Resumo da Diretiva
A FAA propõe substituir a Diretiva de Aeronavegabilidade (DA) 2021-20-16, que se aplica a todos os helicópteros Airbus Helicopters Modelo AS355E, AS 355-F, AS 355-F1, AS355F2, AS355N e AS355NP e determinados helicópteros Modelo AS 350B3. A DA 2021-20-16 exige limpeza repetitiva e inspeções visuais e detalhadas do lado direito da asa vertical do estabilizador e dos suportes superiores da asa vertical quanto a discrepâncias (trincas) com ação corretiva, se necessário. Desde que a FAA emitiu a DA 2021-20-16, a Airbus Helicopters desenvolveu uma modificação do conjunto da asa superior. Esta DA proposta exigiria as mesmas ações da DA 2021-20-16 e também exigiria a substituição do conjunto da asa superior por um conjunto de asa superior modificado, o que constituiria uma ação de término para as inspeções repetitivas. A FAA está propondo esta DA para abordar a condição de segurança inadequada nesses produtos.
The FAA proposes to supersede Airworthiness Directive (AD) 2021-20-16, which applies to all Airbus Helicopters Model AS355E, AS 355-F, AS 355-F1, AS355F2, AS355N, and AS355NP helicopters and certain Model AS 350B3 helicopters. AD 2021-20-16 requires repetitive cleaning and visual and detailed inspections of the right-hand side of the vertical fin spar and vertical fin upper attachments for discrepancies (cracking) with corrective action, if necessary. Since the FAA issued AD 2021-20-16, Airbus Helicopters developed a modification of the upper fin assembly. This proposed AD would require the same actions as AD 2021-20-16 and would also require replacement of the upper fin assembly with a modified upper fin assembly, which would constitute terminating action for the repetitive inspections. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
