TOKYO, March 8 A Japanese transport ministry
official said on Friday that it knew of past incidents involving
circuit boards on Boeing Co Dreamliners operated by All
Nippon Airways Co (ANA), but authorities do not think
they are linked to the jet's battery problems.
ANA, which along with Japan Airlines Co has nearly
half of the 50 Dreamliners delivered to date, said this week
there had been three instances of electric distribution panel
trouble in its 787 jets before it grounded the aircraft in
January. It also said it had to replace the panel twice.
