The FAA General Knowledge Exam is the essential foundation for students aiming to become certified as an Aviation Maintenance Technician (AMT), also known as an A&P (Airframe and Powerplant) Mechanic.
It is designed for individuals seeking to pursue a career in aircraft maintenance, repair, and inspection. Passing this test is a mandatory prerequisite before an applicant can take either the Airframe or Powerplant rating exams, and finally the practical test. The exam validates that an aspiring technician has a comprehensive understanding of the core principles common to all aircraft, laying the critical groundwork for advanced maintenance skills.
It is ideal for high school graduates, military veterans transitioning to civilian careers, and anyone passionate about aviation mechanics looking to enter the industry.
This comprehensive knowledge test covers a wide array of fundamental concepts and regulations critical for any aircraft technician. The syllabus encompasses diverse scientific and procedural areas. Students must achieve a solid grasp of aviation-related mathematics and physics, including principles of simple machines, sound, and thermodynamics. A deep understanding of basic electricity is necessary, covering DC and AC circuit theory, magnetism, and electronic components.
Other essential topics include Ground Operations and Servicing procedures like taxiing and securing aircraft. You will learn about key materials, processes, and non-destructive testing methods. A strong emphasis is placed on Weight and Balance calculations for maintaining aircraft safety. The course also details Federal Aviation Regulations (FARs) relevant to maintenance, the proper creation of aviation forms and records, and the interpretation of aircraft drawings and diagrams. Students will be expected to utilize scientific concepts to solve practical aviation problems throughout the test.
The FAA General Knowledge Test is a computerized exam that must be taken in a single, proctored session. It is typically a multiple-choice examination with an emphasis on factual recall and problem-solving based on core concepts. There are no practical hands-on components or essay sections in this specific knowledge test.
A passing score on this exam is 70 percent. The test usually consists of approximately 60 multiple-choice questions, which applicants must complete within a strict two-hour (120-minute) time limit. You will not be permitted to leave the testing room until you have submitted your answers or the time expires. Any specialized tools required, such as a calculator (if permitted by the center) or specific charts for weight and balance, will be provided or must be of a standard type. Applicants must bring appropriate government-issued identification to the testing location.
Effective preparation is key to success on the FAA General Knowledge Exam. Utilizing official FAA study materials is the recommended first step, specifically the relevant volumes of the Aviation Maintenance Technician Handbook—General (e.g., FAA-H-8083-30A), which contain the exact material the questions are based on. Supplementing this with commercial test-preparation software, practice exam databases, and flashcard apps specifically designed for the AMT General test allows students to familiarize themselves with the question format and identify areas needing more study. Many students also choose to enroll in a formal Part 147 aviation maintenance school, which provides structured classroom instruction and lab work that reinforces the theoretical knowledge. Focus heavily on mastering electrical theory calculations, mathematics, and regulations.
The FAA General Knowledge Exam cannot be taken online; it must be administered at an official FAA-authorized Computer Testing Center. These are physical locations, often operated by companies like PSI Services or Pearson VUE, which contract with the FAA to provide secure testing environments. You can locate your nearest authorized center by searching on the PSI or Pearson VUE websites, or on the FAA’s own list of knowledge testing centers. After identifying a convenient location, applicants must pre-register and pay for a specific testing slot directly with the center.
Successfully passing the FAA General Knowledge Exam is the crucial first milestone on the pathway to becoming a fully certified Airframe and Powerplant Mechanic. While this exam alone does not grant certification, it unlocks the ability to proceed with the more specialized Airframe and Powerplant ratings and the final practical examination. Acquiring the full A&P certificate significantly opens doors to high-demand and well-paying career paths. Here are job titles and career avenues that a technician with the full A&P license can explore:
Aircraft Mechanic: General aircraft inspection, troubleshooting, repair, and maintenance for a wide variety of civil aircraft.
Airframe Technician: Specialists focused on repairing and maintaining the aircraft's structural integrity, systems (like hydraulics and landing gear), and external body.
Powerplant Technician: Mechanics specializing in turbine and reciprocating engine overhauls, inspection, and maintenance.
General Aviation Mechanic: Working on small, privately-owned aircraft at local airports or fixed-base operators (FBOs).
Airline Maintenance Mechanic: Employment with major air carriers at base maintenance facilities or at airport terminals conducting line maintenance.
Corporate Aircraft Technician: Providing dedicated maintenance for private jets and corporate flight departments.
Aviation Inspector / Quality Control: Moving into oversight roles with experience to inspect work and ensure compliance with FAA regulations and safety standards.
Aviation Maintenance Instructor: With further experience, teaching the next generation of technicians at aviation maintenance schools.
Component Overhaul Technician: Working in certified repair stations, focusing on specific aircraft components like landing gear, engines, or avionics systems.
Manufacturing Technician: Supporting the final assembly or system installation for aircraft manufacturers.
