Battery problems resurfaced on Boeing’s 787 on Tuesday, after gas was discovered coming out of a battery on a plane parked in Tokyo.
Boeing said the problem on a Japan Airlines 787 was discovered during scheduled maintenance. No passengers were on board. The company said it appears that a single battery cell ‘‘vented,’’ or released gas.
The incident comes a year after a fire in a lithium ion battery aboard a Japan Airlines 787 parked at Boston’s Logan International Airport. That was followed nine days later by another battery incident that forced an emergency landing in Japan by an All Nippon Airways 787.
Those problems prompted the FAA and other authorities to ground all 787s for more than three months.
