Scope
This Aerospace Recommended Practice (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 to have difficulties adequately addressing external hydraulic leakage on aircraft. The reason is thought to be that the instructions to identify, troubleshoot, and determine acceptance of external leakage are scattered between the Aircraft Maintenance Manual (AMM), the Component Maintenance Manual (CMM), Troubleshooting Manuals (TSMs), etc., and which often provide insufficient details and unclear definitions to address these issues.
To overcome these difficulties, this document has been generated to provide a comprehensive and consistent set of guidelines for identification, troubleshooting, and rectification of external hydraulic systems leakage.

Issuing Committee
A-6A1 Commercial Aircraft Committee
The Commercial Aircraft Panel is responsible for the development of standards and recommended practices related to the integration of fluid power and actuation technologies into commercial air vehicles. The Panel provides a forum for aircraft manufacturers, suppliers, airworthiness regulatory engineers and operators to exchange technical information and discuss regulatory updates, recent technology developments, lessons learned, and issues related to system development and in service operation.

* Redlines comparisons are available for those standards
listed in the Revision History that contain a radio button. A
redline comparison of the current version against a revision is
accomplished by selecting the radio button next to the standard and
then selecting 'compare'. At this time, Redline versions only exist
for some AMS standards. SAE will continue to add redline versioning
with ongoing updates to SAE MOBILUS.
