What would be the general effect of this proposed policy?

The FAA is presenting this information as a set of guidelines suitable for use. However, we do not intend for this proposed policy to become a binding norm; it does not form a new regulation, and the FAA would not apply or rely on it as a regulation.

The FAA Aircraft Certification Offices (ACO's) and Flight Standards District Offices (FSDO's) that certify changes in type design and approve alterations in normal, utility, and acrobatic category airplanes should try to follow this policy when appropriate. In addition, as with all advisory material, this statement of policy identifies one means, but not the only means, of compliance.

Because this proposed general statement of policy only announces what the FAA seeks to establish as policy to encourage use, the FAA considers it an issue for which public comment is appropriate. Therefore, the FAA requests comments on the following proposed general statement of policy relevant to use of the AML STC process for installation approval of MFD's.


You may download a copy from the FAA web site at <​certification/​aircraft/​small _airplane_ directorate_news_proposed.html>, or request a copy by contacting the person named above under FOR FURTHER INFORMATION CONTACT.

This proposed policy statement does not introduce new policy or regulation but provides a compilation of existing regulation, guidance and procedures in the application of the AML STC process for certification projects. This policy focuses on the use of the AML STC for installation of MFD's in Civil Air Regulations (CAR) 3 or of the Federal Aviation Regulations (14 CFR) part 23 airplanes or sailplanes, balloons, or airships operating under part 91, and/or part 135 rules. The AML STC process may be used whenever the ACO and applicant agree that it is appropriate. The AML STC process may also be effective for a certification project of an aircraft under another certification basis. The applicant should coordinate with the appropriate ACO for final determination.
