This proposed AC provides guidance for certification of electrical wiring interconnection systems on transport category airplanes in accordance with 14 CFR part 25, subpart H—Electrical Wiring Interconnection Systems (EWIS), and section H25.4 and H25.5 of Appendix H to part 25. The guidance provided in this proposed AC is directed to transport category airplane manufacturers, modifiers, foreign regulatory authorities, FAA transport airplane type certification engineers, designees, and FAA Flight Standards personnel. It is one means, but not the only means, of complying with the part 25 revisions proposed in Notice No. 05-08, entitled “Enhanced Airworthiness Program for Airplane Systems/Fuel Tank Safety (EAPAS/FTS),” published in this same edition of the Federal Register. Issuance of AC 25.17XX is contingent on final adoption of the proposed revisions to part 25.
