Aircraft Maintenance Technician Job Description

An Aircraft Maintenance Technician keeps aircraft airworthy and legally releasable. Every shift runs the same loop: figure out what is wrong, fix it with approved data, prove the fix works, and write it up so the next technician, the inspector and the FAA can see exactly what happened. The wrench work matters, but so does the signature, because a certificated mechanic who approves an aircraft for return to service is vouching for it personally.

The setting shapes the day. At an airline line station, the work is squeezed into the hours when aircraft sit on the ground. A night shift might open with a stack of pilot write-ups: a cargo door that will not latch cleanly, an air-conditioning pack that ran hot, a brake wear pin close to its limit. Each item gets diagnosed and repaired, or legally deferred under the carrier's minimum equipment list, before the first departure of the morning. Much of it happens outdoors, on stands at the wingtip or under an open engine cowl with a flashlight in one hand.

Heavy maintenance moves at a different pace. In a hangar check, an aircraft is opened up for days or weeks. Panels come off, seats and carpets come out, and crews work through hundreds of task cards covering structural inspections, corrosion treatment, component changes and functional tests. A finding outside manual limits goes to engineering for a repair disposition; the technician then performs the repair and closes the card.

Beyond the airlines, technicians work at FAA-certificated repair stations that overhaul engines, landing gear and components; at business-aviation shops that look after jets and turboprops for corporate flight departments and charter operators; at manufacturers preparing new aircraft for delivery; and in general aviation, where one mechanic may handle everything on a piston single from an oil change to an annual inspection.

The reference library is the same in kind everywhere. The aircraft maintenance manual sets procedures and limits, the illustrated parts catalog pins down the right part number, wiring diagrams trace circuits, and the structural repair manual governs sheet-metal work. Airworthiness directives issued by the FAA are mandatory, and manufacturer service bulletins describe recommended inspections and modifications. Good technicians treat the manual as the authority even when experience whispers that a shortcut exists.

Tools run from safety-wire pliers, torque wrenches and cable tensiometers to borescopes, eddy current probes and laptops that pull fault codes from onboard maintenance computers. Certain tasks, including nondestructive testing, engine runs and taxiing, call for added training and a specific employer authorization on top of the FAA certificate.

Paperwork closes every job. Each task ends with a record entry that describes the work, names the approved data used, and identifies who performed and who approved it. A missing or sloppy entry can keep an aircraft on the ground just as surely as a cracked bracket, which is why experienced mechanics write their entries before they put the tools away.

The entry credential is the FAA mechanic certificate, issued under 14 CFR Part 65 Subpart D with an Airframe rating, a Powerplant rating, or both; the trade calls the combination an A&P. To be eligible, an applicant must be at least 18 years of age, be able to read, write, speak and understand English, and pass all of the prescribed tests within a period of 24 months. The order is fixed: the written knowledge tests come first, and each section must be passed before the applicant can take the oral and practical tests.

School is the main route in. GAO reported that in 2025 nearly seven of 10 new aircraft mechanics obtained their certificate after training at a certificated school, and approximately 20 percent through on-the-job training in the civilian workforce. Students at a certificated school do not have to wait for graduation to start testing: once they present an authenticated document showing they completed the general curriculum, they may take the general written test early.

The rules for those schools were rewritten in 2022. The FAA's Aviation Maintenance Technician Schools rule, issued as an interim final rule, was published May 24, 2022 and took effect September 21, 2022, with two of its amendatory instructions effective August 1, 2023. It adopted new certification and operating requirements for Part 147 schools to conform with the Aircraft Certification, Safety, and Accountability Act. Under the current rule, each school must keep a curriculum designed to continually align with the mechanic Airman Certification Standards, the same standards examiners test against.

A typical path, as guidance:

• Before training: a high school diploma or equivalent, with math, physics and shop classes useful preparation.
• Training: a Part 147 program, or documented experience at a repair station, airline or military unit, followed by the FAA tests.
• First years: line or hangar work under experienced leads, adding employer authorizations for engine runs, taxi, specific aircraft types and individual NDT methods.
• Typically 3 to 5 years in: eligibility for the FAA Inspection Authorization, plus moves into lead, inspector or maintenance control roles.

Other credentials worth knowing:

• FAA Mechanic Certificate with Airframe and Powerplant ratings (Federal Aviation Administration)
• Inspection Authorization (Federal Aviation Administration)
• Repairman Certificate (Federal Aviation Administration)

Personal traits matter as much as the paperwork. The work rewards patience with procedures, comfort at height and in tight spaces, steady hands with small fasteners, and the willingness to stop and ask when a step does not match the manual. Strong written English helps, since every job ends in a record entry someone else must be able to follow. Technicians also need to explain a fault clearly to a pilot or a maintenance controller at three in the morning.

O*NET classifies projected growth for aircraft mechanics and service technicians from 2025 to 2035 as faster than average (5% to 6%), with about 11,400 openings a year on average.

The certificate pipeline has grown quickly. GAO reported that 331,000 individuals held FAA-issued mechanic certificates in calendar year 2025, and that the number of mechanic certificates FAA issued each year nearly doubled, from approximately 5,900 in 2016 to more than 11,100 in 2025. The headline count overstates the working pool: FAA does not track how many certificated mechanics actually work in aviation maintenance, or whether they have moved to other industries. GAO also noted that federal and aviation industry stakeholders have expressed concern about the industry's capacity to meet projected workforce needs because of retirements, attrition and growing demand for air travel.

Where the jobs sit matters for pay and lifestyle. BLS data for May 2025 put 42,580 of these workers in support activities for air transportation, the NAICS industry group that includes third-party aircraft maintenance and repair services, at a median wage of $72,910. Scheduled airlines employed 29,480, and aerospace product and parts manufacturers employed 24,910 at a median of $82,720. For a technician weighing offers, the choice among those sectors shapes the aircraft types, the shift pattern and the kind of work that fills a career.

Federal policy is pushing on the supply side. The FAA Reauthorization Act of 2024, signed into law on May 16, 2024, expanded an existing workforce development grant program for aviation maintenance technical careers and provides for up to $20 million in annual appropriations for it through FY2028. That figure is an authorization, so actual grant dollars depend on yearly appropriations.

Technology is reaching the inspection side of the job. Aviation Week reported in March 2025 that the FAA had authorized United Airlines to use drones for conditional inspections, and that Delta's FAA acceptance covers drone-based inspections in the hangar and outdoors at its maintenance bases in Atlanta, Detroit and Minneapolis. Removing panels, changing parts and signing the record remain hands-on tasks for certificated people.

The career ladder is well defined. From the hangar floor, technicians move into lead and crew chief roles, inspection and quality assurance, maintenance control, planning, technical records, reliability and technical training. Some go to work for manufacturers as field service representatives, and some join the FAA as aviation safety inspectors. Each step leans on the same foundation: a clean certificate history, broad hands-on time across aircraft systems, and a reputation for paperwork that holds up under audit. Technicians who add an Inspection Authorization, gain experience on current-generation engines, or pick up NDT methods give themselves more ways to move when a base closes or a fleet type retires.

Dear Hiring Manager,

I am applying for the Aircraft Maintenance Technician opening on your overnight line crew. I hold an FAA mechanic certificate with Airframe and Powerplant ratings and have spent the past five years working Airbus A320-family aircraft, first in a heavy-check hangar and for the last two years on a busy line station.

The hangar years taught me structure. I worked through C-check task cards on landing gear, cargo compartments and wing-to-body fairings, and I learned how to write a nonroutine card that engineering can act on without a phone call. I also earned my employer's eddy current authorization and performed the bolt-hole inspections our program required.

Line work taught me speed without shortcuts. On a typical night I clear six to ten write-ups across several tails, coordinate with maintenance control on deferrals, and make sure every logbook entry names the manual reference before the aircraft goes back on the schedule. One example: an aircraft kept returning with an intermittent bleed fault that cleared on every ground test. I pulled the fault history from the onboard maintenance system, noticed it only appeared after long cruise legs, and traced it to a chafed sensor harness behind a clamp that only shifted under thermal expansion. Replacing the clamp and repairing the harness ended the repeat write-ups.

I am drawn to your operation because you are adding widebody flying at this station, and I want to earn engine run and taxi authorizations on a new type. I keep a clean record, I am comfortable on nights and holidays, and I will bring the same discipline to your paperwork that I bring to the aircraft.

Thank you for considering my application.

Sincerely, Jordan Reyes
