Who may accomplish a major repair on an aircraft found to be unairworthy after an annual inspection?

A major repair on an aircraft found to be unairworthy after an annual inspection must be accomplished by an appropriately rated mechanic. This requirement is based on the regulations set forth by aviation authorities, which stipulate that significant repairs need to be performed by individuals who possess the necessary certifications and training to ensure safety and compliance with the standards of airworthiness.

An appropriately rated mechanic holds a valid A&P (Airframe & Powerplant) certificate issued by the FAA or equivalent authority, which qualifies them to make repairs and alterations on aircraft. This certification includes rigorous training and knowledge of safety protocols, maintenance practices, and regulatory requirements, ensuring that aircraft repairs are carried out correctly and safely.

The other choices do not meet the qualifications necessary to perform major repairs on aircraft. Repair station technicians, while they may have specialized training, typically work under the oversight of a repair station authorization and are not solely accountable in the same way an A&P mechanic is. Non-rated technicians lack the formal certification required to perform major repairs, and licensed pilots, even though they may have extensive knowledge about flying and aircraft operations, are not qualified to conduct major repairs unless they also possess an appropriate mechanic's certificate.
