Parts Manufacturer Approval (PMA) - Design Approval
The design approval phase of PMA certifies that a replacement or modification part complies with the airworthiness standards of eligible products (aircraft, engine or propeller). The applicant shows this compliance through tests and computations unless the part is identical to the part design on a type-certificated product. Identicality means that a part is the same in all respects to a part design in a type-certificated product. Evidence of license agreement shows this identicality.
