What's the difference between an Airframe and Powerplant Mechanic and an Avionics Technician?

Aircraft maintenance contains many different jobs. Systems and diagnostics become based more on software with the progression of technology. A large body of information is required to maintain all aspects of the airplane. The creation of specialties in mainly powerplant mechanics, airframe, and avionics is the only way to deal with this.

An "A & P" mechanic is a senior engineer, who is trained in airframe and powerplant.

Airframe deals with the physical framework of an airplane such as the wings, wheels, cabin, doors, windows, brakes, heating and cooling systems, outer skin, floors, and lighting. Check, repair and maintenance services are performed by an airframe mechanic. The flight crew may draw attention to a fault or damage that needs to be taken care of, in addition to the standard servicing, based on specific time interval and cycles of use, that the mechanic will perform. The engines and fuel delivery systems are covered specifically by the powerplant. Mechanics, specializing in this area, will receive training in servicing schedules and repairing internal damages to the engines caused by birds and debris.

An avionics mechanic specializes in the electronic and control systems and components of an aircraft. Avionic mechanics, for example, might work with the anti-skid systems, radar, communication, weather radar, automatic pilot systems, "black box" flight records, and anti-collision systems on an airplane. The knowledge of weapons guidance systems and scrambling communications will also be required to become an military avionics technician. An additional radio license may also be required for this.
