The requirements presented in this document address the key considerations for thermal 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: ARP594 and ARP6385 form a basis for proper safety design of electric, motor driven fuel pumps. Revision F of ARP594 upgrades selected topics with additional design details that have already been included in ARP6385. These revisions are necessary to maintain consistency between the two documents. ARP594, when used in combination with ARP6385 and ARP5794 represents a basis for the proper pump design and testing, and support certification of an airframe fuel pump installation.
