What Exactly is an Aircraft Maintenance Technician?

An Aircraft Maintenance Technician (AMT’s) refers to an individual who holds an Airframe and/or Powerplant Mechanic certificate issued by the Federal Aviation Administration. Just like pilots there are rules for certification and regulations which must be abided by for use of their certification. AMT’s inspect, perform and supervise maintenance, preventive maintenance, and alteration of aircraft and aircraft systems.

How Does Someone Become An AMT?

The FAA requirements for eligibility for a mechanic certificate include the following:

Be 18 or older; Be able to read, speak, and understand English; Meet the experience or educational requirement; and Pass a set of required tests. The required tests include, first, a set of computerized knowledge tests; these are followed by a practical test, which includes an oral examination.

A person who fulfills the necessary requirements is issued a Mechanic certificate with either an Airframe or Powerplant rating, or both. An Airframe rating allows the AMT to maintain and repair all systems associated with the airframe of the aircraft while a Powerplant rating includes the engines and all associated equipment. It is these ratings which together account for the common practice of referring to mechanics as “A&P’s.”

What Do AMT’s Have To Know

The good news is an A&P certification covers everything from a hot air balloon to a wide body jumbo jet. Students have the opportunity to study several subjects including: electricity, weight and balance, hydraulics, pneumatics, ground operation of aircraft, cleaning and corrosion control, sheet metal, composite, cabin atmosphere control systems, instrument systems, communication and navigation systems, fuel systems, electrical systems, reciprocating and turbine engine theory and repair, cooling systems, exhaust and reverser systems, propellers and auxiliary power units.

Next time you see an Aircraft Maintenance Technician walking around your aircraft, as you wait for take-off, remember they are highly trained professionals who keep our world moving.
