What does an Aircraft Mechanic do?

An aircraft mechanic typically does the following:

  • Examines aircraft frames and parts for defects
  • Diagnoses mechanical or electrical problems
  • Measures parts for wear, using precision instruments
  • Reads maintenance manuals to identify methods of repair
  • Repairs wings, brakes, electrical systems, and other aircraft components
  • Replaces defective parts, using hand tools
  • Tests aircraft parts with gauges and other diagnostic equipment
  • Inspects completed work to ensure that it meets performance standards
  • Keeps records of maintenance and repair work

Today’s airplanes are highly complex machines that require reliable parts and service to fly safely. To keep an airplane in peak operating condition, aircraft mechanics do scheduled maintenance, make repairs, and complete inspections.

Some aircraft mechanics work on many different types of aircraft, such as jets, propeller-driven airplanes, and helicopters. Others specialize in one section of a particular type of aircraft, such as the engine, hydraulics, or electrical system of a jet. In smaller independent repair shops, mechanics inspect and repair various types of aircraft.

Most aircraft mechanics who work on civilian aircraft have some sort of official certification. Mechanics that have this certification are authorized to work on any part of the aircraft except electronic flight instruments, which is the job of avionics technicians.

How to become an Aircraft Mechanic

Most aircraft mechanics and technicians learn their trade in a federally approved training program. Coursework normally lasts 18 to 24 months and provides training with the tools and equipment used on the job. About one-third of the programs award two- or four-year degrees in avionics, aviation technology, or aviation maintenance management.

Increasingly, employers are looking more favourably on aircraft mechanics with a bachelor’s degree. Aircraft trade schools are placing more emphasis on technologies being used in new airplanes, such as turbine engines, composite materials, and aviation electronics. These technical advances require aircraft mechanics to have stronger backgrounds in composite materials and electronics.

Courses in mathematics, physics, chemical engineering, electronics, computer science, and mechanical drawings are helpful because they teach the principles involved in operating an airplane. Aircraft mechanics often need this knowledge to figure out what is wrong and how to fix the problem. Courses that develop writing, communication, and management skills are important for aircraft mechanics who want to move into senior positions.
