Understanding A and P Mechanic Licenses: What They Are and Why They Matter

An A and P (Airframe and Powerplant) mechanic license is a federal credential issued by the Federal Aviation Administration (FAA) that certifies a person has met specific training and testing requirements to work on aircraft. The "A" stands for airframe, which refers to the structure of the aircraft including the fuselage, wings, and landing gear. The "P" stands for powerplant, which includes the engines and related systems that provide thrust. Some mechanics obtain both ratings together, while others pursue them separately.

The FAA created these licenses to ensure that people working on aircraft have demonstrated knowledge of safety procedures, mechanical systems, and repair techniques. Aircraft maintenance is critical for public safety, which is why the FAA has strict standards. According to FAA data, there are approximately 300,000 certificated mechanics in the United States. The demand for qualified A and P mechanics remains steady, with the Bureau of Labor Statistics reporting that aircraft maintenance technicians earned a median annual wage of around $64,000 as of recent data, with some positions paying considerably more based on experience and specialization.

The license itself is not just a piece of paper—it represents documented competency in a highly specialized field. Employers throughout the aviation industry, including airlines, repair stations, manufacturers, and the military, recognize this credential. When you hold an A and P license, you can legally perform maintenance, repair, and inspection work on aircraft, subject to certain limitations and regulations. Understanding what this license covers and what it requires is the first step in exploring this career path.

Practical takeaway: An A and P mechanic license is a federal FAA certification that shows you have training and knowledge to work on aircraft structures and engines. This credential is recognized across the aviation industry and is necessary for most aircraft maintenance positions.

The Path to Obtaining Your A and P License: Training Requirements Explained

There are two primary pathways to obtain an A and P license: attending an FAA-approved Part 147 school or gaining hands-on experience as an apprentice in an FAA-certified facility. Each path has different time requirements and learning structures.

The first pathway involves enrolling in an FAA-approved aviation maintenance technician school. These programs are sometimes called Part 147 schools because they operate under FAA regulation Part 147. A typical program lasts 18 to 24 months of full-time study and covers both airframe and powerplant systems. Students learn through classroom instruction, laboratory work, and supervised practical training. The curriculum includes topics like aircraft structures, hydraulic systems, electrical systems, engines, fuel systems, and maintenance procedures. Schools must meet strict FAA standards for instructors, facilities, and curriculum content. According to industry sources, there are over 170 FAA-approved Part 147 schools across the United States, ranging from community colleges to private technical schools.

The second pathway is the on-the-job training route. Under this method, you work in an FAA-certified maintenance facility while accumulating the required hours. For an airframe rating, you need 3,000 hours of hands-on experience. For a powerplant rating, you also need 3,000 hours. If you pursue both ratings simultaneously, you need 5,000 hours total. This pathway typically takes longer than attending a formal school—usually 3 to 5 years—but allows you to earn money while learning. Many people combine both pathways, attending a Part 147 school and then gaining additional hands-on experience.

Regardless of which pathway you choose, you must meet certain prerequisites. You need to be at least 18 years old and have a high school diploma or equivalent. You must be able to read, write, speak, and understand English. The FAA also requires that you demonstrate good moral character. Some positions may require a background check or security clearance, particularly if you work on military or government aircraft.

Practical takeaway: You can obtain an A and P license through either formal school training (18-24 months) or on-the-job experience (3-5 years), or a combination of both. The school pathway is faster but requires tuition; the experience pathway takes longer but provides income during training.

Written, Oral, and Practical Tests: What to Expect on Exam Day

After completing your training through whichever pathway you choose, you must pass three tests administered by the FAA to receive your license. These tests are designed to verify that you have the knowledge and skills necessary to work safely on aircraft. Understanding what each test covers can help you prepare effectively.

The first test is the written knowledge exam. For the airframe rating, you take one written test covering topics like aircraft structures, aircraft systems, aircraft maintenance, and general knowledge. For the powerplant rating, you take another written test covering engines, engine systems, engine maintenance, and related subjects. Each written test consists of multiple-choice questions. You have unlimited time to complete the exam, and you may use certain reference materials. The FAA publishes study guides and practice questions for both tests. Many test-takers study with books, online resources, and study groups. You must score at least 70 percent to pass.

The second test is the oral exam, also called the oral and practical test or O&P test. This is conducted one-on-one with an FAA examiner called a Designee. The examiner asks you questions about topics from the written test and observes whether you can explain concepts clearly and demonstrate understanding. The examiner may ask you about regulations, maintenance procedures, troubleshooting methods, and safety practices. This test assesses your ability to communicate technical knowledge and think through problems. The oral portion typically lasts several hours and covers a wide range of material.

The third test is the practical exam, which occurs during the same session as the oral exam. During the practical portion, the examiner may ask you to identify components, explain how to perform specific maintenance tasks, or demonstrate your understanding of procedures. You might be shown actual aircraft parts or systems and asked to identify them or explain how they work. This test verifies that you can apply your knowledge to real aircraft maintenance situations. Performance on all three tests—written, oral, and practical—determines whether you receive your license.

Practical takeaway: You must pass a written exam (70 percent minimum), an oral exam, and a practical exam to get your A and P license. You can prepare using FAA study guides and practice materials, and the exams assess both your knowledge and your ability to apply it to real aircraft work.

Costs, Funding Options, and Financial Considerations

The cost of obtaining an A and P license varies significantly depending on which pathway you choose and which school or program you attend. Understanding the financial aspects helps you plan and explore options that may work for your situation.

For the formal school pathway, tuition typically ranges from $15,000 to $50,000 for an 18 to 24-month program, depending on the school's location, reputation, and facilities. Community colleges generally charge lower tuition than private technical schools. Some schools offer programs that cost less, while others may cost more. In addition to tuition, you may need to budget for books, tools, materials, housing, and transportation. Many students estimate total out-of-pocket costs between $20,000 and $60,000 when including all expenses.

Several funding sources may help offset these costs. The Federal Pell Grant program provides grant money to students who meet income requirements—grants you do not have to repay. Federal student loans, including Direct Subsidized and Unsubsidized loans, allow you to borrow money for education with fixed interest rates. Some schools participate in Federal Work-Study programs, which allow you to work part-time at the school while studying. Many employers in the aviation industry offer tuition reimbursement programs if you work for them while attending school or agree to work for them after graduation. The GI Bill may cover education costs if you are a military veteran or active-duty service member. Some states offer grant programs or workforce development funds for technical training in high-demand fields.

For the on-the-job training pathway, you typically receive a wage while learning, which offsets some costs. However, wages for entry-level aircraft maintenance positions are usually lower than wages for experienced mechanics. You may earn between $25,000 and $35,000 annually while accumulating the required hours. This pathway requires patience and commitment but provides income during the training period.

The FAA testing fees themselves are modest—usually between $200 and $300 total for all three exams (
