sections Sec. Sec. 25.1701 through 25.1739 and sections H25.4 and H25.5 
of Appendix H to part 25. This proposed AC complements revisions to the 
airworthiness standards that are being proposed by a separate notice. 
This notice is necessary to give all interested persons an opportunity 
to present their views on the proposed AC.

DATES: Comments must be received on or before December 5, 2005.

Discussion

    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.

    Issued in Washington, DC, on September 22, 2005.
John J. Hickey,
Director, Aircraft Certification Service.
