Resumo da Diretiva

A FAA propõe adotar uma nova diretiva de aeronavegabilidade (DA) para todos os aviões De Havilland Aircraft of Canada Limited, modelo DHC-8. Esta DA proposta foi motivada por relatos de porcas de cano trincadas na asa de espar frontal e na junta do estabilizador horizontal com o estabilizador vertical. Esta DA proposta exigiria inspeções repetitivas para trincas e corrosão das porcas de cano afetadas e as ações corretivas aplicáveis. A FAA está propondo esta DA para abordar a condição insegura destes produtos.
