The ATR 72 is a twin-engine turboprop, short-haul regional airliner developed and produced in France and Italy by aircraft manufacturer ATR. The number "72" in its name is derived from the aircraft's typical standard seating capacity of 72 passengers. The ATR 72 has also been used as a corporate transport, cargo aircraft, and maritime patrol aircraft.

Certified in January 1997 and fitted with either PW127F or PW127M engines, the -212A (marketed as the ATR 72-500) is an upgraded version of the -210 using six-bladed propellers on otherwise identical PW127F engines. Other improvements include higher maximum weights and superior performance, as well as greater automation of power management to ease pilot workload.
