A massive increase in airport capacity, with 90 new airports due to open in the next 10 years, will help triple the size of the mainland's market for small jets, according to leading manufacturer Bombardier. Trung Ngo, a vice-president of Asia-Pacific sales for commercial aircraft at Canada's Bombardier Aerospace, said a large proportion of the new facilities would be in the western part of China, where passenger demand and airport constraints in mountainous areas would mean aircraft in the 100 to 150-seat range were more suitable than larger airliners. Overall, Ngo said, there were 500 passenger aircraft with between 100 and 149 seats operating on the mainland, but this would grow to 1,680 aeroplanes by 2030, according to Bombardier forecasts. Ngo added that Bombardier predicted the global market for this size of aircraft would climb from 4,800 planes to 7,320 in the next 20 years. To tap into this sector, Bombardier is developing its C-series aircraft in association with Shenyang Aircraft Corp, which already makes fuselage sections and other components for Bombardier's Q400 turboprop aircraft. Ngo said the final design of the C-series was being completed for the first flight in 2012. He said the first of the two aircraft in the series, the 110-seat CS100, would be delivered starting in 2013, while first deliveries of the 130-seat CS300 would take place a year later. He added that the 'CS100 is designed for hot and high airfields. The C-series is very attractive to Chinese airlines. We believe we will get a significant share of the [100-149-seat] segment.' Ngo said Bombardier was in discussions with mainland and other airlines about potential aircraft orders for the C-series and remained confident 'we will successfully conclude the discussions'. The manufacturer has sold 29 of its smaller 50-70 seat CRJ series of regional jets to operators on the mainland and in Taiwan. But the potential market for the C-series is much larger. Bombardier has so far secured orders for 33 CS100 and 57 CS300 aircraft from two airlines from Europe and the United States and an Irish leasing company, while the three operators have options for 90 more of the same types. Ngo said the C-series would offer a 20 per cent fuel saving and cut operating costs by 15 per cent compared with similar sized aircraft through advanced engines, composite materials and design. He said Bombardier had already worked with the Civil Aviation Administration of China on a computer analysis of operating a C-series aircraft in hot and high conditions between Lhasa and Chengdu. Shenyang Aircraft Corp is currently building a new factory that will make fuselage sections for the C-series that will be shipped to Canada for final assembly and fitting out. This will follow the Shenyang company's involvement on the Q400 programme in which all the fuselage sections of the aircraft are manufactured on the mainland for final assembly in Canada.
