Resumo da Diretiva

PT-BRTradução automática

A FAA propõe adotar uma nova diretiva de aeronavegabilidade (DA) para certos helicópteros modelo 407 da Bell Textron Canada Limited (Bell). Esta DA proposta foi motivada por um relatório de um tubo de comando cíclico do piloto fraturado e descobertas subsequentes de outros tubos de comando cíclico do piloto com trincas por fadiga. Esta DA proposta exigiria inspeções repetitivas do conjunto do tubo de comando cíclico do piloto quanto a trincas e, dependendo dos resultados, reparo ou substituição do conjunto do tubo de comando cíclico do piloto. A FAA está propondo esta DA para remediar a condição insegura nestes produtos.

ENOriginal (Federal Register)

The FAA proposes to adopt a new airworthiness directive (AD) for certain Bell Textron Canada Limited (Bell) Model 407 helicopters. This proposed AD was prompted by a report of a fractured pilot cyclic stick tube and subsequent findings of other pilot cyclic stick tubes with fatigue cracking. This proposed AD would require repetitively inspecting the pilot cyclic stick tube assembly for a crack and, depending on the results, repairing or replacing the pilot cyclic stick tube assembly. The FAA is proposing this AD to address the unsafe condition on these products.
