Following talks with Japan’s transport minister Akihiro Ota on Thursday, Boeing’s Conner said the company’s proposal to the FAA was a permanent solution, not an interim fix.
“We see nothing in the technology that tells us that it is not the appropriate thing to do. The solution set we put in place provides three layers of protection,” he said in response to a reporter’s question on whether Boeing would consider dropping the lithium-ion battery from the lightweight, fuel-efficient Dreamliner.
“We feel this solution takes into account any possible incident that may occur, any casual factor that could cause an event, and we are very confident we have a fix that will be permanent and allow us to continue with the technology.”
Earlier, Boeing spokesman Marc Birtel said investigations had not shown that overcharging was a factor, and he noted the 787 had quadruple-redundant protection against overcharging. He did not respond directly to comments about GS Yuasa, but said Boeing was coordinating with key suppliers.
No comment was immediately available from Securaplane Technologies Inc, a U.S. unit of Britain’s Meggitt Plc, which makes the charger for the 787 batteries.
All Nippon Airways and Japan Airlines operate nearly half of the Dreamliners that Boeing has delivered to date.
