Resumo da Diretiva
A FAA propõe substituir a Diretriz de Aeronavegabilidade (DA) 2022-15-01, que se aplica a certos aviões Boeing Modelo 787-8, 787-9 e 787-10. A DA 2022-15-01 exige inspeção de certos furos de parafuso de tensão da deriva vertical; revisão do procedimento de instalação da aplicação de selante dos parafusos no programa de manutenção ou inspeção existente, conforme aplicável; verificação dos registros de manutenção para determinar o status de substituição dos parafusos de tensão da deriva vertical; e execução das ações condicionais aplicáveis. Desde que a FAA emitiu a DA 2022-15-01, a FAA determinou que os tipos de selante opcionais permitidos por essa DA podem não fornecer tempo suficiente para completar todas as instalações de parafusos. A FAA também recebeu relatórios adicionais de corrosão que, em alguns casos, foram mais severos do que o esperado. Como resultado, a FAA determinou que os prazos de conformidade para certas ações devem ser reduzidos. Esta DA proposta exigiria, para certos aviões, a continuidade de certas ações exigidas pela DA 2022-15-01 com prazos de conformidade reduzidos. Para certos aviões, esta DA proposta também exigiria a revisão dos registros de manutenção para determinar se um método correto de aplicação de selante foi utilizado e a execução das ações condicionais aplicáveis. A FAA está propondo esta DA para resolver a condição de segurança inadequada nesses produtos.
The FAA proposes to supersede Airworthiness Directive (AD) 2022-15-01, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2022-15-01 requires inspecting certain vertical fin tension bolt holes; reviewing the bolt sealant application installation procedure in the existing maintenance or inspection program, as applicable; checking maintenance records to determine the replacement status of vertical fin tension bolts; and doing applicable on-condition actions. Since the FAA issued AD 2022-15-01, the FAA has determined that optional sealant types allowed by that AD may not provide sufficient time to complete all bolt installations. The FAA has also received additional reports of corrosion that, in some cases, was more severe than expected. As a result, the FAA has determined that the compliance times for certain actions must be reduced. This proposed AD would, for certain airplanes, continue to require certain actions required by AD 2022-15-01 with reduced compliance times. For certain airplanes, this proposed AD would also require reviewing maintenance records to determine whether a correct sealant application method was used and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2022-15-01, which applies to certain The Boeing Company Model 787-8, 787-9, and 787-10 airplanes. AD 2022-15-01 requires inspecting certain vertical fin tension bolt holes; reviewing the bolt sealant application installation procedure in the existing maintenance or inspection program, as applicable; checking maintenance records to determine the replacement status of vertical fin tension bolts; and doing applicable on-condition actions. Since the FAA issued AD 2022-15-01, the FAA has determined that optional sealant types allowed by that AD may not provide sufficient time to complete all bolt installations. The FAA has also received additional reports of corrosion that, in some cases, was more severe than expected. As a result, the FAA has determined that the compliance times for certain actions must be reduced. This proposed AD would, for certain airplanes, continue to require certain actions required by AD 2022-15-01 with reduced compliance times. For certain airplanes, this proposed AD would also require reviewing maintenance records to determine whether a correct sealant application method was used and performing applicable on-condition actions. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by September 28, 2026.
