Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os aviões Bombardier, Inc., Modelo BD-700-2A12. Esta DA foi motivada pela descoberta de que uma perda parcial de empuxo após uma falha de motor durante uma abordagem de autorização de desempenho de navegação requerido (RNP-AR) sob certas condições de peso, altitude e temperatura (WAT) pode levar a uma descida abaixo da orientação de trajeto especificada. Esta DA requer uma revisão do manual de voo do avião (AFM) existente, de modo a incorporar tabelas WAT atualizadas para operações de abordagem RNP-AR. A FAA está emitindo esta DA para resolver a condição insegura nesses produtos.

ENOriginal (Federal Register)

The FAA is adopting a new airworthiness directive (AD) for all Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by the discovery that a partial loss of thrust after an engine failure during a required navigation performance authorization required (RNP- AR) approach under certain weight, altitude and temperature (WAT) conditions, may lead to a descent below the specified path guidance. This AD requires a revision to the existing airplane flight manual (AFM), to incorporate updated WAT tables for RNP-AR approach operations. The FAA is issuing this AD to address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: Background The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Bombardier, Inc., Model BD-700-2A12 airplanes.
