The maintenance and repair of helicopters is the responsibility of a helicopter mechanic. Many countries employ full-time helicopter mechanics in their armed forces divisions, while corporations employ others in this field. Some helicopter mechanics are self-employed, in which case they typically provide services to private individuals and businesses without in-house mechanics.
In many countries, a helicopter mechanic is required to complete some form of formal training in aviation maintenance and repair. Some colleges offer degree programs and other post-secondary education opportunities, and mechanics in the military often receive on-the-job training after completing basic training. Mechanics in some countries must pass licensing or certification exams after completing their training before they can begin working without the direct supervision of an experienced mechanic.
Major corporations frequently hire helicopter mechanics to work on oil rigs and other remote locations only accessible by air. These mechanics, as well as military personnel who specialize in this field, are usually in charge of inspecting and cleaning planes in between flights. A helicopter mechanic must replace transmission fluid, change the air filter, and clean the engine, among other things. In many cases, the helicopter will not be able to fly again until a mechanic has completed a safety inspection and determined that it is safe to fly.
A helicopter, like any other vehicle, can be damaged over time, and parts may need to be replaced. Mechanics are in charge of repairing or replacing rotor blades, tails, and engine components, among other things. When electrical repairs are necessary, the mechanic may need to collaborate with a licensed electrician. Mechanics must also order replacement parts and purchase oil, lubricants, transmission fluid, and other items required to keep the helicopter operational.
A military helicopter mechanic may be required to conduct training sessions in which the crew is given basic instructions on how to perform minor maintenance on the craft. In combat situations, military units may require such skills if the helicopter sustains damage that cannot be easily repaired by a trained helicopter mechanic. Senior mechanics are also in charge of training new hires and performing complex repairs. Some countries’ militaries employ advanced craft that are more complex than standard helicopters. People who work on such craft must undergo special training, and in many countries, military secrets laws prohibit these mechanics from discussing the crafts or their work with anyone outside of their workplace.
