Aerospace – Definition, Recognition, Troubleshooting And Repair of Commercial Aircraft Hydraulic System Leakage
This ARP provides a comprehensive and consistent set of guidelines for the definition, recognition,
troubleshooting and repair of hydraulic components and systems on in-service commercial aircraft
affected by external leakage.
Rationale: Commercial Aircraft Maintenance personnel continue having difficulties adequately addressing hydraulic system leakage on their aircraft. Existing documentation is scattered between AMM, CMM, and various Trouble-Shooting manuals. Information presented in these documents often provides unclear or inconsistent definitions, and has insufficient detail for identifying and trouble-shooting leakage issues.
