So you’re thinking about turning wrenches on airplanes for a living.
Good call.
Aircraft maintenance is one of the most stable, well-paid trades you can pick up without a four-year degree, and the industry has been short on skilled workers for years now.
Fortunately, there isn’t one road into this career. There are three, and the paths to becoming aircraft mechanic vary wildly in cost, time commitment, and lifestyle fit.
The Three Paths to Becoming Aircraft Mechanic Certification
The FAA only cares that you can prove three things before you sit for the Airframe and Powerplant exam: you’re at least 18, you can read, write, and speak English, and you have either the schooling or the experience to back up your application.
How you check those boxes is up to you.
The three paths to becoming aircraft mechanic certification break down like this:
- Part 147 school: An FAA-approved aviation maintenance technician program.
- Military service: Hands-on training under one of the armed forces aviation maintenance ratings.
- OJT (on-the-job training): Documented civilian work experience under FAR 65.77.
Each route gets you to the same place: an A&P certificate in your wallet and the legal authority to work on civilian aircraft.
The differences come down to how long it takes, what it costs you, and what kind of mechanic you’ll be on day one.

Path 1: AMT School (The Part 147 Route)
This is the most common of the paths to becoming aircraft mechanic certified. You enroll in an FAA-approved Part 147 school, knock out the curriculum, then sit for the A&P exam right after graduation.
Most students finish in 12 to 24 months. Some accelerated programs can shave that down further.
What you’ll learn
Part 147 schools cover the general, airframe, and powerplant subject areas the FAA requires.
Aircraft systems, hydraulics, electrical, sheet metal, engines, propellers, inspection procedures, weight and balance, and a hundred other things you didn’t know you needed to know. You’ll spend roughly half your time in a classroom and half in a hangar with actual aircraft.
What it costs
Tuition varies a lot. Community college programs run $15,000 to $25,000 total.
Private aviation institutes can hit $50,000 or more. Don’t forget tools, books, lodging, and the exam fees on top of tuition. Financial aid, GI Bill benefits (if you qualify), and Workforce Innovation and Opportunity Act funding can knock that number down significantly.
Who this path fits
The Part 147 route works well for you if you learn better with structure, want the fastest legal route to your A&P certificate, and don’t mind taking on tuition debt to compress the timeline.
The AMT school vs military debate is a real one, but if speed and a civilian schedule matter most, Part 147 wins.
The downside
You’re paying for the privilege of learning. And while a solid program gets you exam-ready, you’ll still be a green mechanic on day one at a real shop.
The school covers the FAA-required material. It doesn’t cover the muscle memory of doing the same task 200 times under a deadline.
Path 2: The Military Route
If you can handle a few years in uniform, the military is one of the most underrated paths to becoming aircraft mechanic certified.
Every branch trains aviation maintenance personnel, and they pay you while they do it.
- Air Force: 2A career fields (crew chiefs, avionics, propulsion, and more).
- Army: 15-series MOSs (mostly rotary-wing aircraft).
- Navy: AD, AM, AE, and AT ratings.
- Marines: 60xx and 61xx MOSs.
- Coast Guard: AMT rating.
The training is paid. The housing is paid. The medical and dental are paid.
And when you separate or retire, you can document your time and use it to qualify for your A&P exam without spending a dime on Part 147 school. That’s a hard combination to beat.
How the FAA counts military experience
Active-duty and prior military mechanics use FAA Form 8610-2 to document time spent in a qualifying MOS or rating. Your training records and performance evaluations support the application.
Once a Flight Standards District Office (FSDO) inspector signs off, you’re cleared to take the written, oral, and practical exams.
The official FAA guidance for both civilian and military applicants lives in FAA regulations Part 65. Read it. Bookmark it. Refer back to it when you start the application.
Who this path fits
This is the right pick if you’re open to service, want to graduate with zero student debt, and want real-world experience before you ever touch a civilian shop.
Military aircraft mechanics tend to come out fast, organized, and unflappable. Civilian employers know it, and they hire on it.

The downside
It’s a long commitment. Active-duty contracts typically run four to six years. Deployments happen. Family separations happen. And not every military aviation job translates neatly to the civilian A&P.
A pure avionics technician, for instance, may still need to bridge gaps before the FSDO will sign off on both ratings.
And there’s no guarantee you’ll become an aircraft mechanic when you enroll. It can be your preferred job but the military will assign you where they need you.

Path 3: OJT (On-the-Job Training)
The third path to becoming aircraft mechanic certified is the slowest but also the most flexible.
It’s the on-the-job training route, formally laid out in FAR 65.77, and it’s how plenty of mechanics quietly built careers before AMT schools were the default.
How OJT works
To qualify for the A&P exam through experience alone, the FAA requires:
- 18 months of practical experience for the airframe or powerplant rating individually.
- 30 months of practical experience for both ratings combined.
- Documentation showing you actively worked on the relevant systems.
- A signed statement from a supervising A&P or the FSDO confirming your time and the scope of your work.
You’ll find OJT aircraft mechanic positions at general aviation shops, FBOs, regional carriers, and smaller operators willing to take on helpers.
The pay’s usually modest at first. But it’s pay you wouldn’t get in a Part 147 classroom, and it’s experience that money can’t buy.
What to document
Keep a detailed logbook from day one. Every task. Every aircraft. Every hour. Note the tail number when you can, the type of work performed, the systems involved, and who supervised.
Sloppy records sink more OJT applications than weak skills ever do.
Who this path fits
OJT works well for you if you already work in or around aviation (line service, fueling, ramp), have a connection at a shop willing to mentor you, or simply can’t afford tuition and aren’t enlisting.
It can be a grind, but folks have built strong careers as an OJT aircraft mechanic this way, often coming out of it with sharper hands than a fresh AMT graduate.
The downside
It’s the slowest of the three paths to becoming aircraft mechanic certified. It’s also the hardest to start, because shops aren’t always eager to train someone from scratch when they can hire an A&P-rated mechanic instead.
Add in the documentation burden, and you’ve got a route that rewards patience over speed.
How to Choose Among the Paths to Becoming Aircraft Mechanic Certified
You’ve now got the three A&P certification routes laid out. Picking the right one isn’t about which path is objectively “best.” It’s about which one fits your life right now.
Walk yourself through these questions, honestly.
How fast do you need to start earning?
If you need to be working with an A&P in hand within two years, Part 147 is your fastest legal route. Military service takes longer in absolute terms, but you’re paid the entire time.
OJT is the slowest with no fixed finish line, but you will be earning an income while you train\.
What’s your tolerance for debt?
Part 147 schools cost real money. The military pays you. OJT pays you too (but usually less). If avoiding debt is non-negotiable, the military and OJT routes both deserve a hard look.

What’s your lifestyle situation?
If you’ve got a family, a mortgage, or roots you can’t pull up, military service might be off the table. If you’re 19 and unattached, those years of service can build you a lifetime of skills and zero debt.
Part 147 lets you stay where you are. OJT requires finding a local shop willing to mentor.
How do you learn?
Some folks need a classroom and a syllabus to lock things in. Others learn by breaking parts and fixing them under a supervisor’s eye. Be honest with yourself.
Part 147 is structured. Military is structured-with-deployments. OJT is mostly self-directed inside a working shop.
A Word on Hybrid Routes
You don’t have to pick one path and stick with it for life. Plenty of mechanics start in the military, separate, then finish a short Part 147 bridge program to cover gaps.
Plenty of OJT folks eventually enroll in school to speed things up. The paths to becoming aircraft mechanic certified aren’t walls. They’re lanes, and you can change lanes.
The right move at 19 might not be the right move at 35. Career changers especially tend to mix and match among the paths to becoming aircraft mechanic certified.
A former Army crew chief with three kids isn’t going to make the same choice as a high schooler with no obligations and a curiosity about jet engines.
Cost and Timeline at a Glance
Sometimes it helps to see the three paths to becoming aircraft mechanic certification side by side. Here’s the rough math, in plain numbers.
- Part 147 school: 18 to 24 months (though there are schools that do it in as little as 10 months), $15,000 to $50,000+ out of pocket, no income during training (unless you work nights), exam-ready on graduation day.
- Military: 4 to 6 years of service, full pay and benefits the whole time, $0 tuition, plus GI Bill on the back end. Exam eligibility right after separation which does have a cost.
- OJT: 18 months minimum for one rating, 30 months for both, paid (modestly) throughout, no tuition, but no guaranteed timeline.
None of the three paths to becoming aircraft mechanic certification is automatically the smartest call. The smartest call is the one you’ll actually finish.
What All Three Paths Have in Common
Whichever of the paths to becoming aircraft mechanic certified you pick, a few things stay constant. You’ll need to pass the same three FAA exams: the written test, the oral, and the practical. You’ll need to keep learning long after you’ve got the certificate.
And you’ll need to keep your tools, your attitude, and your safety habits sharp.
Aircraft maintenance technicians are professionals.
The certificate is the floor, not the ceiling. The mechanics who climb fastest are the ones who treat every airplane like the people on board are family.
No matter which of the paths to becoming aircraft mechanic certified got you there, that mindset is what employers and inspectors notice first.
Bottom Line
All three paths to becoming aircraft mechanic certified end at the same destination: a Federal Aviation Administration A&P certificate. The certificate itself doesn’t care how you earned it.
Employers care a little, but mostly they care that you can do the work safely, accurately, and on time.
Pick the route that matches your money, your timeline, your lifestyle, and the way you learn.
Then commit fully. The paths to becoming aircraft mechanic certified all reward consistency more than they reward raw talent, so pick the lane you’re most likely to stay in.
The industry needs you, and the doors open the moment you’ve got that ticket in your hand.
