Guidance for Certification of Military and Special Mission Modifications and Equipment for Commercial Derivative Aircraft (CDA)
This advisory circular (AC) provides guidance for the certification of commercial derivative aircraft (CDA). CDA are aircraft that have been modified with specialized equipment to perform military and other non-civil missions. CDA are operated-by, or under the operational control of, governmental entities. With certain limited exceptions, they are operated as public aircraft. This advisory circular (AC) sets forth acceptable means, but not the only means, to show compliance to the provisions of Title 14 of the Code of Federal Regulations (14 CFR) parts 23, 25, 27, and 29 regarding type certification requirements for commercial derivative aircraft (CDA). This AC is presented as companion material to the procedures outlined in Order 8110.101, Type Certification Procedures for Military Commercial Derivative Aircraft.” The guidance provided in this AC is for use on certification projects for Military CDA. Certain provisions of this AC may also be applicable to certification projects for non-military CDA e.g., aircraft operated by state or local governments under public-use or aircraft owned by a foreign government.
