Japan says unable to give time frame for Boeing 787 jet restarts
TOKYO (REUTERS, AP) – Japan’s Civil Aviation Bureau said on Friday it is not yet at the stage where it can estimate when commercial flights for Boeing Co’s Dreamliner jet would resume after the plane was grounded globally for battery problems.
Boeing said earlier in the day that it expected the certification process for its proposed battery fix on the 787 jet to be completed in weeks.
Boeing executives said Friday they had not pinpointed the causes of the two battery problems that resulted in the global grounding of the technologically advanced Dreamliner planes.
But Boeing chief project engineer Michael Sinnett said a new design has many layers of safeguards to prevent battery fires and overheating.
