The 737-300 in addition to the 737-400 and -500 form the second generation 737 family, with production now over the 3000 mark, a record for a commercial jetliner. This variant initially was intended to be a simple stretch over the 737-200 but Boeing decided to incorporate the CFM International CFM56 high bypass turbofan (jointly developed by General Electric and SNECMA) to reduce fuel consumption and comply with the then proposed ICAO Stage 3 noise limits.
Despite the new engines and the 104in (2.64m) fuselage stretch, the 737-300 retains 80% airframe spares commonality and shares the same ground handling equipment with the 737-200. A number of aerodynamic improvements were incorporated including modified leading edge slats and a new dorsal fin extending from the tail. Another feature was the flattened, oval shaped engine nacelles, while the nosewheel leg was extended to increase ground clearance for the new engines. Other internal changes include materials and systems improvements first developed for the 757 and 767 programs, including an early generation EFIS flightdeck (with four colour CRT screens). |
