(b) record the justification of compliance within compliance documents according to the compliance demonstration plan;
(c) perform testing and inspections as necessary in accordance with the compliance demonstration plan;
(d) ensure and record the conformity of the test articles and equipment and ensure that the test specimen conforms to the specifications, drawings, manufacturing processes, construction and assembly means in the design;
(e) ensure that the test and measuring equipment to be used for testing are adequate for testing and appropriately calibrated;
(f) allow the Agency to conduct or participate in any inspections or tests of aircraft in the final or suitably mature design and production configuration that are necessary to determine that the product with the repair design has no feature or characteristic that makes the aircraft unsafe or environmentally incompatible for the intended use;
(g) carry out flight testing, in accordance with the flight conditions for such flight testing specified by the Agency, as necessary in order to determine that the aircraft complies with the applicable detailed technical specifications and the applicable environmental protection requirements.
Before declaring major aircraft repair design compliance, a plan detailing compliance demonstration methods must be established and followed. Justification, testing, and inspections are required. Test articles and equipment conformity must be ensured. EASA may inspect or test the aircraft. Flight testing may be necessary to ensure safety and environmental compatibility.
