The Federal Aviation Administration's inspection order, which will formally go out within days, is part of the investigation into the cause of a fire board a Dreamliner at a London airport last week. The beacons transmit the aircraft's location in event of a crash.
The New York Times reported investigators are looking at the possibility a pinched wire on a harness connecting a battery to the transmitter ignited or contributed to the fire. The transmitters' batteries on all 787s flying in the United States also will be inspected for possible deterioration, the newspaper said.
The Times said Boeing intends to tell the airlines to either inspect or remove the transmitters.
British investigators had urged the FAA to order airlines to disable the batteries, the newspaper said.
