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 Sec. 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.

    Issued in Renton, Washington, on June 11, 2001.
Donald L. Riggin,
Acting Manager, Transport Airplane Directorate, Aircraft Certification 
Service.
