Air accident investigators looking at the latest Boeing 787 Dreamliner fire may have identified the cause.
They have asked that all Boeing 787's switch off an electrical component until further notice.
Last week a fire on the parked Ethiopian Airlines plane closed Heathrow airport for 90 minutes.
In a statement, the Air Accidents Investigation Branch said a transmitter used to locate aircraft after a crash needed more "airworthiness actions".
The body also recommends that regulators conduct a safety review of similar components in other aircraft.
At the start of the year, all 50 Dreamliners in service worldwide were grounded after two separate incidents concerning batteries.
But the AAIB investigators found the fire damage to Ethiopian's aircraft was not near the batteries.
Instead, they have found that the fire was in the upper rear part of the 787 Dreamliner, where the Emergency Locator Transmitter, made by Honeywell, is fitted.
The AAIB statement said: "Detailed examination of the ELT has show some indications of disruption to the battery cells. It is not clear however whether the combustion in the area of the ELT was initiated by a release of energy within the batteries or by an external mechanism such as an electrical short."
As the ceiling space where the ELT is located "do not typically carry the means of fire detection... had this event occurred in flight it could pose a significant safety concern and raise challenges for the cabin crew in tackling the resulting fire."
