Scope
This SAE Aerospace Standard (AS) provides general requirements for components that are used in commercial aircraft hydraulic systems. It also includes the 14 CFR Part 25/CS 25 regulations that apply to hydraulic components.
It also provides information to be included in the Procurement Specification in Appendix A and a checklist for design reviews in Appendix B.
It does not provide requirements for distribution elements such as hoses, pipe fittings and general tubing.
Rationale
The changes to AS4941 at Revision B include:
-
a
Additional technical requirements including removing all references to JAR airworthiness regulations
-
b
Editorial changes including re-organizing some of the sections and updating the references

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.
