Resumo da Diretiva
A FAA está revogando a Diretriz de Aeronavegabilidade (DA) 2021-08-02 para todos os Motores de Helicóptero Safran, S.A. (Safran) (certificado de tipo anteriormente mantido pela Turbomeca, S.A.) modelos Arriel 2D e Arriel 2E. A DA 2021-08-02 exigia a substituição de determinadas peças críticas antes de atingir seus limites de vida útil em serviço publicados, a execução de tarefas de manutenção programada antes de atingir suas periodicidades publicadas e a execução de tarefas de manutenção não programada quando o motor atendesse a certas condições. Desde que a FAA emitiu a DA 2021-08-02, a Safran revisou a seção de limitações de aeronavegabilidade (ALS) dos manuais existentes de manutenção e revisão geral, introduzindo instruções e tarefas de manutenção novas e mais restritivas, o que motivou esta ação de DA. Esta DA exige a atualização da ALS do manual de manutenção do motor (EMM) ou instruções para aeronavegabilidade continuada (ICA) existente e do programa existente de manutenção ou inspeção aprovado, conforme aplicável, incorporando as ações e seus limites e intervalos associados, incluindo limites de vida útil, conforme especificado em uma DA da Agência da União Europeia para a Segurança da Aviação (EASA), que é incorporada por referência. A FAA está propondo esta DA para abordar a condição insegura nestes produtos.
The FAA is superseding Airworthiness Directive (AD) 2021-08-02 for all Safran Helicopter Engines, S.A. (Safran) (type certificate previously held by Turbomeca, S.A.) Model Arriel 2D and Arriel 2E engines. AD 2021-08-02 required replacing certain critical parts before reaching their published in-service life limits, performing scheduled maintenance tasks before reaching their published periodicity, and performing unscheduled maintenance tasks when the engine meets certain conditions. Since the FAA issued AD 2021-08-02, Safran has revised the airworthiness limitation section (ALS) of the existing maintenance and overhaul manuals, introducing new and more restrictive instructions and maintenance tasks, which prompted this AD action. This AD requires updating the ALS of the existing engine maintenance manual (EMM) or instructions for continued airworthiness (ICA) and the existing approved maintenance or inspection program, as applicable, by incorporating the actions and associated thresholds and intervals, including life limits, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
