Updated with new information

Boeing announced today that it will fly two 787s back to Seattle, where they will remain parked while the company continues its investigation into a fire that occurred during a Nov. 9 test flight in Texas. Both planes have landed at Boeing Field in Seattle as of 5:18 p.m. Tuesday.

Boeing 787 spokesperson Lori Gunter said that "no decision has been reached on when flight testing of the 787 will resume. Before that decision can be made, we must complete the investigation and assess whether any design changes are necessary. Until that time, Boeing cannot comment on the potential impact of this incident on the overall program schedule."

The 787 is almost three years behind schedule. Passenger service has been scheduled for the first quarter of 2011, but glitches with parts shortage and new materials has delayed its commercial release six times.

New data shows that the duration of the incident was less than 90 seconds. The fire, which started in a bay under the cabin floor and resulted in the loss of primary electrical power, lasted for less than 30 seconds

The team investigating the Texas incident has finished a series of inspections on the jet and are replacing the power panel and insulation blanket that burned. They are also repairing minor structural damage that occurred during the fire, Gunter said. "Though more work remains to complete the investigation," she said.
