Aviation safety and battery experts say it is likely
that fires on two Boeing 787 Dreamliner planes were caused by overcharging
lithium ion batteries.
An All Nippon Airways Dreamliner was forced to make
an emergency landing in Japan Wednesday after its pilots smelled something
burning in the cockpit.
An investigator said Friday that the battery's
burned insides indicate it operated at a voltage above its design limit.
A similar problem was found on a battery in a Japan
Airlines Boeing 787 parked in Boston's Logan International Airport, earlier
this month.
The Federal Aviation Administration issued an emergency
order Wednesday grounding all the Boeing 787 planes operated by U.S. carriers.
Japan, India, Europe and Qatar also grounded their Dreamliners until the
problem is solved.
U.S. aviation experts arrived in Japan Friday to
help determine what caused a battery to overheat and leak on the All Nippon
Airways Dreamliner jet Wednesday.
