Final answer:
The standard of performance under which the holder of an inspection authorization performs activities is detailed in Part 65 of the Federal Aviation Regulations, particularly 14 CFR Part 65.95.
Step-by-step explanation:
The standards of performance for the holders of inspection authorizations in relation to their activities in the aviation field are outlined in the Federal Aviation Regulations (FARs). Specifically, these standards can be found in Part 65, which covers the certification of airmen other than flight crewmembers, and includes sections that pertain to mechanics with inspection authorizations.
An inspection authorization (IA) is a certification issued by the Federal Aviation Administration (FAA) to qualified mechanics who meet specific experience and testing requirements. This allows them to perform certain advanced inspections and to approve aircraft for return to service following major repairs and alterations. The regulation that details the performance standards for IAs is 14 CFR Part 65.95. This regulation specifies the scope and detail of the inspections that IAs are authorized to conduct as well as the records they must keep.
