Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para certos helicópteros Airbus Helicopters modelos AS 332L2 e EC 225LP. Esta DA foi motivada por relatos de parafusos de fixação sobreelongados e deformados instalados na ligação do suporte de fixação da barra de suspensão da caixa de engrenagens principal (CEP). Esta DA exige a substituição de certos parafusos de fixação nos encaixes da barra de suspensão da CEP, inspeção dos parafusos removidos e comunicação dos resultados desta inspeção à Airbus Helicopters. A FAA está emitindo esta DA para resolver a condição insegura nestes produtos.
