Two fuselage plugs, one on each side of the wing, increase overall length by 4.72m compared to the baseline 50-seater. Other changes from the basic CRJ include more-powerful GE CF34-8C1 engines, in redesigned nacelles. The main landing gear, wheels and brakes have been upgraded for the higher operating weights. The CRJ700 first flew in 1999 and European launch customer Brit Air received the first aircraft in January 2001. In March, the CRJ700 was the subject of an emergency FAA airworthiness directive (AD) after an incident in which an incorrect fuel transfer allowed the centre tank to overfill during flight, caus ing fuel venting. The long-term fix involves replacing fuel-pump couplings in all CRJ700s. Meanwhile, the FAA limited flight to within 60min of a diversion airport and mandated additional fuel loads as a safety precaution. Separately, Bombardier is working on post-production modifica tions to update avionics, improve crew cautions and remove nuisance messages, to solve a number of problems that have hindered the aircraft's introduc tion into service. Bombardier is marketing a longer-range ER ver sion of the CRJ700. This incorporates the wing of the larger CRJ900, which is structurally reinforced, as well as the CRJ900's main landing gear wheels, which have been strengthened for higher landing speeds, and its Liebherr environmental control sys tem, redesigned around a ram-air flow modulation valve for faster cabin temperature pull-down time. By making the CRJ900 wing standard on the CRJ700, production will be simplified, and will enable the jet to operate at the higher weight and extend by around 370km. Production Initial production of the CRJ700 was undertaken at Bombardier's Dorval plant in Montreal, but assem bly was transferred to a new plant at Montreal's international airport, Mirabel, in 2001. Twenty-two CRJ700s were delivered in 2001 and production is running at at a rate of around three a month. Ordered: 198 Delivered: 50 CRJ900 The CRJ900, a minimum-change stretch derivative of the CRJ700, was launched at the 1999 Farnborough air show. The 86-seater's fuselage was extended by inserting two fuselage plugs of 2.25m and 1.55m. It also features a strengthened wing, two more overwing exits and uprated GE CF34-8C5 'engines. The first prototype, modified from the CRJ700 development aircraft, flew in February 2001 and achieved Transport Canada certification in September this year. Deliveries to launch customer Mesa Air Group are due in the first quarter of 2003. The aircraft is certificated at the CRJ900ER's higher MTOW of 37,400kg, although the baseline model will operate at 36,500kg. Follow-on testing will include an increase in MTOW to 38,300kg for the CRJ900LR within 12 months, giving it a maxi mum range of 3,590km. Bombardier has received almost 80 letters of intent about the aircraft, but only 30 firm orders so far. Mesa has ordered 20 aircraft, with 20 more on option. Production The CRJ900 is built alongside the CRJ700 at Bombardier's Mirabel plant in Montreal. Twelve examples are to be delivered to Mesa in 2003. Orders: 30 Deliveries 0 DHC-6 Twin Otter (de Havilland) First flown in 1965, the last P&WC PT6-powered Twin Otter was built in 1988. Field Aviation of Canada offers an upgrade of the aircraft, including fitting four-bladed Hartzell propellers to reduce external and internal sound levels, and fitting light weight seats. Delivered: 842 In service: 599 I •<T Bombardier is studying a longer-range CRJ700ER which would incorporate elements of the CRJ900 www.flightinternational.com FLIGHT INTERNATIONAL 12-18 NOVEMBER 2002 51
