New York - US aviation authorities sat they are working "to develop instructions to operators" on how to inspect the emergency beacons suspected of causing a fire on a Boeing Dreamliner in London recently.
"After reviewing the initial findings" from Britain's Air Accidents Investigation Branch, "the Federal Aviation Administration is working with Boeing to develop instructions to operators for inspection of the Emergency Locator Transmitters on Boeing 787 aircraft," the FAA said in a statement.
These inspections will be mandatory and operators will need to check for evidence of "proper wire routing and any signs of wire damage or pinching" in the Honeywell-made beacons, the FAA said.
Airline companies with 787s in their fleet will also be required to "inspect the battery compartment for unusual signs of heating or moisture," the statement added.
The FAA said it would publish its directives in the coming days.
Britain's Air Accidents Investigation Branch recommended on Thursday that distress beacons onboard all Boeing Dreamliners be disabledafter a fire broke out on an empty Ethiopian Airlines plane parked at Heathrow airport.
