You may comment on the proposed Certification Policy Notice listed in this notice by sending such written data, views, or arguments to the above listed address. You may also examine comments received on the proposed Certification Policy Notice, before and after the comment closing date, in Room 815, FAA Headquarters Building, 800 Independence Avenue, SW., Washington, DC 20591, weekdays except Federal holidays, between 8:30 a.m. and 4:30 p.m. The Director of the Aircraft Certification Service will consider all communications received by the closing date before issuing the final Certification Policy Notice.
We typically issue STCs that permit installation on any aircraft of a specific type and model designation. Aircraft compatibility is addressed by the following limitation: “The installer is responsible for determining the compatibility of this STC with other previously approved modifications.” Nevertheless there have been installations made on inappropriate aircraft. These inappropriate installations could have been prevented if STC approvals were restricted to a specified baseline aircraft configuration that includes details of the STC physical and functional interfaces with the prototype aircraft.
Applicant's installation drawings or other installation instructions have not always been detailed enough for accurate replication of the design. This is especially true when follow-on STC installations occur at facilities other than that used by the STC holder for the prototype installation.
The STC certification process does not adequately address how to evaluate the compatibility of an STC with other previously installed STCs, major alterations or repairs. We need a more rigorous compatibility evaluation for certain STCs. This proposed policy ensures that the modified aircraft will be airworthy.
