Which statement about minor alterations is true for certificated mechanics who performed them?

• A. False
• B. Only if supervised
• C. Appropriately to the ratings they hold
• D. Only for major alterations

Answer: (C)

The key idea is that certificated mechanics may perform minor alterations only within the scope of the ratings they hold. That means a mechanic with an appropriate rating (airframe or powerplant, or both, as applicable) may carry out minor alterations as long as the work follows approved data and regulatory requirements. This limits the alterations to what their certificate authorizes; they can’t perform tasks outside their rating or beyond approved procedures. So the statement that is true is that minor alterations must be performed appropriately to the ratings they hold. The other options either misstate the need for supervision or constrain the work to major alterations, which isn’t correct for minor alterations within a mechanic’s authorized scope.
