An aircraft owner was provided a list of discrepancies on an aircraft that was not approved for return to service after an annual inspection. Which of the following statements is/are true concerning who may correct the discrepancies?

• A. Only a mechanic with an IA
• B. An appropriately rated mechanic
• C. Any certified repair station
• D. The owner

Answer: (B)

The key idea is that maintenance and repairs on an aircraft must be performed by someone who holds the proper certificated rating for the work. After discrepancies are found, the people who actually correct them must be an appropriately rated mechanic (airframe and/or powerplant as applicable) or an entity that employs such personnel (like a certified repair station). An Inspection Authorization (IA) is required to perform the annual inspection itself, and the owner is not allowed to perform the repairs or sign them off. The statement that best fits this rule focuses on the requirement for the person doing the corrections to have the correct rating. Repair stations can handle the work, but the underlying requirement is the technician performing it must be appropriately rated; this is why an appropriately rated mechanic is the correct answer.
