Resumo da Diretiva
A FAA está adotando uma nova diretiva de aeronavegabilidade (DA) para todos os aviões Air Tractor, Inc., (Air Tractor) Modelos AT-250, AT-300, AT-301, AT-302, AT-400, AT-400A, AT-401, AT-401A, AT-401B, AT-402, AT-402A, AT-402B, AT-501, AT-502, AT-502A, AT-502B, AT-503, AT-503A, AT-504, AT-602, AT-802 e AT-802A. Esta DA foi motivada por relatos de trincas nos suportes de fixação do atuador do tubo de torque do flape que podem causar o desacoplamento do atuador do flape do tubo de torque do flape. Esta DA requer inspeções visuais e de líquido penetrante repetitivas nas soldas do suporte de fixação do atuador do flape para detecção de trincas e substituição caso trincas sejam identificadas. A FAA está emitindo esta DA para abordar a condição insegura nesses produtos.
The FAA is adopting a new airworthiness directive (AD) for all Air Tractor, Inc., (Air Tractor) Models AT-250, AT-300, AT-301, AT-302, AT-400, AT-400A, AT-401, AT-401A, AT-401B, AT-402, AT-402A, AT-402B, AT-501, AT-502, AT-502A, AT-502B, AT-503, AT-503A, AT-504, AT-602, AT- 802, and AT-802A airplanes. This AD was prompted by reports of cracks in the flap torque tube actuator attachment brackets that may cause the flap actuator to detach from the flap torque tube. This AD requires repetitive visual and dye penetrant inspections of the flap actuator attachment bracket welds for cracks and replacement if cracks are identified. The FAA is issuing this AD to address the unsafe condition on these products.Texto Completo da Diretiva
