Calendar varies by program; not a federal stopwatch
14 CFR 65.77 practical experience
Concurrent airframe and powerplant work
“How long to become an aircraft mechanic” is a clock question with two legal answers. Graduate from an FAA-certificated Part 147 school and you sit the knowledge tests on the school’s paper. Or document practical experience under 14 CFR 65.77: at least 18 months for one rating, or 30 months of concurrent airframe and powerplant work for both. There is no federal shortcut that turns a summer into a certificate. The FAA become-a-mechanic page is the official checklist. This desk is the calendar.
After authorization you still owe the knowledge tests (70% or better) and an oral and practical with a DME. Schools sell a calendar. The FAA sells a standard. Budget both, plus the weeks between a failed O&P and the retake. If you wanted the money clock, that is starting pay and the salary desk. If you wanted the door, stay here.
The two clocks
Part 147 AMTS programs commonly run 12–24 months. That is a school calendar, not a federal stopwatch. Some compress. Some pad. Ask for a 12-month completion rate, not a brochure month-count. The experience path is the regulation: 18 months full-time practical for one rating, 30 months concurrent for both. Part-time stretching of those months is how a FSDO sends you home. Military time is evaluated against the same 65.77 test; it is not a third clock. See military to A&P.
| Path | Typical calendar | What you must bring |
|---|---|---|
| Part 147 AMTS | Often 12–24 months | Graduation / authenticated school document |
| Experience, one rating | ≥ 18 months full-time practical | Logs a FSDO will actually read |
| Experience, A&P | ≥ 30 months concurrent | Airframe and powerplant in the same period |
| Military | Evaluated, not automatic | Tasks, hours, aircraft — then the tests |
The school calendar, without the hoodie
A 147 can be the faster door if you can pay, show up, and pass. It can be the slower door if you enroll in a part-time evening program and then retake a written. Tuition planning often lands in a $20,000–$50,000+ band before housing; we will not invent a named school’s 2026 sticker. Compare clock hours, first-time pass rates, and the public 147 you can drive to. The how to get an A&P desk is the full path. This section is only the months.
Compressed programs still have to cover the work. If a flyer implies a weekend, leave. If a flyer implies “guaranteed job at a major in 12 months,” read job outlook and the starting-pay desk in the same sitting. The school can authorize you to test. It cannot authorize a bid.
18 and 30 are not slogans
Read 65.77. One rating: at least 18 months of practical experience with the procedures, practices, materials, tools, machines, and equipment generally used on that side of the airplane. Both ratings: at least 30 months concurrent. Concurrent means both kinds of work in that period, not two careers taped together. Or graduate from a certificated AMTS. That is the fork. Eligibility still starts at 14 CFR 65.71: 18 years old, English, and the rest of the part.
- Full-time practical experience. Document hours, tasks, aircraft.
- A helper log that cannot name the work is not 18 months.
- Do not add 2018 airframe to 2024 engines and call it 30 months concurrent.
- Military: same standard, different paperwork. Still the tests.
- School graduation replaces the experience clock, not the knowledge and skill tests.
Authorization is not a pass
Once you are authorized, you sit general, airframe, and/or powerplant knowledge tests, then oral and practical. People fail the practical on paperwork and safety. Budget retake windows. Budget the tool box before the DME, not after. A temporary certificate is a legal document. It is not a shift. Count weeks, not vibes, between a fail and a retest.
The FAA mechanic FAQ is the official sequence when this page and a Facebook mnemonic disagree. They will disagree. Take the FAQ.
After the tests: another clock
A temporary certificate is not a shift bid. Airlines and busy 145s still want a type, a city, or a night that hurts. Count 6–18 months after the ticket before the paycheck looks like the brochure. Median pay in May 2025 was $79,870. That is the occupation, not week one. The AMT pay scale is what people mean when they skip this paragraph.
IA is later: both ratings in effect three years, two years actively engaged, then a written. Do not put IA on a how-long-to-become-A&P calendar. GROL is a different agency and a different Saturday. Put them on the calendar only if the cork board names them.
Calendar mistakes that cost a year
A sixth calendar leak is housing. A 12-month 147 in a city you cannot afford becomes an 18-month 147 when you pick up a night job that eats study time. Run rent next to tuition the same week you tour. The best aviation schools conversation is a different hub, but the arithmetic is the same: the quote without housing is a brochure. Add testing fees, a retake, and a month of tools. Then decide if 147 is still faster than 30 months of paid experience.
A seventh leak is waiting for a “perfect” shop before you start an experience log. 65.77 cares that the work is real and documented, not that the hangar was famous. A small GA shop that will let you actually maintain airplanes can beat a 145 that parks you on inventory. Keep the log as you go. Reconstructing 18 months from memory the week of a FSDO appointment is how people lose a year they already worked.
Once you have a realistic end date — school graduation plus tests, or 18/30 plus tests — write the job date on a different line. Those are two clocks. Mixing them is how a catalog says “A&P in 14 months, airline by 16.” The salary median will still be $79,870 whether you finish in 14 months or 30. The loan will not. Pick the door you can finish without lying to a FSDO or to yourself.
If you are coming from another country’s system, add a third clock: translation. Transport Canada time, EASA time, or a military MOS still has to satisfy 65.77 or a 147. Do not put “conversion, one summer” on a calendar unless the current FAA page says that sentence for your exact paper. This desk will not invent it.
- Enrolling in a 147 without asking completion rate and the public alternative.
- Starting an experience log on a napkin and calling it 18 months later.
- Sitting tests before authorization, or letting authorization go stale.
- Planning a life on “one year” because a catalog used that phrase.
- Ignoring that Transport Canada time is a different system if that is your paper.
Pick the door with money and calendar, not with Instagram. Then add the job clock. The Pay desk will still be there when you have a number on a locker.
Can I get an A&P in six months?+
Not under 65.77 experience rules. Some 147 calendars are compressed; they are still a full program plus tests, not a weekend. Read 14 CFR 65.77.
Does part-time work count 1:1?+
The FAA talks in full-time practical experience. Document hours honestly. A FSDO that smells a stretched log will send you home.
How long after A&P until IA?+
Both ratings must have been in effect at least three years, plus two years actively engaged. See how to get IA.
Does military time shorten 147?+
It can satisfy 65.77 instead of 147 if the hours look like the work. It does not skip tests. Military to A&P is the desk.
When does the paycheck catch the brochure?+
Often 6–18 months after the ticket, if you got hired. Median $79,870 is not week one. See starting pay.
