SEATTLE: The Boeing Co. has pushed back the date for a possible replacement for its popular 737 jet by several years, saying it needs more time to advance the underlying technology.
Chicago-based Boeing put together a team to �study the possibility of creating a new airplane for the narrow-body market� in 2006, Boeing spokeswoman Sandy Angers said. Since the 737's 1967 debut, the aircraft has won Boeing more than 6,000 orders.
Angers said conversations with airline customers made it clear that requirements for a replacement plane—15% to 20% better fuel efficiency, 25% lower maintenance costs—would require major technological advances in aerodynamics, materials, and the jet's engine and electrical systems, among other areas.
In response, Boeing has now reduced its 737-replacement airplane design effort and will focus on technology research and development.
Angers said first deliveries of a replacement 737 are now expected in the latter part of the next decade, instead of in 2012 as first predicted.
