Having received your A&P license or formal aircraft maintenance training, you will be working on many different aspects of aircraft. Depending on where you work, you could be showing up to work for a major inspection of an aircraft. That consist of taking many parts of the airplane off and inspecting inside and out. Changing tires, brakes, fluids, etc. That also consists of operational checks of systems to verify they function properly. Sometimes aircraft come into the shop broke and you have to trouble shoot and figure out the problem before fixing it with new parts. It can be a very rewarding job to see a plane turn apart and put back together.
