Discussion

    The proposed revisions to the advisory circular (AC) provide a 
convenient source of current policies, guidance, and practices for U.S. 
airworthiness certification and acceptance of civil aeronautical 
products imported to the U.S. Since the publication of current AC 21-23 
in 1987, a new format of bilateral aviation agreement, the Bilateral 
Aviation Safety Agreement (BASA), has been established. A BASA consists 
of an Executive Agreement, signed by the Department of State and its 
foreign counterpart, and one or more Implementation Procedures (e.g., 
for airworthiness, maintenance, flight simulators, environmental 
approval) signed by the FAA and its foreign civil aviation counterpart. 
Both a BASA and its predecessor, a Bilateral Airworthiness Agreement 
(BAA), are intended to facilitate reciprocal airworthiness 
certification of civil aeronautical products imported or exported 
between the two signatory countries. Both are based on a high degree of 
mutual confidence in the technical competence and regulatory capability 
of the aviation authority of the exporting country for performing 
aircraft certification functions within the scope of the agreements, 
but a BASA is more flexible, because if allows for later expansion into 
other FAA regulatory disciplines. The FAA's objective in issuing this 
proposed revised AC is to provide guidance on the current procedures 
and requirements for design and airworthiness approvals of aviation 
products imported to the United States, including requirements in BASA 
Implementation Procedures for Airworthiness.
