fixados e não atendiam aos requisitos de distanciamento de uma linha de abastecimento de oxigênio. Esta DA proposta exigiria uma inspeção da bainha e do chicote elétrico quanto a danos por abrasão e instalação incorreta, e ações conforme necessário aplicáveis. A FAA propõe esta DA para solucionar a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by the discovery on the production line that the electrical system harnesses in lavatory A had reduced bend radii, were not properly secured, and did not meet the requirement for clearance from an oxygen supply line. This proposed AD would require an inspection of the sleeve and electrical harness for chafing damage and incorrect installation, and applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.
