External Hydraulic Leakage for In-Service Components
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.
This standard has been primarily revised to identify additional components whose external leakage requirements are outside the scope of this document. In addition, there are some additional technical clarifications, the document has been reformatted and some editorial changes have been made.
