Resumo da Diretiva
A FAA propõe substituir a Diretriz de Aeronavegabilidade (DA) 2022-25-05, que se aplica a certos aviões Airbus Canada Limited Partnership Modelos BD-500-1A10 e BD-500-1A11. A DA 2022-25-05 exige limpeza e lubrificação repetitivas de todas as trilhas de slat para prevenir danos ou corrosão; execução de inspeções repetitivas das trilhas de slat para qualquer dano ou corrosão e a aplicação correta de lubrificante; e ações corretivas aplicáveis. Desde que a FAA emitiu a DA 2022-25-05, foi descoberto que reparos anteriores de trilhas de slat exigiam o uso de métodos inapropriados de ensaio não destrutivo (END) e, portanto, podem ter permitido que trincas permanecessem não detectadas em trilhas de slat previamente reparadas. Esta DA proposta continuaria exigindo as ações da DA 2022-25-05 e exigiria uma inspeção END de retrabalhamento em todas as trilhas de slat previamente reparadas utilizando um método END inapropriado. A FAA está propondo esta DA para abordar a condição insegura nestes produtos.
The FAA proposes to supersede Airworthiness Directive (AD) 2022-25-05, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2022-25-05 requires repetitive cleaning and greasing of all slat tracks to prevent damage or corrosion; doing repetitive inspections of the slat tracks for any damage or corrosion, and the correct application of grease; and applicable corrective actions. Since the FAA issued AD 2022-25-05, it has been discovered that previous slat track repairs required the use of inappropriate non-destructive test (NDT) methods and, therefore, may have allowed cracks to remain undetected on slat tracks that were previously repaired. This proposed AD would continue to require the actions in AD 2022-25-05 and would require a rework NDT inspection on all slat tracks previously repaired using an inappropriate NDT method. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
