Physics in Aviation: The Science Behind Aircraft Maintenance Physics is not just something pilots learn in ground school. It shows up everywhere in aviation maintenance: flight controls, hydraulics, fuel systems, propellers, aircraft structures, sheet metal repairs, torque values, weight and balance, and troubleshooting. For an A&P mechanic, understanding physics helps connect what is happening in the airplane to why a component is designed, inspected, adjusted, or repaired a certain way. ...

AC 43.13-1B: Things Every A&P Student Should Know If you are studying to become an A&P mechanic, you are going to hear about AC 43.13-1B a lot. It is one of those references that shows up in school, in FAA test prep, in practical maintenance discussions, and in real hangar conversations. The full title is: Advisory Circular 43.13-1B — Acceptable Methods, Techniques, and Practices: Aircraft Inspection and Repair That title tells you exactly why it matters. It is not just a book of random maintenance tips. It is FAA-published guidance on maintenance methods, inspection practices, and repair techniques that the FAA considers acceptable when they are properly applied. ...

Aircraft Hydraulic Systems: The Basics Every A&P Student Should Know Aircraft hydraulic systems are one of those topics every A&P student needs to understand because hydraulics are used all over the airplane. Depending on the aircraft, hydraulic power may be used for landing gear, brakes, flaps, flight controls, spoilers, nosewheel steering, thrust reversers, cargo doors, and other heavy-duty systems. The basic idea is simple: hydraulics use pressurized fluid to transmit force. ...
