FAQs (Frequently Asked Questions)
What is the Aircraft Mechanic License Examination?
The Aircraft Mechanic License Examination is a formal assessment conducted by the national aviation authority to verify that an applicant has the knowledge, skills, and judgment required to maintain, inspect, and repair aircraft safely. It usually includes written tests on theory and regulations, as well as oral and practical examinations that evaluate hands-on competence on airframe, powerplant, and related systems.
Who is eligible to take the Aircraft Mechanic License Examination?
Eligibility requirements vary by country, but most authorities require candidates to be at least 18 years old and to have completed either an approved aviation maintenance training program or a defined number of months of practical experience on aircraft. Applicants must typically present documentary proof of their education or experience, such as school certificates, logbooks, or employer certifications, before being allowed to schedule the exam.
Do I need to graduate from an aviation maintenance school to qualify?
You do not always need to graduate from a maintenance school, but attending an approved aviation maintenance training institution is often the fastest and most structured path. Candidates who do not attend such a school may still qualify by accumulating practical experience under supervision, but they may need more months of documented work. An approved school helps you build both the theoretical knowledge and hands-on skills that the exam will measure.
What subjects are covered in the written examination?
The written examination commonly includes three broad areas: general knowledge, airframe, and powerplant. General topics include basic math, physics, maintenance practices, regulations, documentation, and human factors. Airframe subjects cover structures, materials, hydraulics, landing gear, flight controls, and environmental systems. Powerplant sections focus on reciprocating and turbine engines, fuel, lubrication, ignition systems, and propellers. Some authorities add basic avionics and electrical systems to the required subjects.
What is included in the practical and oral exam?
The practical and oral exam assesses whether you can safely and correctly apply your knowledge in real maintenance tasks. An examiner will ask you to perform typical jobs such as safety wiring, torque application, component removal and installation, inspection for damage, troubleshooting faults, and reading maintenance manuals or wiring diagrams. At the same time, the examiner will ask questions about why you chose certain procedures, what regulations apply, and how you ensure safety and airworthiness.
How can I best prepare for the Aircraft Mechanic License Examination?
Effective preparation combines theory review with hands-on practice. Start by studying official or authority-approved textbooks that cover general, airframe, and powerplant subjects. Make summary notes of key concepts and formulas, and answer as many sample or mock exam questions as possible. In parallel, practice real maintenance tasks under supervision: using tools correctly, reading maintenance documents, and troubleshooting simple defects. Many candidates also enroll in review courses or refresher classes offered by aviation schools or review centers to organize their study schedule.
How long does it usually take to become a licensed aircraft mechanic?
The total time depends on your chosen pathway. If you attend an approved aviation maintenance school, the training program may take around two to three years, after which you can immediately apply for the licensing exams. If you choose the experience-based route, you may need 18 to 36 months or more of documented practical work to qualify, depending on whether you are applying for airframe, powerplant, or a combined license. You should also consider extra time for exam scheduling, possible retakes, and license processing.
What score do I need to pass the examination?
Passing scores vary by authority, but a minimum of about 70 to 75 percent is common for written exams in each subject area. Some systems require passing each module separately, so you cannot compensate for a low score in one subject with a high score in another. The practical and oral exams are usually graded on competence and safety rather than numerical scores. You must demonstrate that you can perform tasks correctly and consistently follow procedures and regulations.
What happens if I fail a part of the exam?
If you fail a section of the exam, you normally have the opportunity to retake only the failed portion within a specified period, as defined by your aviation authority. It is important to review the topics where you struggled, seek additional training, and practice more intensively before attempting the retake. Repeated failures may lead to waiting periods or additional requirements, so it is wise to treat each attempt seriously and use structured preparation methods.
What career opportunities are available after getting my aircraft mechanic license?
After becoming licensed, you can work in several areas of aviation maintenance. Common employers include airlines, maintenance, repair, and overhaul (MRO) organizations, general aviation shops, helicopter operators, and aircraft manufacturers. Roles can range from line maintenance and heavy maintenance to quality control, technical records, and maintenance planning. With experience and further training, you may move into supervisory, inspection, or training positions, and you may later specialize in areas such as avionics, composites, or non-destructive testing.
Can my Aircraft Mechanic License be used in other countries?
Many countries recognize the training standards of major aviation authorities, but licenses are not always directly transferable. If you wish to work abroad, you may need to undergo a validation process, sit for conversion exams, or complete additional modules to meet the new authority’s regulations. It is recommended to check the specific requirements of the country where you plan to work and to keep detailed records of your training, experience, and license status to support any validation or conversion applications.
How important are safety and human factors in the exam and in real work?
Safety and human factors are central themes in both the examination and actual maintenance practice. The exam will test your understanding of safe work habits, error prevention, communication, fatigue management, and proper use of documentation and checklists. In daily work, aviation maintenance is a safety-critical activity where small mistakes can have serious consequences. Developing strong safety awareness, disciplined work habits, and a culture of reporting and continuous improvement is essential for a long and responsible career as a licensed aircraft mechanic.
