Boeing is considering a wider and more radical "Next Generation" revamp of its entire 767 programme as it makes what appears to be a last push to launch the 777-100X, with proposals about to be lodged with Northwest Airlines.

Boeing is already studying a longer range 767-400ERX derivative, but hints at more widespread changes to the -300ER and -200ER versions if the shorter 777 option does not go ahead. Plans include the use of the newly developed 767-400ER flightdeck in all three versions, the same interior and possible revival of range extension studies already undertaken for the -300ERX/ERY and possibly enlarged to include the -200.

The move could also include engine and wing improvements on a similar scale to those adopted for the Next Generation 737 family.

"There does not seem to be that much interest in the -100X," says Boeing Commercial Airplanes president Alan Mulally, who adds that enthusiasm has waned even among operators and leasing companies that earlier showed the most interest, such as Singapore Airlines and International Lease Finance. Marginal operating cost benefits remain the biggest hurdle for the -100X, says Mulally, who adds that the 777-based solution is "just too big" for some carriers looking for Airbus A300/A310 replacements.

The case for Northwest, which is looking to replace up to 42 McDonnell Douglas DC-10s, however, appears to be more compelling, says the company.

A rejuvenated 767 family, alternatively, offers "unbeatable" cost performance, says Mulally who adds that airlines are asking for more flexibility to serve a wider range of point-to-point destinations. Boeing is conscious of stiff competition from the A330 family and appears anxious to present customers with new options to the longer range -200, which has damaged the 767 orderbook, and the proposed A330-100X, expected to be launched at next month's Farnborough air show.

Boeing is to choose between developing either the 777-100X or the 767-400ERX and its potential follow-ons by the end of the year. It plans to begin flight tests of the chosen aircraft in late 2003.
