Harmonization of Standards and Guidance

The proposed AC is based on recommendations submitted to the FAA by the Aviation Rulemaking Advisory Committee (ARAC). The FAA tasked ARAC (63 FR 50954, September 23, 1998) to provide advice and recommendations on “harmonizing” certain sections of part 25 (including § 25.775) with the counterpart standards contained in Joint Aviation Requirements (JAR) 25. The goal of “harmonization tasks,” such as this, is to ensure that:

1. Where possible, standards and guidance do not require domestic and foreign parties to manufacture or operate to different standards for each country involved; and

2. The standards and guidance adopted are mutually acceptable to the FAA and the foreign aviation authorities.

3. The guidance contained in the proposed 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.

Discussion

This proposed AC sets forth acceptable methods of compliance with the provisions of 14 CFR 25.775 dealing with the certification requirements for windows, windshields, and mounting structures. Guidance information is provided for showing compliance with that regulation. Other methods of compliance with the requirements may be acceptable.
