This guidance is a product of the Aging Non-Structural Systems Plan. The FAA developed the Aging NonStructural Systems Plan to address recommendations of the White House Commission on Aviation Safety and Security (WHCSS). That commission recommended that, in cooperation with airlines and manufacturers, the FAA’s Aging Aircraft Program should be expanded to cover nonstructural systems. The commission was concerned that existing directives, procedures, quality assurance, and inspections may not be sufficient to prevent safety-related problems caused by corrosion and other deteriorating effects on nonstructural components of commercial aircraft as they age. To fully address the WHCSS recommendations on aging systems, we E:\FR\FM\06OCN2.SGM 06OCN2

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

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.
