Resumo da Diretiva
A FAA propõe adotar uma nova Diretiva de Aeronavegabilidade (DA) para certos helicópteros Airbus Helicopters modelo AS350B2. Esta DA proposta foi motivada por um relatório de magnetização nas válvulas solenoides para os três servo-controles principais, o bloco regulador e o servo-controle da cauda devido a um diodo não devidamente instalado no circuito hidráulico. Esta DA proposta exigiria realizar um teste de corte da válvula do atuador do rotor traseiro e, dependendo dos resultados do teste, esta DA exigiria a execução de ações corretivas. A FAA está propondo esta DA para abordar a condição insegura nestes produtos.
The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Helicopters Model AS350B2 helicopters. This proposed AD was prompted by a report of magnetization on the solenoid valves for the three main servo-controls, the regulator block, and the tail servo- control due to a diode not properly installed in the hydraulic circuit. This proposed AD would require performing a cut-off test of the rear rotor actuator valve and depending on the results of the test, this AD would require performing corrective actions. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
