Aircraft Mechanic (A&P) School: The Path to Certification

Airframe and Powerplant

The A&P certificate has two ratings: Airframe (the structure, systems, and controls) and Powerplant (engines and their systems). Most mechanics earn both. The certificate is what legally allows a person to perform and sign off maintenance on certified aircraft.

How You Get Certified

• Approved school or experience: attend an FAA Part 147 school or document qualifying experience.
• Written exams: general, airframe, and powerplant knowledge tests.
• Oral and practical: demonstrating knowledge and hands-on competence to an examiner.
• Ongoing accountability: maintenance sign-offs carry legal weight.

Why the Trade Endures

Demand for certified mechanics is strong and the work is well compensated because it is exacting and safety-critical. Adjacent aviation roles, including drone operations under Part 107, share the same regulatory rigor.

Program Length and Content

Programs cover general, airframe and powerplant subjects across many hours. Attendance and performance requirements apply.

Confirm the school is FAA approved.

Written, Oral and Practical Exams

After school, candidates take written tests and an oral and practical exam with a designated examiner.

Study aircraft records and regulations.

Career Options

Certified mechanics work for airlines, repair stations and general aviation. Experience and specializations can lead to inspection authorization.

Consider working while you study.

Choosing an FAA Approved School

Part 147 schools follow an FAA approved curriculum. Check pass rates, hangar access, tooling and instructor experience.

Ask about placement relationships with airlines and repair stations.

Documentation Discipline

Maintenance records are legal documents, and accuracy is part of the job. Students learn to write clear, complete entries.

A missing signature or wrong entry can ground an aircraft.

What the Certificate Covers

An airframe and powerplant mechanic certificate authorizes the holder to perform and approve maintenance on aircraft structures, systems and engines. It is a federal certificate, and the privileges and limitations are defined by regulation.

The airframe rating covers structures, flight controls, hydraulics, landing gear, environmental systems and related areas. The powerplant rating covers reciprocating and turbine engines, propellers, fuel and ignition systems.

Many mechanics hold both ratings, since most employers expect the combination. Requirements and privileges should be confirmed with the certificating authority rather than assumed.

Routes to Eligibility

The two common routes are completing an approved maintenance technician school or documenting the required practical experience under supervision. Military maintenance experience may also qualify with appropriate documentation.

Approved schools condense the requirement into a structured program covering general, airframe and powerplant subjects with substantial shop time. The experience route takes longer but allows earning while learning.

Whichever route is used, the applicant must be authorized to test, which involves verifying eligibility before the examinations are scheduled.

The Examinations

Certification involves written examinations, an oral examination and a practical examination for each area. The oral and practical are conducted by a designated examiner and cover a broad range of tasks.

Preparation requires more than memorizing question banks. Examiners ask candidates to explain procedures, locate information in maintenance publications and perform tasks correctly.

The ability to find an answer in the appropriate manual is itself a tested skill, because no mechanic is expected to carry every specification in memory.

Documentation and Regulatory Discipline

Maintenance records are legal documents. Entries must accurately describe the work performed, reference the data used and be signed by the person approving the aircraft for return to service.

Using approved data, following the manufacturer instructions and respecting the limits of the certificate are not formalities. Deviations create airworthiness and liability problems that extend well beyond the individual.

Mechanics also need to understand airworthiness directives, service bulletins and how to determine whether a particular action is required or recommended.

Career Paths After Certification

Certified mechanics work for airlines, repair stations, corporate flight departments, general aviation shops, manufacturers and government operations. Each environment has a different pace and different specialization.

Additional authorizations such as inspection authorization open further opportunities, with their own experience and testing requirements.

Specialization in avionics, composites, engines or particular aircraft types often follows, and manufacturer training is a common route into those areas.

Preparing Well

Students who succeed treat the program as a job: consistent attendance, thorough notes, hands on participation and use of publications rather than reliance on instructor summaries.

Simulation and practice environments let students rehearse procedures, inspections and troubleshooting repeatedly without consuming aircraft time or parts, which is particularly valuable for tasks that are hard to arrange in a shop.

Supervised hands on work on real aircraft remains central, and no substitute exists for it in meeting regulatory requirements.

Common Mistakes and How to Avoid Them

Common failures include working from memory instead of current data, incomplete or vague log entries, exceeding the limits of the certificate and returning an aircraft to service before all items are verified.

Supervisors can help by making it acceptable to pause and ask. A culture where questions are treated as competence rather than weakness produces fewer errors in aircraft maintenance.

How Employers Evaluate Readiness

Employers evaluate mechanics on quality of work, documentation accuracy, adherence to procedures and attitude toward reporting discrepancies rather than minimizing them.

Keeping Skills Current

Aircraft types, directives, publications and procedures are updated continuously. Mechanics who work from current revisions rather than remembered ones avoid errors that inspections and audits will find.

Planning and Preparation

Before beginning a task, a mechanic gathers the current maintenance data, confirms the aircraft configuration, assembles the correct tools and parts and verifies that any required inspections or approvals are in place.

Documentation That Holds Up

Maintenance entries must identify the work performed, the data referenced, the parts used, the date and the certificate holder approving return to service.
