Integrate bulletin recommendations into your maintenance and repair workflow, documenting any updates to procedures, torque specifications, or replacement part numbers. Maintain a log of bulletin dates and actions taken to ensure traceability and compliance with the latest manufacturer guidance. For shops, establish a systematic process to disseminate critical bulletins to technicians and to archive related work orders, ensuring that all active units operate under up-to-date repair standards and safety practices.
