Definition
A person certificated by the FAA to inspect, service, repair, and approve aircraft and aircraft components for return to service, within the limits of their certificate ratings. The two ratings available are Airframe (A) and Powerplant (P), and most certificate holders earn both, commonly referred to as an A&P mechanic.
Plain English
Someone the FAA has officially licensed to work on aircraft. They can fix, inspect, and sign off on the airplane or its engine, depending on which rating they hold.
Context Anchor
Seen in aircraft maintenance records, logbook entries, repair discussions, inspections, and FAA rules about who may perform or approve maintenance.
Derivation
Aviation comes from a Latin word meaning “bird,” later used for flying. Mechanic comes from an old Greek word connected with machines. Together, aviation mechanic means a person who works on the machines used for flight.
Why Pilots Care
Only an aviation mechanic can legally return an aircraft to service after maintenance, directly affecting whether the airplane is airworthy for the next flight.
Intuition Check
Do not read mechanic here as simply “someone who is handy with engines.” In aviation use, an aviation mechanic is someone with the proper FAA certificate and rating for the aircraft work being done.
Example Sentence 1
Before the flight, the owner asked an aviation mechanic with both Airframe and Powerplant ratings to investigate the rough-running engine.
Example Sentence 2
Before the cross-country flight the pilot confirmed the aviation mechanic had cleared the squawk on the alternator.
