Aircraft Mechanic Under Pressure T-Shirt

The ICAO defines the licensed role of aircraft maintenance (technician/engineer/mechanic), noting that "The terms in brackets are given as acceptable additions to the title of the license. Each Contracting State is expected to use in its own regulations the one it prefers."[9] Thus, aircraft maintenance technicians, engineers and mechanics all perform essentially the same role. However different countries use these terms in different ways to define their individual levels of qualification and responsibilities.
