United Airlines is currently the only US airline operating the 787. Boeing said it supported the FAA but said it was confident the 787 was safe.
Earlier, Japan's two main airlines grounded their 787s after the battery failure prompted an emergency landing. United Airlines is the only US airline operating the 787. Earlier, Japan's two main airlines grounded their 787s.

Japan Airlines then took similar action, saying it would ground its fleet of seven 787s from 16 January until further notice. Japan Airlines then took similar action, grounding its seven Dreamliners.
Boeing shares closed down more than 3% on Wall Street on Wednesday. Along with United's six Dreamliners, it means well over half of all Dreamliners in operation are now grounded.
Broader problems
In recent weeks, Dreamliners have suffered issues including fuel leaks, a cracked cockpit window, brake problems and an electrical fire.In recent weeks, Dreamliners have suffered issues including fuel leaks, a cracked cockpit window, brake problems and an electrical fire.
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. Finding answers
Boeing shares closed down more than 3% on Wall Street on Wednesday.
"Boeing is committed to supporting the FAA and finding answers as quickly as possible," said Boeing chief executive Jim McNerney.
"We are confident the 787 is safe and we stand behind its overall integrity. We will be taking every necessary step in the coming days to assure our customers and the travelling public of the 787's safety and to return the airplanes to service.
"Boeing deeply regrets the impact that recent events have had on the operating schedules of our customers and the inconvenience to them and their passengers."
United Airlines said it would immediately comply with the FAA's directive and would begin re-accommodating customers on alternative aircraft.
Follow suit?
The FAA said 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.
Leithen Francis, from Aviation Week, said that could mean more bad news for Boeing in the coming days.
"When the FAA issues an airworthiness directive civil aviation and airlines around the world have to follow the FAA airworthiness directive, particularly in regards to the 787 because it a US-designed and developed aircraft," he told the BBC.
In the longer term, he said that airlines considering putting in orders for the 787 may now hold off or choose to increase orders of rival Airbus' A330, a comparable plane.
"The Airbus A330 is a proven product," he said.
Under investigation
Late on 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 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.

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.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."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.
