Scope
The requirements presented in this document cover the design factors which might cause any part of an electrically motor driven fuel pump assembly to act as an ignition source for explosive fuel vapors within the airplane tank.
Rationale
Revision E of this document is a complete rewrite of the previous version. It expands the scope to cover requirements contained in 14CFR 25.981 and FAA AC 25.981-1C for fuel pump safety, focusing on auto ignition prevention and the general requirements of MIL-STD-882. Other topics relating to pump safety due to ignition sources will be covered in a separate ARP. Otherwise, the content of the document has been updated to include thermal safety recommendations for pumps at the assembly and component level.

* 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.
