Mechanic (Powerplant)
Credential: Mechanic (Powerplant)
Credentialing Agency: Federal Aviation Administration (FAA)
Renewal Period: Lifetime
Mechanic (Power Plant) This is a mid-level certification and requires years of training and experience to perform. Power plant mechanics are authorized to work on engines and do limited work on propellers. Mechanics work in hangars, repair stations, or out on the airfield on the "flight lines" where aircraft park. Mechanics often work under time pressure to maintain flight schedules or, in general aviation, to keep from inconveniencing customers. At the same time, mechanics have a tremendous responsibility to maintain safety standards, and this can cause the job to be stressful.
More information can be found on the certifying agency's website.
