Thus, ATR 72 continue to be manufactured and successfully sold throughout the world. The venture became known as ATR. ATR launched the design of a small passenger plane powered by two turboprop engines. The machine became known as the ATR 42 and conducted its maiden flight on 16 August 1984. on 27 October 1988, a 4.5 m (14.7 ft) longer ATR 72 (the figure once again standing for seating capacity) made its maiden flight.
