An aircraft mechanic is a skilled professional responsible for maintaining and repairing airplanes and helicopters. They ensure that all aircraft are safe and ready for flight by performing routine inspections, troubleshooting issues, and replacing faulty parts. Their work is crucial for the safety of passengers and crew. To become an aircraft mechanic, individuals typically need a high school diploma and specialized training, often through an aviation maintenance technician school. Many mechanics also obtain certification from the Federal Aviation Administration (FAA) in the United States, which requires passing written, oral, and practical exams to demonstrate their knowledge and skills.
