Who is authorized to make a major repair on an aircraft?

The authorization to make a major repair on an aircraft is held by an airframe mechanic or an Inspection Authorization (IA) holder. This is because major repairs require specialized knowledge and skills to ensure that they are done in compliance with safety regulations and standards set by the Federal Aviation Administration (FAA).

Airframe mechanics are trained and certified to perform maintenance and repairs on the aircraft fuselage, structure, and systems. Those who hold an IA have additional privileges that allow them to conduct inspections and approve major repairs after they are completed, which is critical for maintaining the airworthiness of an aircraft.

The other options do not have the same level of authorization and expertise required for major repairs. For example, while aircraft owners may perform minor maintenance, they are generally not qualified to undertake major repairs unless they possess the appropriate certification. Certified flight instructors focus on training and instruction rather than maintenance and repair, and aerial applicators specialize in agricultural operations, not aircraft maintenance.
