Resumo da Diretiva
A FAA está revogando a Diretiva de Aeronavegabilidade (AD) 2021-22-20, que se aplicava a determinados motores diesel alternativos modelo E4 e E4P da Austro Engine GmbH. A AD 2021-22-20 exigia, para motores com uma culata de cilindro afetada, inspeção da engrenagem de comando da bomba de alta pressão (HPP) e, dependendo dos resultados da inspeção, substituição da engrenagem de comando da HPP por uma peça elegível para instalação. A AD 2021-22-20 também exigia, para motores com uma engrenagem de comando da HPP afetada, substituição da engrenagem de comando da HPP antes do voo adicional ou dentro de um número determinado de horas de voo, dependendo da configuração do motor e do número de motores afetados instalados. Esta AD exige, para motores equipados com uma combinação específica de culata de cilindro e engrenagem de comando da HPP, remoção, inspeção e substituição da engrenagem de comando da HPP antes do voo adicional e, dependendo dos achados da inspeção, substituição do eixo da HPP, culata de cilindro, engrenagem de comando variável ou bucha de comando variável de entrada/saída. Esta AD também exige, para motores com uma engrenagem de comando da HPP afetada, substituição da engrenagem de comando da HPP antes do voo adicional ou dentro de um número determinado de horas de voo, dependendo da configuração do motor e do número de motores afetados instalados. Esta AD foi motivada por relatos de falha da engrenagem de comando da HPP e pela determinação subsequente de que um lote de engrenagens de comando da HPP pode ter sido danificado durante a montagem. Esta AD também foi motivada por uma investigação que constatou que determinadas culatas de cilindro instaladas em combinação com determinadas engrenagens de comando da HPP no mesmo motor podem causar dano à engrenagem de comando da HPP. A FAA está emitindo esta AD para resolver a condição insegura nesses produtos.
The FAA is superseding Airworthiness Directive (AD) 2021-22-20 which applied to certain Austro Engine GmbH E4 and E4P model diesel piston engines. AD 2021-22-20 required, for engines with an affected cylinder head, inspection of the high pressure pump (HPP) driving gear and, depending on the results of the inspection, replacement of the HPP driving gear with a part eligible for installation. AD 2021-22-20 also required, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD requires, for engines equipped with a certain cylinder head and HPP driving gear combination, removal, inspection, and replacement of the HPP driving gear before further flight and, depending on the inspection findings, replacement of the HPP shaft, cylinder head, camshaft gear, or inlet/outlet camshaft bushing. This AD also requires, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD was prompted by reports of failure of the HPP driving gear and a subsequent determination that a batch of HPP driving gears may have been damaged during assembly. This AD was also prompted by an investigation which found that certain cylinder heads installed in combination with certain HPP driving gear on the same engine may cause damage to the HPP driving gear. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva

ACTION: Final rule; request for comments. SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-22-20 which applied to certain Austro Engine GmbH E4 and E4P model diesel piston engines. AD 2021-22-20 required, for engines with an affected cylinder head, inspection of the high pressure pump (HPP) driving gear and, depending on the results of the inspection, replacement of the HPP driving gear with a part eligible for installation. AD 2021-22-20 also required, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD requires, for engines equipped with a certain cylinder head and HPP driving gear combination, removal, inspection, and replacement of the HPP driving gear before further flight and, depending on the inspection findings, replacement of the HPP shaft, cylinder head, camshaft gear, or inlet/outlet camshaft bushing. This AD also requires, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD was prompted by reports of failure of the HPP driving gear and a subsequent determination that a batch of HPP driving gears may have been damaged during assembly. This AD was also prompted by an investigation which found that certain cylinder heads installed in combination with certain HPP driving gear on the same engine may cause damage to the HPP driving gear. The FAA is issuing this AD to address the unsafe condition on these products. DATES: This AD is effective February 14, 2022.
