Data developed for and incorporated in a supplemental type certificate is considered approved data for major repairs?

• A. Yes
• B. No
• C. Only if approved by FAA
• D. Only for minor repairs

Answer: (A)

Data developed for and incorporated in a supplemental type certificate are FAA-approved data. When the FAA approves an STC, the data package—drawings, procedures, drawings, and limitations used to implement the modification—becomes approved data. That approval covers the way the modification is to be performed, so major repairs that fall within the scope of the STC can rely on that approved data instead of needing new, separate approval. This means you can use the STC data as the authorized basis for major repairs related to the modification, provided you stay within the STC’s limitations and applicable airworthiness requirements.
