C C M M L5LZCL/A.L A LIS wmm Despite the success of its CRJ, Bombardier continues to trumpet the turboprop such as its 70-seat Q400 737-200s and DC-9s efficiently and need a smaller, more cost-effective jet. Orders: 14 Deliveries 0 DHC-6 TWIN OTTER (DE HAVILLAND) THE P&WC 900kW PT6-powered Twin Otter was first flown in 1965 and the last of more than 830 was built in December 1988. Field Aviation of Canada offers an upgrade, which includes fitting four-bladed Hartzell propellers to reduce external and internal sound levels. Cabin modifications include the fitting of fire-retardant composite interior panels and new lightweight seats. Delivered: 842 In service: 615 DASH 7 (DE HAVILLAND) THE HIGH-WINGED, four-engined, 50-seat Dash 7 was designed for short-field performance, and entered service in 1977. Initial production aircraft were Series 100 passenger or -101 cargo variants. These were superseded by the Series 150 and -151, which offered higher operating weight and fuel capacity. Field Aircraft of Canada offers a gross-weight increase and cargo door and increased fuel-capacity retrofits. Delivered: 113 In service: 98 DASH 8/Q SERIES THE DASH 8/Q SERIES encompasses a four-model family of twin turboprops span ning the 37- to 70-seat market sector. Since 1998, Bombardier has referred to the Dash 8 line as the Q Series, to signify availability of the NVS active noise and vibration reduction sys tem. The 36-seat Dash 8-100, powered by twin P&WC PW120 turboprops, had its maiden flight in June 1983 and entered service in October 1984. A higher-powered version with increased performance, the -200, was introduced in 1992. The 50/60-seat Dash 8-300, incorporating fuselage plugs forward and aft of the wing to produce a 3.35m stretch, was first flown in May 1987, and deliveries began in February 1989. The -300 also has a 1.5m greater wingspan, strengthened undercarriage and uprated P&WC/PW123 engines. The stretched 70-seat Dash 8 Q400 was launched in June 1995, and had its maiden flight in January 1998. The new model is powered by P&WC/ PW150A turboprops driving six-bladed composite propellers. Risk- sharing partners in the Q400 programme include Sextant Avionique, which is supplying the integrated avionics suite, and Mitsubishi Heavy Industries, responsible for die aircraft's forward-, mid- and aft-fuselage sections, wing-to-body fairing, and vertical and horizontal stabilisers. After l,300h of flight testing, the aircraft received Canadian certifi cation in June 1999. The Ultra Electronics NVS is standard on die Q400, and is available on other Dash 8s and for retrofit to earlier models. It reduces cabin noise to around 77dB. Manufacturing delays and problems with the avionics software have led to deliveries of the Q400 slipping several months behind schedule. Bombardier is flight testing an upgraded version of the software, in an effort to eliminate the high level of nuisance warnings currently being generated repeats. Production: Final assembly is undertaken at the de Havilland plant in Downsview, Toronto. Some 25 Dash 8s were delivered in 1999, and production is running at around three to four aircraft a month. Ordered: 650 Delivered: 555 BRJ-X BOMBARDIER HAS scaled back studies of a new family of regional jets in die 100- to 130-seat class, known as the BRJ-X. The design, first unveiled at the Farnborough air show in September 1998, features a five- abreast cabin and a low wing with podded engines. The manufacturer, is re-evaluating this aircraft following rapid growth in the 50 to 70-seat sector of the market and the launch of its CRJ Series 900 (see above). The aircraft also faces tough competition from Airbus and Boeing, offering the A318 and 717 respective ly. Bombardier had been targeting a launch decision for the 100-115-seat BRJ-X-110 by the end of 2000. B-N Group, Bembridge Airport, Isle of Wight P035 5PR.

The purchase by the diversified new owner is expected to enable B-N's product range to be expanded beyond the Islander, Trislander and Defender lines into other markets, including trainers. Part-built aircraft are being completed if customers agree. Six are in various states of construction at B-N's Bembridge base, includ ing three for China Northern Airlines, with a further three part-built by joint venture part ner Romaero in Romania. BN-2B ISLANDER THE ISLANDER FIRST FLEW in June 1965, and entered service in August 1967. The production piston-engined model is available with either two 195kW Textron Lycoming O-540s or two 225kW IO-540s. B-N now supports 860 in-service aircraft and 385 operators. In July 1998 the model's ownership trans ferred from Switzerland's Oerlikon Buhrle to Litchfield Continental. BN-2T TURBINE ISLANDER AN ISLANDER FLEW for the first time in August 1980 with Rolls-Royce (then Allison) 2 50-B 17 turboprops. The BN-2T has tip tanks, and cruise speed and range are sub stantially increased. The latest version is the BN2T-4S, a surveillance and patrol aircraft Model BN2B-26 Islander Length (m) 10.97 Wingspan (m) 14.93 Height (m) 3.78 Wing area (m2) 30.2 Cabin width (m) 1.28 Max takeoff weight (kg) 2.994 Max landing weight (kg) 2,994 Operating empty weight (kg)l,866 Max zero fuel weight (kg) 2.857 Max payload (kg) 930 Powerplant 2 x 194kW TL 0-540E4C5 pistons Standard fuel capacity (1) 492 Normal operating speed (kt) 140 Max cruise speed (kt or Mach)142 Max operating altitude (ft) 13.600 Take-off field length (m) (Sea level /ISA) 370 Landing field length (m) (Sea level/ISA) 300 Accommodation (typical) 10 BN2T Islander 10,86 14.93 • 4.18 30.2 1.1 3,175 3,084 1,832 2,994 1,161 2 x 238kW R-R 250B17C 814 152 170 25,000 380 340 9 Design range, 180km/9 pax l,100km/max fuel /typical loadl 54 FLIGHT INTERNATIONAL 24 - 30 October 200*0
