Aircraft Fuel Pump Mechanical and Electrical Safety Design
The requirements presented in this document address the key considerations for mechanical and electrical safety in aircraft fuel pump design. Document sections focus on understanding safety relative to an electrically motor driven fuel pump assembly acting as an ignition source for explosive fuel vapors within the airplane tank.
Rationale: This document is a continuation of the safety information presented in ARP594, which covered the thermal aspects of fuel pump safety design. Other failure modes in FAA AC 25.981-1C fall under the umbrellas of mechanical and electrical design. This new document will address these key elements and when used in combination with ARP594 and ARP5794, will represent a basis for the proper pump design and testing, and support certification of an airframe fuel pump installation.
