Exam overview and details

The FAA Airframe and Powerplant (A&P) Mechanic Certification is the foundational and mandatory credential for aviation maintenance professionals in the United States. Issued by the Federal Aviation Administration (FAA), it legally authorizes holders to perform maintenance, preventive maintenance, alterations, and inspections on U.S.-registered civil aircraft. Earning this certification requires candidates to demonstrate comprehensive knowledge and practical skills across two distinct ratings: Airframe (covering structures, systems, and components) and Powerplant (covering engines, propellers, and related systems). The certification process involves passing three rigorous written knowledge exams, an oral examination, and a practical skills demonstration, all aligned with 14 CFR Part 147 standards. Possession of an A&P license is not merely a recommendation but a federal requirement for most hands-on maintenance roles, signifying a mechanic's commitment to safety, regulatory compliance, and technical excellence. It is universally recognized as the gold standard for aviation maintenance technicians, opening doors to careers with airlines, repair stations, corporate aviation, and government agencies.

Exam insights and study advice

This certification is the single most important credential for career advancement in aviation maintenance. It is a non-negotiable prerequisite for signing off on aircraft airworthiness and performing critical maintenance tasks. Holding an A&P license dramatically increases earning potential, job security, and professional mobility within the global aviation industry. It signifies to employers a proven, federally-vetted level of competency and a deep understanding of FAA regulations and safety protocols. Beyond entry-level positions, it is the essential stepping stone to roles such as Inspector Authorization (IA), lead mechanic, maintenance controller, and management positions. In a highly regulated industry where safety is paramount, the A&P certification is the definitive mark of a qualified professional.
