Aircraft mechanics are responsible for maintaining aircraft and keeping them airworthy. They are like doctors for planes. There are different license categories for aircraft technicians depending on their skills and the parts of maintenance they work on. To be a certifying staff who can release an aircraft after maintenance, individuals must pass examinations to prove their knowledge, gain experience working on maintenance in an approved organization, and be authorized by a maintenance organization according to regulations. The requirements and experience needed vary depending on a person's education but the goal is to ensure the safety of all flyers. Gold Air Training Center in Istanbul, Turkey provides aircraft maintenance training programs and type courses to help individuals obtain their licenses and authorizations.
