What Are the Requirements to Become an Aircraft Mechanic?

US Aviation Academy

To become an aircraft mechanic, you must be at least 18 years old, able to read, write, speak, and understand English, and either graduate from an FAA-approved Aviation Maintenance Technician School (Part 147 school) by completing the required curriculum hours (typically 1,900 hours), or document 18 months of practical experience for a single rating (Airframe OR Powerplant) or 30 months of practical experience for both ratings combined.

While typically completed after meeting experience requirements, students in FAA-approved schools may take the General knowledge test earlier; ultimately, you must pass three FAA knowledge tests (General, Airframe, and Powerplant), followed by oral and practical examinations

These requirements, established under 14 CFR Part 65 Subpart D, ensure all aircraft mechanics possess the fundamental knowledge, skills, and abilities necessary to maintain aircraft safely and meet FAA safety standards.

Unlike some careers with informal on-the-job training, aviation maintenance demands rigorous certification because mechanics' work directly impacts flight safety, making FAA oversight and standardized requirements essential to protecting public safety.

 

At US Aviation Academy, our FAA-approved A&P training program fulfills the education requirement while preparing you comprehensively for all FAA certification exams, streamlining your path to becoming a fully certified aircraft mechanic in as little as 8-16 months.

What Are the Basic Eligibility Requirements?

The basic eligibility requirements to become an aircraft mechanic include being at least 18 years old at the time of completing certification testing, possessing the ability to read, write, speak, and understand the English language fluently enough to comprehend technical manuals and communicate effectively about maintenance issues, and having either a high school diploma or GED (while not legally required by FAA, most employers and training schools require this). These fundamental prerequisites ensure mechanics can safely perform maintenance tasks, understand technical documentation written in English, communicate clearly about safety-critical issues, and possess the basic educational foundation needed to comprehend complex aviation systems and regulations.

Age Requirement:

FAA Minimum Age:

  • Must be 18 years old to receive an FAA mechanic certificate
  • Can begin training earlier (16-17 years old) at Part 147 schools

  • Background checks standard in aviation

Accommodations:

  • Disabilities that don't impact safety-critical work can be accommodated
  • Consult with local FAA Flight Standards District Office (FSDO) if concerns
  • Many mechanics work successfully with corrected vision, hearing aids, etc.

What Training or Experience Is Required?

To qualify for FAA mechanic certification testing, you must meet one of two pathways: either complete an FAA-approved Aviation Maintenance Technician School (AMTS) program certified under 14 CFR Part 147 which typically takes 18-24 months and covers all required subjects through structured curriculum, OR document practical experience working on aircraft gaining 18 months of hands-on experience for a single rating (either Airframe or Powerplant) or 30 months of experience working concurrently on both to qualify for the complete A&P certificate. The Part 147 school route is most common and provides structured, efficient training with clear qualification upon graduation, while the experience pathway requires meticulous documentation and FAA review before being authorized to test.

Pathway 1: FAA-Approved Aviation Maintenance Technician School (Most Common):

What Is a Part 147 School?

  • Aviation Maintenance Technician School (AMTS) certified by FAA under 14 CFR Part 147
  • Must meet strict FAA standards for curriculum, facilities, equipment, instructors
  • Over 200 certificated Part 147 schools nationwide
  • Provide structured training meeting all FAA requirements
  • Graduation certificate provides eligibility to test for mechanic certificate

Curriculum Requirements:

Three Main Sections:

  • General: Foundational knowledge required for all mechanics (mathematics, physics, regulations, basic skills)
  • Airframe: Aircraft structure and associated systems, excluding the repair or alteration of instruments and propellers
  • Powerplant: Aircraft engines and propulsion systems

Training Components:

  • Classroom instruction on theory and principles
  • Hands-on laboratory work on actual aircraft and components
  • Practical exercises performing maintenance tasks
  • Safety training and procedures
  • FAA regulations and compliance
  • Documentation and record-keeping

Program Duration:

  • Traditional programs: 18-24 months full-time
  • Accelerated programs: 8-16 months (intensive schedule)
  • Part-time/evening programs: 24-36 months
  • Depends on ratings pursued: Single rating faster than A&P

Upon Graduation:

  • School issues Certificate of Completion
  • Document proves eligibility to take FAA tests
  • Must meet all other requirements (age, English)
  • Can immediately schedule FAA knowledge tests

Advantages of Part 147 Route:

  • Structured, efficient path to certification
  • Comprehensive training on all required subjects
  • Clear eligibility upon completion
  • Networking with classmates and instructors
  • Often includes job placement assistance
  • Faster than experience-only route typically
  • May qualify for financial aid or VA benefits

Pathway 2: Practical Experience (Alternative Route):

Experience Requirements:

  • Single rating (Airframe OR Powerplant): Minimum 18 months practical experience
  • Both ratings (A&P): Minimum 30 months concurrent experience
  • “Practical experience” means: Actually performing maintenance work, not just observing
  • Must be documented: Extensive records required for FAA review

How to Gain Qualifying Experience:

  • Work under supervision of certificated A&P mechanic
  • Employment at Part 145 repair station
  • Military aviation maintenance experience
  • Aircraft manufacturer employment
  • General aviation maintenance facility
  • Must cover broad range of maintenance topics (see Part 147 Appendices B, C, D)

Documentation Requirements:

Must Provide Evidence of:

  • Time periods worked (dates, hours)
  • Types of work performed
  • Aircraft worked on
  • Systems and components maintained
  • Tools and equipment used
  • Procedures followed

Acceptable Documentation:

  • Employer letters on company letterhead
  • Personal logbooks detailing work
  • Pay stubs showing employment period
  • Work orders and maintenance records
  • Training certificates
  • Supervisor statements
  • Military service records

FAA Review Process:

  • Submit documentation to local FAA Flight Standards District Office (FSDO)
  • FAA Aviation Safety Inspector (ASI) reviews evidence
  • ASI determines if experience qualifies
  • Must demonstrate experience in required percentage of subjects
  • If approved, receive authorization to test (FAA Form 8610-2)
  • Process can take weeks to months

Challenges of Experience Route:

  • Requires finding employment without certification
  • Must work under supervision initially
  • Takes longer than school (18-30 months minimum)
  • Extensive documentation burden
  • No guarantee FAA will accept experience
  • May have gaps in knowledge compared to formal training
  • Must study independently for knowledge tests

Military Experience:

Joint Service Aviation Maintenance Technician Certification Council (JSAMTCC):

  • Program allowing military-trained technicians to get civilian A&P
  • Recognized military training can count toward experience
  • Still must meet testing requirements
  • Documentation through military service records
  • Many A&P schools offer accelerated programs for veterans

Combination Approaches:

Some mechanics combine pathways:

  • Gain some experience, then attend school to fill gaps
  • Complete partial school training, supplement with experience
  • Military training plus civilian school
  • Part 147 school for one rating, experience for second rating

What Tests Must You Pass?

To earn an FAA mechanic certificate, you must pass three knowledge (written) tests covering General, Airframe, and Powerplant subjects with a minimum score of 70% on each exam, followed by oral and practical examinations with a Designated Mechanic Examiner (DME) who assesses your hands-on abilities and understanding through questioning and performance of actual maintenance tasks.
