Courses in these trade schools generally last from 2 years to 30 months and provide training with the tools and equipment used on the job. For an FAA certificate, attendance at such schools may substitute for work experience. However, these schools do not guarantee jobs or FAA certificates. Aircraft trade schools are placing more emphasis on newer technologies such as turbine engines, aviation electronics, and composite materials including graphite, fiberglass, and boron, all of which are increasingly being used in the construction of new aircraft. Less emphasis is being placed on older technologies such as woodworking and welding.
Employers prefer mechanics who can perform a wide variety of tasks.
Mechanics learn many different skills in their training that can be applied to other jobs. Some aircraft mechanics in the Armed Forces acquire enough general experience to satisfy the work experience requirements for the FAA certificate. With additional study, they may pass the certifying exam. Most mechanics have to complete the entire training program at a trade school, although a few receive some credit for the material they learned in the service. 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.
