Boeing 737-400

The Boeing 737-400 is a twin-engined short-to-medium-range narrowbody airliner with a capacity of maximum 188 passengers produced by the American manufacturer Boeing Commercial Airplanes.The Boeing 737-400 is together with the 737-300 and the 737-500 member of the Classic-737-Family.

History

The 737-400 design was launched in 1985 to fill the gap between the 737-300 and the 757-200, and competed with the Airbus A320 and McDonnell Douglas MD-80. It stretched the 737-300 another 10 ft (3.45 m) to carry up to 188 passengers. It included a tail bumper to prevent tailscrapes during take-off (an early issue with the 757), and a strengthened wing spar. The prototype rolled out on January 26, 1988, and flew for the first time on 19 February 1988. The aircraft entered service on September 15, 1988, with launch customer Piedmont Airlines (25 aircraft ordered). The 737-400F was not a model delivered by Boeing, but a 737-400 converted to freighter. The Boeing 737-400 never included winglets as an option, just like the Boeing 737-600. Alaska Airlines was the first to convert one of their 400s from regular service to an aircraft with the ability to handle ten pallets. The airline has also converted five more into fixed combi aircraft for half passenger and freight. These 737-400 Combi aircraft are now in service.

Specifications of the model

Of the 737-300/-400/-500 family, the 400 has proven the most successful member behind the 300, its larger capacity and transcontinental US range meaning it has found a very useful market for Boeing as a 727 replacement. However, the 737-400 does face stiff competition from the similar size Airbus A320, which has higher levels of technology, longer range and is faster (but is also heavier).
