ASA Aviation Maintenance Technician General Practice Test

The main thing being tested is how much practical hands-on maintenance experience you need to qualify for a mechanic certificate with both airframe and powerplant ratings. For the combined A&P rating, the standard requirement is 30 months of practical experience in aircraft maintenance. This time must be earned in an aviation environment, performing maintenance tasks and typically under supervision, so you gain broad, real-world exposure to both airframe and powerplant work. If you complete an FAA-approved aviation maintenance technician school program, you can qualify with fewer months—18 months—through that pathway. The other options listed (fewer months) don’t meet the standard duration for the combined rating, while one extra month beyond the standard path isn’t required unless you’re following that school-based route.
