The ATR 42 is a twin-turboprop, short-haul regional airliner built in France and Italy by ATR. The name "42" comes from the aircraft's standard seating, which varies from 40 to 50. The aircraft was the basis for the ATR 72.
Design and development
The ATR 42 was announced in 1981, making its maiden flight on 16 August 1984; French and Italian certification followed in September 1985 and its first revenue flight was in December of the same year with Air Littoral of France.
As of January 2009 at least 401 ATR 42s have been delivered worldwide with up to 18 aircraft on order.
There are five major variants of the ATR 42.
The -320 was an improved version of the -300 powered by PW121 engines (2100 shp).
The -400 is the official name for the passenger version of the ATR 42 "Surveyor". the -400 is an upgraded version of the -200/300/320 using six-bladed propellers on otherwise identical PW120/PW121 engines. The primary users of this aircraft type are Conviasa & CSA Czech Airlines.
The ATR-500 is the current production version. It is identical in appearance to earlier 42s with the exception of its six-bladed propellers turned by PW127E engines rated at 2,400 shp (1,800 kW) for improved hot and high performance and greatly increased cruise speed. It also has an increased maximum takeoff weight, allowing for more cargo and greater range (up to 1,500 nm).
The new ATR 42-600 and ATR 72-600 will feature the latest technological enhancements while building upon the well-known advantages of the current aircraft, namely its high efficiency, proven dispatch reliability, low fuel burn and operating cost. It will include the new PW127M as standard engine, Glass Cockpit flight deck featuring five wide LCD screens that will replace the current EFIS (Electronic Flight instrument System). In addition, a multi-purpose computer (MPC) will further enhance Flight Safety and operational capabilities. The new avionics, to be supplied by Thales, will also provide CAT III and RNP capabilities. The -600 series ATR aircraft will be progressively introduced during the second half of 2010.
The ATR 42 "Surveyor" is a maritime patrol version of the -500, and VIP transport and in-flight inspection versions of the -500 also exist.
Some 70 other airlines operate smaller numbers of the type.
