Alenia Aeronautica's manufacturing facilities in Pomigliano d'Arco, near Naples, Italy, produce the aircraft fuselage and tail sections. Aircraft wings are assembled at Sogerma in Bordeaux in western France by Airbus France. Final assembly, flight-testing, certification and deliveries are the responsibility of ATR in Toulouse, France.
ATR 82 - During the mid-1980s, the company investigated a 78 seat derivative of the ATR 72. This would have been powered by two Allison AE2100 turboprops (turbofans were also studied for a time) and would have a cruising speed as high as 330 knots (610 km/h; 380 mph). The ATR-82 project (as it was dubbed) was suspended when AI(R) was formed in early 1996.
ATR stretch - In 2007, as a response to the Q400X proposal, ATR floated the idea of a 90-99 seater stretch. As of 2009, it was considered as part of the future -900 series ATR family. In 2011, the 90-seater proposal was brought to its shareholders as a proposal. As of 2012, a new clean sheet design has been considered in the 90-seat segment, for a 2017 launch.
