Aircraft maintenance engineers ensure safety across assigned aircraft. In order to do this, they perform maintenance, both scheduled and emergency. This can include dismantling, inspecting, testing, repairing and reassembling aircraft engines; installing electrical circuits; testing aircraft communication equipment, aircraft instrumentation, and electronic systems; replacing and testing aircraft oxygen system components; assembling parts and subassemblies of aircraft frames; and conducting routine preflight inspections of engines and mechanical systems. They are also required to keep detailed records of the maintenance performed.
