Resumo da Diretiva

PT-BRTradução automática

A FAA está adotando uma nova diretiva de aeronavegabilidade (AD) para determinados aviões Airbus SAS modelo A330-223, -223F, -243, -243F, -321, -322, -323, -341, -342 e -343. Esta AD foi motivada por relatos de ocorrências de flutuação de empuxo durante o procedimento de descida com o sistema automático de aceleração (ATHR) ativo. Esta AD exige a modificação da programação de pinos dos computadores do sistema de orientação do envelope de voo (FMGEC) para ativar a função N1 do ATHR. A FAA está emitindo esta AD para abordar a condição não segura destes produtos.
