The purpose of this SAE Aerospace Recommended Practice (ARP) is to provide guide lines for allowable leakage for in-service aircraft hydraulic components at a nominal 100 °F (38 °C) temperature and to outline the procedure for measuring such leakage. The limits to be applied to any specific aircraft should be adjusted before inclusion in a maintenance manual.
