Resumo da Diretiva
A FAA propõe cancelar a Diretiva de Aeronavegabilidade (DA) 2022-23-08, que se aplica a todos os aviões Viking Air Limited (Viking) Modelo DHC-3. A DA 2022-23-08 requer uma inspeção visual do atuador do estabilizador para confirmar que o anel de travamento do atuador do estabilizador está presente, corretamente assentado no sulco da carcaça superior e travado na porca de pressão, as ações corretivas aplicáveis, aplicação de um lacre de torque e envio dos resultados da inspeção à FAA. Esta DA proposta exigiria inspeções repetitivas do atuador do estabilizador para confirmar que o anel de travamento do atuador do estabilizador está presente, corretamente assentado no sulco da carcaça superior e travado na porca de pressão; execução das ações corretivas aplicáveis; aplicação de uma marca testemunha (lacre de torque); e instalação de um dispositivo de retenção secundário como ação de encerramento das inspeções repetitivas. Esta DA proposta também proibiria a instalação de qualquer atuador de estabilizador, a menos que seja uma peça em condição de serviço. A FAA está propondo esta DA para corrigir a condição insegura nestes produtos.
The FAA proposes to supersede Airworthiness Directive (AD) 2022-23-08, which applies to all Viking Air Limited (Viking) Model DHC- 3 airplanes. AD 2022-23-08 requires a visual inspection of the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, applicable corrective actions, application of a torque seal, and sending the inspection results to the FAA. This proposed AD would require repetitively inspecting the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut; taking applicable corrective actions; applying a witness mark (torque seal); and installing a secondary retention feature as terminating action for the repetitive inspections. This proposed AD would also prohibit the installation of any stabilizer actuator unless it is a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.Texto Completo da Diretiva

ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2022-23-08, which applies to all Viking Air Limited (Viking) Model DHC-3 airplanes. AD 2022-23-08 requires a visual inspection of the stabilizer actuator to confirm that the stabilizer ( printed page 26229) actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, applicable corrective actions, application of a torque seal, and sending the inspection results to the FAA. This proposed AD would require repetitively inspecting the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut; taking applicable corrective actions; applying a witness mark (torque seal); and installing a secondary retention feature as terminating action for the repetitive inspections. This proposed AD would also prohibit the installation of any stabilizer actuator unless it is a serviceable part. The FAA is proposing this AD to address the unsafe condition on these products.
