Resumo da Diretiva
A FAA está revogando a Diretiva de Aeronavegabilidade (DA) 2021-11-15 para certos motores turbofan modelo V2500 da International Aero Engines AG (IAE). A DA 2021-11-15 exigia a realização de inspeção ultrassônica (IUS) do disco do 1º estágio da turbina de alta pressão (TAP) e do disco do 2º estágio da TAP e, dependendo dos resultados das inspeções, a substituição do disco do 1º estágio da TAP ou do disco do 2º estágio da TAP. Desde a emissão da DA 2021-11-15, a FAA determinou a necessidade de esclarecer o prazo de conformidade para inspeção de qualquer disco do 1º estágio da TAP ou disco do 2º estágio da TAP que esteja instalado em um motor de modelo de baixo empuxo, mas que tenha sido previamente operado em um motor de modelo de alto empuxo. Esta DA exige a realização de IUS do disco do 1º estágio da TAP e do disco do 2º estágio da TAP e, dependendo dos resultados das inspeções, a substituição do disco do 1º estágio da TAP ou do disco do 2º estágio da TAP. A FAA está emitindo esta DA para corrigir a condição insegura nestes produtos.
The FAA is superseding Airworthiness Directive (AD) 2021-11-15 for certain International Aero Engines AG (IAE) V2500 model turbofan engines. AD 2021-11-15 required performance of an ultrasonic inspection (USI) of the high-pressure turbine (HPT) 1st-stage disk and HPT 2nd- stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. Since the FAA issued AD 2021-11-15, the FAA determined the need to clarify the compliance time for inspection of any HPT 1st-stage disk or HPT 2nd- stage disk that is installed on a low-thrust model engine but had been previously operated on a high-thrust model engine. This AD requires performance of a USI of the HPT 1st-stage disk and HPT 2nd-stage disk and, depending on the results of the inspections, replacement of the HPT 1st-stage disk or HPT 2nd-stage disk. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
