Resumo da Diretiva
A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para certos aviões da série Boeing Company Model 737-700, -800, -900 e -900ER. Esta DA foi motivada por um relato de excursão de pista causada por perda de frenagem. Uma inspeção constatou que as mangueiras hidráulicas do freio do trem de pouso principal (TPP) direito foram instaladas incorretamente nos limitadores de fluxo, e os fios do transdutor de velocidade da roda do TPP esquerdo também foram invertidos. Esta DA exige uma inspeção visual geral (IVG) das mangueiras hidráulicas de freio do TPP esquerdo e direito para qualquer instalação cruzada, testes operacionais da válvula antitravamento e do transdutor, e ações aplicáveis conforme a condição. A FAA está emitindo esta DA para solucionar a condição insegura nesses produtos.
The FAA is adopting a new airworthiness directive (AD) for certain The Boeing Company Model 737-700, -800, -900, and -900ER series airplanes. This AD was prompted by a report of a runway excursion caused by loss of braking. An inspection found that the right main landing gear (MLG) hydraulic hoses for the brakes were incorrectly installed at the flow limiters, and the left MLG wheel speed transducer wires were also interchanged. This AD requires a general visual inspection (GVI) of the left and right MLG brake hydraulic hoses for any crossed installation, antiskid valve and transducer operational tests, and applicable on-condition actions. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
