Aircraft maintenance specialists are responsible for inspecting, repairing, and servicing various types of aircrafts, such as airplanes, helicopters, and jets. They must adhere to the regulations and standards of the Federal Aviation Administration (FAA) and the manufacturers to ensure that the aircrafts are airworthy and compliant with safety requirements. These specialists check engines, wings, landing gear, instruments, and other components for any defects, damage, or wear. They diagnose and troubleshoot any mechanical, electrical, or hydraulic problems that affect operation. Additionally, they replace or repair any faulty or worn-out parts like tires, brakes, filters, or wires. They also test and calibrate systems and equipment like navigation, communication, or flight control systems. Aircraft maintenance specialists perform routine maintenance and preventive checks on aircrafts such as oil changes, lubrication, or cleaning. Lastly, they keep records and logs of the maintenance work done on the aircrafts like the date, time, and description of the service.
