SEATTLE - Boeing says its second 787 jet needs to have its fuel tanks cleaned out before it can resume flight testing after small amounts of debris were found in the tanks.
The jet took off from Boeing Field on Thursday to fly to Everett for the cleanup.
Boeing spokesman Scott Lefeber described the debris as particulates that were left in the tank during the manufacturing process. He told The Seattle Times the company has refined the manufacturing inspections to make sure it doesn't happen again.
Lefeber says the cleaning process is expected to be completed pretty quickly, though he would not be more specific.
Boeing began flying its first two 787s in December.
The 787 program has been plagued by ill-fitting parts and other problems. The first flight was supposed to be in 2007, but Boeing was forced to push that back five times.
