ATR 42

The ATR 42 is a twin-turboprop, short-haul regional airliner developed and manufactured in France and Italy by ATR (Aerei da Trasporto Regionale or Avions de transport régional), a joint venture formed by French aerospace company Aérospatiale (now Airbus) and Italian aviation conglomerate Aeritalia (now Leonardo S.p.A.).

The number "42" in its name is derived from the aircraft's standard seating configuration in a passenger-carrying configuration, which typically varies between 40 and 52 passengers.

Besides used as commercial aircraft, the ATR 42 has also been used as a corporate transport, cargo aircraft and maritime patrol aircraft as well.

To date, all of the ATR series have been manufactured at the company's final assembly line in Toulouse, France; ATR benefits from its sharing of resources and technology with Airbus SE, which has continued to hold a 50 percent stake in the company.

Improved models of the aircraft have been introduced, incorporating new avionics such as a glass cockpit, and the adoption of newer engine versions for enhanced performance, such as increased efficiency and reliability along with reductions in operational costs.

The aircraft serves as the basis for the larger ATR 72, which was also developed during the late 1980s to complement its smaller sibling. The ATR 42 and ATR 72 have been produced side-by-side for decades.
