Late Wednesday, the FAA said it would work with the manufacturer and carriers on an action plan to allow the US 787 fleet to resume operations as quickly and safely as possible.
"The in-flight Japanese battery incident followed an earlier 787 battery incident that occurred on the ground in Boston on January 7, 2013," the regulator said.
"The AD (airworthiness directive) is prompted by this second incident involving a lithium ion battery."
It said the battery failures resulted in the release of flammable electrolytes, heat damage, and smoke, and the cause of the failures was under investigation.
"These conditions, if not corrected, could result in damage to critical systems and structures, and the potential for fire in the electrical compartment," the FAA said.
The regulator added that when it issues an airworthiness directive, it also alerts the international aviation community so that other authorities can take parallel action to cover the fleets operating in their countries.
