At an airline or a big repair station, you're not judged on how well you know one airplane. You're judged on how fast you can find the right page, fix the fault or defer it legally, and hand the jet back on time. Learn the systems and the paperwork of transport-category turbine aircraft first, and the rest of your skills will stack on top.
| Certificate | Best for | Effort | Worth it? |
|---|---|---|---|
| FAA Mechanic Certificate with Airframe and Powerplant ratings (A&P) | Anyone who wants to sign for work on an airline or repair station jet in the US | Most of a couple of years at an approved school, or longer through documented experience | Required for nearly every aircraft mechanic posting at a carrier. Get it before you worry about anything else on this page. |
| FAA Inspection Authorization (IA) | A&P holders who might move into general aviation or charter shops | A few years holding the A&P, then a written test and ongoing renewal | Less useful at an airline, where inspection authority comes from the carrier's own program. Worth it only if smaller aircraft are in your plans. |
| FCC General Radiotelephone Operator License | Mechanics who lean toward avionics and radio troubleshooting | A few weekends of study for the written exams | Some avionics-heavy postings ask for it. If you like wiring and radios, it's cheap and quick to add. |
Eligibility and testing rules get revised, so check the FAA and FCC websites directly before you plan your study.
Responsible for maintenance on commercial aircraft.
Line mechanic on A320 and 737NG fleets: cleared 300+ pilot write-ups using the FIM and MEL, run-up qualified, with a 98% on-time release rate across 18 months of night shifts.
Yes, especially regionals and heavy maintenance repair stations. They expect you to hold your A&P and to learn their fleet through their own training, so show you can read manuals and work systems, not that you already know their airplane.
Heavy maintenance teaches you more systems faster, because the airplane is opened up. Line work sharpens your troubleshooting and deferral judgment under time pressure. A lot of mechanics start in the hangar and move to the line.
Usually a personal set of hand tools, yes. Employers normally supply the calibrated torque wrenches, test sets and specialty tooling, and many post a required tool list, so ask for it before your first day.
Borescope work. It's in demand on every turbine fleet, you can get hands-on time quickly, and a lead will trust you with it well before run-up or RII authority.
