Approved Data

Section 03: Certification & Approval Types

Definition

Technical data (engineering drawings, repair procedures, modification instructions, test results) that has been reviewed and formally approved by the certifying authority or an authorized delegate (DER, ODA, DOA). Approved data carries the full weight of regulatory authorization and may be used as the basis for manufacturing, modifying, or repairing type-certificated products. Examples of approved data include TC/STC design data, DER-approved repair data, PMA design data, and manufacturer's repair manuals approved under the TC.

Where This Shows Up

The distinction between approved data and acceptable data is important for maintenance and modification work. Major repairs and major alterations require approved data. Minor repairs and minor alterations may use either approved data or acceptable data.
