Repair Approval
Section 03: Certification & Approval Types
Definition
The formal authorization to perform a specific repair on a type-certificated product. Repairs are classified as major or minor, with major repairs requiring approved data from an authorized source before the work can be performed. Sources of approved repair data include the TC/STC holder's repair documentation, DER-approved repair designs, FAA-approved repair data, and repair data in the manufacturer's structural repair manual (SRM). The repair must restore the product to at least its original or properly altered condition.
Where This Shows Up
Repair approvals address returning a damaged or degraded product to an airworthy condition. They are distinct from modifications (alterations), which change the type design. The distinction between major and minor repairs follows similar criteria to the major/minor change classification: a major repair is one that might appreciably affect structural strength, performance, or other airworthiness qualities.
