They must identify aircraft structural parts, control surfaces, landing gear, and composite construction methods. Practical skills include fabricating parts, applying corrosion-preventive compounds, and completing airworthiness directives.
Flight control systems—including cables, pulleys, hydraulics, and actuators—are examined both theoretically and practically. Candidates perform rigging checks, measure control surface deflection, and troubleshoot unresponsive movement. Understanding how structural deformation, component wear, and proper balancing affect aircraft safety is essential. A&P mechanics must apply this knowledge to maintain airframe integrity.
Certification also includes powerplant mounting, cowling removal, and structural inspections around engine installations. Mechanics must know torque values, bolt types, safety wire techniques, and vibration dampening methods. Proficiency in these areas underpins safe aircraft operation and regulatory compliance.
Powerplant Systems & Components
The second major domain is powerplant systems and components. Aircraft & Powerplant Certification requires deep knowledge of engine types—reciprocating, turboprop, turbine—and their systems, including ignition, lubrication, cooling, fuel, and induction. Candidates must interpret maintenance manuals, schematics, and torque limits as well as recognize service bulletins and TBO (time between overhaul) schedules.
A&P mechanics also learn to perform engine inspections, compression checks, magneto timing, and spark plug maintenance. Understanding exhaust systems, turbochargers, superchargers, and governor adjustments is critical for engine performance. Candidates must troubleshoot malfunctions through borescope inspections, oil analysis, and vibration trend monitoring.
Exam preparation includes hands‑on work with engines: installing, aligning, leak checks, and functional testing. Knowledge of instrumentation—oil pressure gauges, tachometers, manifold pressure systems—is required. Mechanics must be able to document inspections, issue maintenance releases, and comply with sheet metal and engine specifications.
General Aircraft Maintenance Practices & Regulations
Aircraft & Powerplant Certification exam also covers general maintenance practices and regulations. Candidates must be familiar with FAA regulations (Title 14 CFR Parts 43 and 65) and how they apply to maintenance, repair, alterations, and recordkeeping. They learn proper use of technical orders, service letters, airworthiness directives, and maintenance manuals.
Good technical documentation practices—using FAA forms 337, 8130‑3, and logbooks—are core skills. Mechanics must know inspection intervals, recurring action criteria, MEL (minimum equipment list), and AD compliance verification. Human factors are also part of this domain, teaching mechanics to reduce errors, report fatigue, and follow proper maintenance culture.
Maintaining regulatory flow—from scheduled inspections to unscheduled troubleshooting—requires clear communication between inspectors, location maintenance personnel, and regulatory authorities. This domain ensures that certified mechanics consistently uphold airworthiness and safety.
Aircraft Inspection Procedures & Documentation
Inspection procedures and documentation form another key domain of the Aircraft & Powerplant Certification exam. A&P candidates must perform detailed airframe inspections—annual, progressive, 100-hour, and preflight checks—with checklist accuracy and methodical processes. They must identify discrepancies such as corrosion, fatigue cracks, and fluid leaks, and estimate repair severity and prioritization.
During powerplant inspections, mechanics evaluate oil consumption, compression readings, accessory wear, and exhaust condition. Understanding how to report findings, complete log entries, and determine return-to-service instructions is vital. Certification demands clarity and precision in documentation to facilitate audits and maintain traceable repair history.
Candidates also demonstrate competence in preparing compliance reports for ADs and SBs and ensuring maintenance actions align with safety standards and service bulletins. This domain ensures accountability, traceability, and informed decision-making for aircraft status.
Safety & Human Factors in Maintenance
Safety and human factors make up a critical domain examined by the Aircraft & Powerplant Certification process. Mechanics face occupational hazards such as confined space work, sharp edges, electrical systems, and engine exposure. Certification emphasizes safe work practices: lockout/tagout procedures, proper tool usage, and adherence to personal protective equipment standards.
Human factor education covers shift work, fatigue management, communication protocols, and team coordination. Recognizing how errors occur and developing mitigation strategies (like peer review and break implementation) are essential for reducing aviation incidents.
Candidates also review accident case studies to analyze maintenance root causes—like improper inspection or poor communication—and propose procedural improvements. This domain ensures certified mechanics cultivate safety cultures that prioritise adherence to standards and open reporting systems.
Information Management & Technical Resources
The final domain—information management and technical resources—addresses the use of maintenance manuals, avionics documentation, electrical schematics, and parts catalogs. A&P mechanics must be able to read diagrams, decode wire labels, and trace circuits for troubleshooting.
Knowledge extends to referencing reliable sources for technical data, performing maintenance research, and staying updated through manufacturer bulletins. Familiarity with regulatory websites for AD search, renewal notifications, and FAA advisories ensures currency.
