| Aerospatiale and Aeritalia (now Alenia) established Avions de Transport Regional as a Groupement d'Intéret Economique under French law to develop a family of regional airliners. The ATR-42 was the consortium's first aircraft and was launched in October 1981.The initial ATR-42-300 was the standard production version of the ATR-42 family until 1996 and features greater payload range and a higher takeoff weight than the prototypes. The similar ATR-42-320 (also withdrawn in 1996) differed in having the more powerful PW-121 engines for better hot and high performance, while the ATR-42 Cargo is a quick change freight/passenger version of the 42-300. The ATR-42-500 is the first significantly improved version of the aircraft and features a revised interior, more powerful PW-127Es for a substantially increased cruising speed (565km/h/305kt) driving six blade propellers, a 1850km (1000nm) maximum range, the EFIS cockpit, elevators and rudders of the stretched ATR-72 (described separately), plus new brakes and landing gear and strengthened wing and fuselage for higher weights. The first ATR-42-500 delivery was in October 1995. |
