He also stressed that the new finding has little to do with the overheating, since the battery system has a diode module to block any reverse current. As the JTSB has found nothing wrong with the module, it is believed to have functioned normally, he said.
and this could cost billions in lost time and man power to correct. Clock is ticking and all we hear and read is the 787 won't get another test flight until April. And remember faulty circuity could be as big as a problem and battery.
Still, the chairman said he is concerned there may be other irregularly installed circuitry.
