Boeing said Friday that it would delay deliveries of its 787 Dreamliner until the middle of the first quarter of 2011 because engines won't be ready.
In a statement, Boeing said it won't have the engines ready for final test flights in the fall.
The company said it is working with Rolls-Royce "to expedite engine availability."
Boeing last month indicated that it would be a stretch to deliver the Dreamliner by the end of the year. The aerospace company said that it has had "supplier workmanship issues" and 787 deliveries may stretch into 2011. Now the engine delays have pushed the 787 out farther into 2011.
The Dreamliner is a composite aircraft that has stretched Boeing's supply chain.
