If you’re sizing up a career fixing airplanes, the first practical question usually isn’t about pay or prestige.
It’s about time.
How long is AMT school, really, and what does that mean for your job, your rent, and the next two years of your life? Fair question. The honest answer is that most people finish in somewhere between 18 and 24 months full-time, but that range stretches quite a bit depending on the program you pick and how much of your week you can hand over to it.
Let’s walk through it the way a shop foreman would explain it, without the brochure language.
By the end you’ll know exactly how long is AMT school for the path you’re actually considering, not the average across every program in the country.
The Short Answer to How Long Is AMT School
For a full-time student at an FAA-approved Part 147 Aviation Maintenance Technician School, plan on roughly 18 to 24 months to earn both the Airframe and Powerplant ratings. Some accelerated programs push it closer to 10 or 16 months. Some community college programs that bundle in general education courses run closer to two years or a little past.
Part-time and evening tracks typically run 24 to 36 months. Same content, spread thinner across the week. So when someone asks how long is AMT school and gets a one-number answer, they’re getting an incomplete one.
Then there’s testing time on the back end, which most people forget to budget for. More on that in a minute.
What the FAA Actually Requires
Here’s where a lot of the confusion around how long is AMT school comes from. For decades, the rule was simple and rigid: 1,900 hours of instruction for both ratings, 750 for a single rating plus the general section. Schools built their calendars around that number, which is why so many programs landed in that 18 to 24 month window.
In 2022 the FAA rewrote Part 147. The prescriptive hour minimum went away, replaced by a competency-based approach tied to the Airman Certification Standards. Schools now have more freedom to design curricula around demonstrated skill rather than seat time. You can read the current rule text on the FAA’s aviation mechanic page.
What changed in practice? Less than you’d think, at least so far. Most Part 147 schools kept their existing hour structures because their facilities, instructor staffing, and financial aid calendars were already built that way. But a handful have started trimming, and that trend is worth watching if speed matters to you. If you want the full breakdown of how these schools are approved and what that certification means, our guide to Part 147 schools covers it.
Full-Time Programs: How Long Is AMT School If You Go All In
This is the standard path and the one most students take. You’re in the shop or classroom roughly 30 to 40 hours a week, Monday through Friday, often with a schedule that looks a lot like a real maintenance job. Which is intentional.
A typical full-time sequence looks something like this:
- General section, 3 to 5 months. Basic electricity, weight and balance, materials and processes, publications, regulations.
- Airframe section, 6 to 9 months. Sheet metal, composites, hydraulics, landing gear, fuel systems, airframe electrical.
- Powerplant section, 6 to 9 months. Reciprocating and turbine engines, ignition, fuel metering, propellers, lubrication.
Some schools run these back to back. Others interleave them. Either way, the total lands in that same window, which is why full-time is the benchmark most people mean when they ask how long is AMT school. Some schools, like Thrust Institute of Maintenance, run highly accelerated programs that are only 10 months long.
The upside of full-time is momentum. The material builds on itself and you’re not relearning last semester’s wiring diagrams. The downside is obvious: holding a full-time job alongside it is a grind.
Part-Time and Evening Programs: 24 to 36 Months
If you’re supporting a family, holding down a day job, or transitioning out of the military while still on terminal leave, a part-time track is often the only realistic option. And it’s a legitimate one. The certificate you walk away with is identical.
Evening programs usually meet four or five nights a week for three to four hours, sometimes with Saturday lab sessions. That pace stretches how long is AMT school out to roughly two and a half to three years.
Two things to think about before you commit:
Attrition is real. Three years is a long time to keep showing up after a full workday. Ask any school you’re considering what percentage of their evening cohort finishes. If they won’t answer, that tells you something.
Not every school offers it. Evening tracks require duplicate instructor staffing and extended shop hours, which not every campus can afford. In some metro areas you’ll have one option. In others, none. Worth checking early in your search rather than late.
The Community College Route
A number of Part 147 programs live inside community colleges and award an associate degree alongside the A&P eligibility. These usually run the full two years, sometimes a semester longer, because you’re taking English composition and college algebra alongside turbine theory.
If you’re calculating how long is AMT school on this route, add a semester to your mental estimate and don’t be surprised if it’s two.
Is the extra time worth it? Depends on where you’re headed. If you’re aiming for a line mechanic job at a regional carrier or an MRO, the degree adds little in the short term.
If you can see yourself moving into inspection, quality assurance, management, or eventually a Designated Mechanic Examiner role, having a degree already banked saves you from going back later. Tuition at community colleges also tends to be dramatically lower, which factors into the math alongside what AMT school actually costs.
Why the Answer to How Long Is AMT School Varies So Much
Two students can start the same month and finish a year apart. Here’s what drives that:
- Cohort start dates. Some schools enroll every eight weeks. Others start once or twice a year. If you miss a start, you wait.
- Single rating vs. both. You can pursue just Airframe or just Powerplant, which cuts your time roughly in half. Most employers want both, but not all of them do.
- Credit for prior experience. Military maintenance experience, previous coursework, or an existing rating can shorten your program considerably.
- Class size and shop access. If forty students are sharing one engine test cell, projects queue up. Ask about student-to-instructor ratios and how many hands-on hours you’ll actually get.
- Your own attendance. Part 147 schools track attendance closely. Miss too much and you make it up, which extends your finish date.
- Program pacing after the 2022 rule change. A few schools have compressed their calendars under the new competency-based standards. Two campuses in the same state can now give you different answers to how long is AMT school.
Don’t Forget Testing Time When You Calculate How Long Is AMT School
Graduating from a Part 147 program doesn’t hand you a certificate. It makes you eligible to test.
You still have to pass three written exams (General, Airframe, Powerplant), then an oral and practical exam with a Designated Mechanic Examiner for each rating.
Most graduates knock out the writtens within a few weeks of finishing, while the material is fresh. The oral and practical takes scheduling, and DME availability varies by region: two weeks in some markets, a month or more in others.
Budget one to three months between your last day of class and the certificate in your hand. That’s part of the real answer when someone asks how long is AMT school.
The Other Path: 30 Months of Documented Experience
School isn’t the only route. Under 14 CFR 65.77, you can qualify to test based on practical experience: 18 months for a single rating, 30 months working on both airframes and powerplants for the combined ticket. You’ll need documented, verifiable experience and a signed recommendation before the FAA will authorize you to test.
People weighing this option against a classroom usually ask how long is AMT school by comparison.
This path works well for military maintainers and for people already working under supervision at a repair station.
It works poorly for someone starting from zero, because getting hired into a shop that will sign off your time without a certificate is its own uphill climb. Time-wise, it’s usually longer than school, not shorter.
Picking the Timeline That Actually Fits Your Life
Once you know how long is AMT school across your options, the choice gets easier. The fastest program isn’t automatically the best one.
A 14-month accelerated track that leaves you shaky on troubleshooting doesn’t do you any favors on day one at a hangar. Neither does a three-year evening program you burn out of at month twenty.
When you’re comparing schools, ask about total program length in months, start date frequency, hands-on shop hours versus classroom hours, whether evening or weekend options exist, and what happens if you need to step away for a semester.
Ask what their graduates are earning, too, and cross-check it against current aircraft mechanic salary data and the Bureau of Labor Statistics occupational outlook for aircraft mechanics.
One more thing worth saying plainly: this field is open to a lot more people than it used to be, and the schools that have figured that out tend to be the ones with the strongest support systems and the highest completion rates. If you’re wondering whether you’d fit in a hangar, you probably would.
Putting It Together
So, how long is AMT school? Full-time, 18 to 24 months for both ratings, plus one to three months of testing.
Part-time or evening, two and a half to three years. Community college with a degree attached, right around two years or slightly more. Single rating only, roughly half of whichever track you choose.
Those numbers are a starting point, not a promise. The only way to know how long is AMT school at a specific campus is to ask that campus directly, then compare the answer against a few others nearby.
