Anti-PMA Rhetoric is Wrong; PMA Parts are Valid, Says FAA

The FAA has issued a special bulletin reminding the industry that PMA parts are perfectly valid for use, and that competitors’ rhetoric questioning FAA-approved PMA parts is contrary to FAA technical findings.


The FAA approves the content of an ALS and ICA based upon its review of the substantiating data provided by an applicant. Applicants for PMA or STC parts are required to assess the ICA requirements. A PMA or STC applicant either shows and states that the product’s ICA are still valid with their part installed or provides a supplemental ICA for any differences.

• PMA Holders Remain Responsible for Continued Operational Safety

TC/PC holders, PMA holders, and STC holders are responsible for the Continued Operational Safety (COS) support in accordance with the applicable standards for their parts and products which they have designed and produced.

MARPA has been supporting the PMA community’s COS Obligations by publishing recommended guidance to help companies develop their own COS programs. At this year’s 2008 MARPA Annual Conference (held October 14-16 in Las Vegas), the Association will feature a COS workshop to assist companies in developing FAA-compliant COS programs.
