The Role of an Aircraft Maintenance Technician (AMT)

Aircraft Maintenance Technicians, or AMTs, are responsible for maintaining the physical components of an aircraft. Their primary role is to ensure that all mechanical systems, such as engines, landing gear, brakes, and control systems, are functioning properly and meet strict regulatory standards. Some of the tasks AMTs handle include:

• Inspection and diagnosis: Performing routine inspections and identifying potential mechanical issues before they escalate into major problems.
• Repair and replacement: Fixing or replacing damaged or worn-out components such as engine parts, landing gear, tires, and more.
• Preventative maintenance: Following a schedule to maintain aircraft performance, reduce wear and tear, and increase the lifespan of the components.

AMTs work on the physical, mechanical systems of an aircraft, such as:

• Engines (turbine or piston)
• Landing gear
• Hydraulic systems
• Fuel systems
• Airframe structures (wings, fuselage)
• Flight control surfaces (rudder, ailerons, elevators)

Types of Aircraft Maintenance

There are several different types of maintenance that an AMT may be responsible for, depending on their certification and the type of aircraft. These include:

• Line Maintenance: Routine checks that are performed while the aircraft is in active service.
• Base Maintenance: More in-depth maintenance and repairs performed at a maintenance facility.
• Heavy Maintenance: Major overhauls that require extensive work, often taking the aircraft out of service for an extended period.

Certification Requirements for AMTs

In most countries, including the United States, AMTs must hold a certification from aviation regulatory bodies such as the Federal Aviation Administration (FAA). The FAA certifies AMTs under Part 65 of its regulations, requiring candidates to pass both a written and practical exam.

Aero Wave Aviation and Maintenance School ensures that its students receive comprehensive training, preparing them to become FAA-certified AMTs. Our program focuses on hands-on experience with real-world aircraft, making graduates highly qualified for employment in the field.

Overview of Aviation Electronics Technology (AET)

What is Aviation Electronics Technology?

Aviation Electronics Technology (AET), also known as avionics, focuses on the electrical and electronic systems within an aircraft. This field covers a wide range of sophisticated technologies, including navigation systems, communication equipment, radar, and even the control systems that help pilots operate the aircraft safely.

The Role of an Avionics Technician (AET)

Avionics Technicians, or AETs, work specifically with the electronic systems found in modern aircraft. These systems include:

• Navigation Systems: GPS, Instrument Landing Systems (ILS), and other technology that helps pilots navigate.
• Communication Systems: Radios, transponders, and satellite communications equipment that pilots use to communicate with air traffic controllers and ground crews.
• Radar and Surveillance Systems: Equipment used to detect and avoid obstacles, manage air traffic, and monitor weather conditions.
• Electronic Flight Instruments: Displays and controls that provide pilots with crucial information such as altitude, airspeed, and direction.
• Autopilot Systems: Technology that helps maintain aircraft stability and reduces pilot workload during long flights.

Avionics Maintenance

AETs are responsible for diagnosing, repairing, and maintaining the electronic systems that keep the aircraft operational. This requires a deep understanding of electrical principles, as well as specialised knowledge in the various types of equipment found on an aircraft. Key tasks include:

• Calibration: Ensuring that avionics systems are accurate and providing the correct data to the pilot.
• Troubleshooting: Using specialised diagnostic tools to identify problems within the aircraft’s electronic systems.
• Repair and Replacement: Replacing faulty components such as circuit boards, wiring, and other electronic devices.
• Software Updates: Many modern avionics systems rely on software to function, so AETs must also be proficient in performing updates and resolving software-related issues.

Certification Requirements for AETs

Much like AMTs, AETs also require certification to work on commercial aircraft. In the United States, certification is typically regulated by the FCC (Federal Communications Commission) and may also involve specialised endorsements depending on the specific avionics systems a technician is working with.

At Aero Wave Aviation and Maintenance School, we offer a comprehensive Avionics Technology program that trains students to become certified AETs. Our program emphasises both theoretical knowledge and practical experience, ensuring that graduates are well-prepared to enter the workforce.
