The aircraft was designed as a high wing
regional airliner and cargo transport that could quickly be fitted for
other requirements such as VIP essentially a replacement for older types
such as the early Fokkers and Convairs. Production of the first
generation aircraft occurred between 1985 and 1996. The new generation
variant the -500 is now the standard production model.
The first flight was made on 16th of August 1984 and after successful
trials went into active service with AIR LITTORAL in March 1986. The
next generation models of the ATR 42 received certification on July 28th
1995 before entering service with AIR DOLOMITI.
Construction materials included light alloys and greater use of
composites for the wing roots. The next generation -500 variant
utilises noise absorbing Carbon/Nomex and Kevlar/Nomex construction
including 7 stiffened forward fuselage frames and active vibration
absorbers. A 40% increase on the overhead baggage space and an all new
air conditioning system.
To Date Models are: ATR42-300, 300C (Cargo model, notably an additional
large door version was added to the family in 2000), 300F (Military
Freighter version), 320, and the next generation -500 which included
improvements noted above and with 6 rather than 4 bladed propellers
featuring electronic control, a composite tail and new undercarriage
wheels and brakes.
