    The National Transportation Safety Board starts a two-day hearing over the burn-out of the battery system on two Boeing (BA) 787 jets. The NTSB wants to investigate beyond what caused the incidents to the lessons that can be learned for the airplane certification process and new technologies. Boeing chief engineer Mike Sinnett says the only time they could "make a cell vent with fire was with significant overcharging."

    Just when you think the smoke has cleared: Mitsubishi Motors (MMTOY.PK) reports two recent accidents involving lithium-ion batteries manufactured by its joint venture with GS Yuasa (GYUAF.PK), the maker of batteries used in Boeing's (BA -1.1%) grounded 787 Dreamliner. The Japanese auto maker said a lithium-ion battery pack used in its i-MiEV model electric car caught fire while charging during a test inspection at a company plant in Okayama last week, while in another incident, a battery installed in one of its Outlander PHEV hybrids overheated, melting the cell and part of the battery pack.

    Boeing's (BA) 787 could restart flights "in weeks, not in months," the company says after detailing a "permanent fix" for its lithium-ion battery problems that "addresses all (the) causal factors" which led to two burn-outs. Boeing will put the batteries in stainless steel cases, and add extra insulation, spacers and heat-resistant sleeving. Boeing has also asked suppliers Yuasa and Thales to improve production standards.

    Japan's Civil Aviation Bureau and the FAA pay a visit to Kyoto-based GS Yuasa, which provided the lithium-ion batteries that malfunctioned in two Boeing (BA) 787 jets. The investigation is also set to take in a United Tech (UTX) unit that builds the Dreamliner's auxiliary power unit and Meggitt PLC subsidiary Securaplane Technologies, a Tucson company that makes the charger for the batteries.
