Resumo da Diretiva
A FAA está revogando a Diretiva de Aeronavegabilidade (AD) 2021-05-02, que se aplicava a todos os helicópteros Airbus Helicopters Modelo AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C e AS350D; Modelo AS355E, AS355F, AS355F1, AS355F2, AS355N e AS355NP; e Modelo EC130B4 e EC130T2. A AD 2021-05-02 exigia determinar se o helicóptero foi operado em ambiente severo desde a última inspeção dos parafusos de fixação do cubo do rotor principal ao mastro, inspeção dos parafusos de fixação do cubo do rotor principal ao mastro se o helicóptero foi operado em ambiente severo, e substituição dos parafusos de fixação do cubo do rotor principal ao mastro, se necessário, conforme especificado em uma AD da Agência Europeia para a Segurança da Aviação (agora Agência de Segurança da Aviação da União Europeia) (EASA), incorporada por referência. Desde que a FAA emitiu a AD 2021-05-02, os resultados de inspeção relatados e investigação posterior confirmaram que o relato de falha dos parafusos de fixação do cubo do rotor principal ao mastro, que motivou a AD 2021-05-02, foi um caso isolado resultante de um erro de manutenção. Portanto, a FAA determinou que nenhuma condição insegura é provável que exista ou se desenvolva nos parafusos de fixação do cubo do rotor principal ao mastro em outros helicópteros da frota. Consequentemente, a AD 2021-05-02 é revogada.
The FAA is removing Airworthiness Directive (AD) 2021-05-02, which applied to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130B4 and EC130T2 helicopters. AD 2021-05-02 required determining whether the helicopter has been operated in a severe environment since the last inspection of the main rotor hub-to-mast attachment screws, an inspection of the main rotor hub-to-mast attachment screws if the helicopter has been operated in a severe environment, and replacement of the main rotor hub-to-mast attachment screws if necessary, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which was incorporated by reference. Since the FAA issued AD 2021-05- 02, reported inspection results and further investigation have confirmed that the report of failed main rotor hub-to-mast attachment screws, which prompted AD 2021-05-02, was an isolated case which resulted from a maintenance mistake. Therefore, the FAA has determined that no unsafe condition is likely to exist or develop on the main rotor hub-to-mast attachment screws on other helicopters in the fleet. Accordingly, AD 2021-05-02 is removed.Texto Completo da Diretiva

SUMMARY: The FAA is removing Airworthiness Directive (AD) 2021-05-02, which applied to all Airbus Helicopters Model AS350B, AS350BA, AS350B1, AS350B2, AS350B3, AS350C, and AS350D helicopters; Model AS355E, AS355F, AS355F1, AS355F2, AS355N, and AS355NP helicopters; and Model EC130B4 and EC130T2 helicopters. AD 2021-05-02 required determining whether the helicopter has ( printed page 62720) been operated in a severe environment since the last inspection of the main rotor hub-to-mast attachment screws, an inspection of the main rotor hub-to-mast attachment screws if the helicopter has been operated in a severe environment, and replacement of the main rotor hub-to-mast attachment screws if necessary, as specified in a European Aviation Safety Agency (now European Union Aviation Safety Agency) (EASA) AD, which was incorporated by reference. Since the FAA issued AD 2021-05-02, reported inspection results and further investigation have confirmed that the report of failed main rotor hub-to-mast attachment screws, which prompted AD 2021-05-02, was an isolated case which resulted from a maintenance mistake. Therefore, the FAA has determined that no unsafe condition is likely to exist or develop on the main rotor hub-to-mast attachment screws on other helicopters in the fleet. Accordingly, AD 2021-05-02 is removed. DATES: This AD becomes effective November 12, 2021. The FAA must receive comments on this AD by December 27, 2021.
