The ATR 72 is a twin-engine turboprop short-haul regional airliner manufactured by the French-Italian aircraft manufacturer ATR. It was developed as a stretched variant of the ATR 42, and entered service in 1989. It has been typically employed as a regional airliner, although other roles have been performed by the type such as corporate transport, cargo aircraft and maritime patrol aircraft. Successive models of the ATR 72 have been introduced, a single aircraft can seat up to 78 passengers in a single-class configuration.
