Resumo da Diretiva
A FAA está revogando a Diretriz de Aeronavegabilidade (DA) 2023-01-04 para todos os helicópteros Airbus Helicopters modelos AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N e AS355NP. A DA 2023-01-04 exigia, para helicópteros com unidades de mudança de passo tipo spider da cabeça do rotor de cauda com números de peça específicos instaladas, inspeção da porca spider de mudança de passo (porca) quanto à instalação correta; marcação de um índice de tinta preta com largura de 2 a 5 mm e inspeção repetitiva do alinhamento da marcação; e execução de inspeções adicionais e ações corretivas se necessário. Desde que a FAA emitiu a DA 2023-01-04, novas ou mais restritivas limitações de aeronavegabilidade foram emitidas, o que eliminou a exigência das inspeções repetitivas da marcação de índice de tinta preta. Esta DA exige as mesmas ações da DA 2023-01-04, com exceção das inspeções repetitivas da marcação de índice de tinta preta, e proíbe a instalação de certas peças a menos que certos requisitos sejam atendidos. A FAA está emitindo esta DA para solucionar a condição insegura destes produtos.
The FAA is superseding Airworthiness Directive (AD) 2023-01-04 for all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350D, AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters. AD 2023-01-04 required, for helicopters with certain part- numbered tail rotor head (TRH) spider pitch change units installed, inspecting the pitch change spider nut (nut) for correct installation; marking a 2 to 5 mm wide black paint index mark and repetitively inspecting the alignment of the marking; and performing additional inspections and corrective actions if necessary. Since the FAA issued AD 2023-01-04, new or more restrictive airworthiness limitations were issued, which terminated the requirement for the repetitive inspections of the black paint index marking. This AD requires the same actions as AD 2023-01-04, except for the repetitive black paint index marking inspections and prohibits installing certain parts unless certain requirements are met. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
