What types of repairs can a type rated pilot complete?

A type rated pilot is typically authorized to perform certain light maintenance tasks that do not require extensive technical expertise or extensive disassembly of the aircraft. Among the choices provided, simple fabric patch repairs are within the scope of what a type rated pilot is allowed to do. These repairs are not complex and can usually be completed by someone with basic familiarity with the aircraft's operational aspects, rather than requiring specialized engineering knowledge.

On the other hand, major structural repairs, such as those involving critical components of the airframe, require significant expertise and are heavily regulated. Similarly, engine overhauls are comprehensive and technical processes that must be performed by certified aircraft maintenance engineers due to the high safety standards needed for engine reliability. Replacement of avionics systems involves advanced knowledge of the aircraft’s electronic systems and also typically requires a licensed technician to ensure compliance with safety regulations and certification standards.

Thus, only simple fabric patch repairs align with the competency of a type rated pilot, allowing them to maintain the aircraft at a basic level without venturing into more complicated or regulated maintenance tasks.
