FAA Airframe and Powerplant Mechanic Certification Practice Test

Eligibility is typically met through one of three paths: 1) Graduation from an FAA-approved Part 147 Aviation Maintenance Technician School (AMTS). 2) At least 18 months of practical experience for each rating (Airframe and Powerplant). 3) A combination of training and experience. For military aviation mechanics, specific experience can be credited toward these requirements. Documentation of experience (e.g., logbook, employer affidavits) is required when applying to take the written exams.

The process involves three sequential phases: 1) Knowledge Tests: Three computer-based written exams (General, Airframe, Powerplant), each with 60-100 questions. 2) Oral Exam: A face-to-face question-and-answer session with an FAA Designated Mechanic Examiner (DME) covering all subject areas. 3) Practical Exam: A hands-on skills demonstration administered by the DME, where you must perform a series of maintenance tasks and inspections on actual aircraft, components, and tools. You must pass all three knowledge tests before proceeding to the oral and practical exams.

The A&P certificate itself does not expire. However, to exercise the privileges of the certificate (i.e., to approve aircraft for return to service), a mechanic must have actively worked on aircraft for at least 6 of the previous 24 months. If this recent experience requirement is not met, you must complete a refresher training course or get additional experience under supervision to regain active status. The certificate is yours for life, but maintaining its active use requires recent relevant activity.

An A&P Mechanic can perform and approve most maintenance, preventive maintenance, and alterations. An Inspector Authorization (IA) is an additional, advanced rating that can be added to an A&P certificate after meeting stringent experience requirements (e.g., actively holding an A&P for at least 3 years). An IA holds the privilege to perform and approve annual inspections, major repairs, and major alterations, and to conduct conformity inspections. The IA must be renewed every 12 months through a renewal process with the FAA.

Yes. The FAA has specific guidelines for crediting military aviation maintenance experience toward the eligibility requirements. You will need to present documentation of your military training and experience (such as your DD Form 214 and military transcripts) to an FAA Flight Standards District Office (FSDO) or a designated written test examiner for evaluation. Many military specialties align closely with FAA requirements, often allowing veterans to qualify for the exams with supplemental training or testing.
