What Is an AMT? Aviation Maintenance Technician Explained
You'll see the terms "AMT," "aircraft mechanic," "A&P mechanic," and "aviation maintenance technician" used interchangeably in job postings and conversations. They mostly refer to the same thing — but there are some nuances worth understanding.
AMT Defined
An Aviation Maintenance Technician (AMT) is any person who performs maintenance, preventive maintenance, or alterations on aircraft. In FAA terminology, the formal credential is the "Mechanic Certificate" with Airframe and/or Powerplant ratings (the A&P). The Bureau of Labor Statistics (BLS) uses "Aircraft and Avionics Equipment Mechanics and Technicians" as their occupational category.
"AMT" is the industry's preferred professional term — it's used by:
- The FAA in Advisory Circulars and training curricula
- Part 147 schools (Aviation Maintenance Technician Schools)
- Professional organizations (PAMA — Professional Aviation Maintenance Association)
- FAA handbooks (FAA-H-8083-30A is the "Aviation Maintenance Technician Handbook — General")
AMT vs. A&P: What's the Difference?
| Term | Meaning |
|---|---|
| AMT | Broad professional title for aviation maintenance workers |
| A&P Mechanic | Specific FAA certificate holder (Airframe & Powerplant) |
| Aircraft Mechanic | Common shorthand for A&P mechanic |
| Aviation Technician | General term; may include avionics techs |
In practice, when an employer posts a job for an "AMT" or "Aircraft Mechanic," they almost always require an FAA A&P certificate. The terms are functionally interchangeable in hiring.
What AMTs Do Daily
The daily work of an AMT varies by employer and specialization, but a typical day might include:
At an Airline (Line Maintenance):
At an MRO (Heavy Maintenance):
In General Aviation:
Who Hires AMTs?
| Employer Type | Estimated Number of AMTs Employed |
|---|---|
| Airlines (Part 121) | ~45,000 |
| MROs (Part 145) | ~30,000 |
| General Aviation (FBOs, Part 91) | ~25,000 |
| Corporate Aviation | ~15,000 |
| Military/Defense | ~20,000 (civilian A&Ps) |
| OEMs (Boeing, Airbus, Textron, etc.) | ~15,000 |
| Government (FAA, other agencies) | ~5,000 |
Total estimated U.S. AMT workforce: ~155,000–165,000
AMT Job Outlook
The BLS projects 6% growth for aircraft mechanics through 2032, which is about average for all occupations. However, the actual demand is significantly higher due to:
- Aging workforce (many AMTs retiring in the 2020s–2030s)
- Fleet growth globally
- Increasing aircraft complexity requiring more maintenance hours
- Fewer military-to-civilian pipeline entrants than in past decades
The mechanic shortage is real and growing. Airlines and MROs are offering signing bonuses, relocation packages, and higher starting wages to attract AMTs.
