In a conference call with reporters, Boeing Chairman and Chief Executive Officer Jim McNerney said it was "nothing new" to have to rework some of the assembled planes, The Seattle Times reported Thursday.
"There is a significant amount of rework, particularly on the earlier airplanes. But we think we have the scope well defined. The press reports you're seeing describe things that we have planned on," McNerney said.
McNerney said production at the company would increase 40 percent through 2014, "fueling really an unprecedented growth for commercial airplanes."
The production schedule for the Dreamliner calls for construction of 2.5 planes per month by the end of the year and as many as 10 per month sometime in 2013, McNerney said.
