Discussion

Advisory Circular 25.869-1 has been prepared to provide guidance on one means of demonstrating compliance with the requirements of § 25.869, “Electrical System Fire and Smoke Protection,” of Title 14, Code of Federal Regulations (CFR). Part 25 contains the airworthiness standards applicable to transport category airplanes.

The means of compliance described in AC 25.869-1 is intended to provide guidance to supplement the engineering and operational judgment that must for the basis of any compliance findings relative to paragraph 25.869(a). This paragraph concerns the protection of electrical systems from fire and smoke.

Harmonization of Standards and Guidance

The AC is based on recommendations submitted to the FAA by the Aviation Rulemaking Advisory Committee (ARAC). We initiated this action under the “Fast Track Harmonization Program” (64 FR 66522, November 26, 1999). The goal of “harmonization tasks,” such as this, is to ensure that:

  • Where possible, standards and guidance do not require domestic and foreign parties to manufacture or operate to different standards for each country involved; and
  • The standards and guidance adopted are mutually acceptable to the FAA and the foreign aviation authorities.

The guidance contained in the AC has been harmonized with that of the JAA, and provides a method of compliance that has been found acceptable to both the FAA and JAA.
