BOEING has delivered its 7,500th new aircraft - a B737-400 to Garuda Indonesia. It was the 121st and last B737 to be delivered by Boeing in 1993. Its 7,499th new aircraft, another B737 jetliner, was delivered to Xinhua Airlines in Beijing, the last plane introduced by China's civil airlines in 1993. That brings the total number of civil aircraft of all types received by China's booming airlines over the year to 71. Garuda's new twin-jet, outfitted for 124 passengers in a two-class configuration, was put into service on domestic and regional service immediately. Of the 71 aircraft delivered to China in 1993, China Aviation Suppliers Co (CASC) said 68 were large and medium-sized passenger aircraft. Forty-seven were Boeings, four Airbus Industrie, four McDonnell Douglas, six Fokker, four BAe146 regional aircraft from British Aerospace and three Ilyushin-86s from Russia. China Southern Airlines topped the domestic aviation companies by introducing 17 new aircraft. Air China, Southwestern Airlines and Eastern Airlines each introduced eight. Two Ilyushin-86 passenger craft were wet-leased by Northern Airlines and two Tupolev-154s by Zhejiang Airlines to serve China's domestic air routes. In addition, statistics show that in 1993 the CASC signed contracts with foreign aircraft companies on the buying and leasing of 104 aircraft, which will be delivered gradually between 1994 and 1998.
