Resumo da Diretiva
A FAA está revogando a Diretriz de Aeronavegabilidade (AD) 2021-26-11 para todos os motores Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17 e 895-17. A AD 2021-26-11 exigia a substituição da bomba de combustível afetada em pelo menos um motor afetado. Desde que a FAA emitiu a AD 2021-26-11, a FAA determinou que a substituição de todas as bombas de combustível afetadas em todos os motores instalados é necessária para resolver a condição insegura. Esta AD foi motivada por relatos de eventos de motor único causados por contaminação de água, que levaram à corrosão na bomba de combustível resultando em perda de empuxo do motor. Esta AD exige a substituição da bomba de combustível afetada em pelo menos um motor antes de voo adicional e a substituição de todas as bombas de combustível afetadas dentro de um prazo de conformidade especificado. Esta AD também proibiria a instalação de qualquer motor afetado em qualquer aeronave ou qualquer bomba de combustível afetada em qualquer motor, conforme especificado em uma AD da Agência Europeia para a Segurança da Aviação (EASA), que é incorporada por referência (IBR). A FAA está emitindo esta AD para resolver a condição insegura nesses produtos.
The FAA is superseding Airworthiness Directive (AD) 2021-26-11 for all Rolls-Royce Deutschland Ltd. & Co. KG (RRD) Model RB211-Trent 875-17, 877-17, 884-17, 884B-17, 892-17, 892B-17, and 895-17 engines. AD 2021-26-11 required replacing the affected fuel pump on at least one affected engine. Since the FAA issued AD 2021-26-11, the FAA has determined that replacing all affected fuel pumps on all installed engines is necessary to address the unsafe condition. This AD was prompted by reports of single-engine events caused by water contamination, which led to corrosion on the fuel pump that resulted in loss of engine thrust. This AD requires replacing the affected fuel pump on at least one engine before further flight and replacing all affected fuel pumps within a specified compliance time. This AD would also prohibit installing any affected engine onto any airplane or any affected fuel pump onto any engine, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference (IBR). The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
