A high school diploma or its equivalent is necessary for all prospective aircraft mechanics. Courses in mathematics, physics, chemistry, electronics, computer science, and mechanical drawing are helpful because many of their principles are involved in the operation of an aircraft and knowledge of the principles often is necessary to make repairs. As new and more complex aircraft are designed, mechanics must update their skills. A working knowledge of composite materials such as graphite is also important, as such materials are increasingly being used in the construction of new aircraft. Aircraft mechanics must do careful and thorough work which requires high mechanical aptitude.
Agility is important for the reaching and climbing necessary for the job.
Aircraft mechanics must not be afraid of heights since they may work on the top of wings and fuselages on large jet planes. As aircraft mechanics gain experience, they have the opportunity for advancement. Opportunities are best for those who have an aircraft inspector's authorization. In the airlines, where promotion is often determined by examination, supervisors may advance to executive positions. With additional career and management training, some open their own aircraft maintenance facilities.
