Aviation major, Boeing Co has reportedly asked the operators to investigate emergency beacons on several planes other than its 787 jetliner.

The move comes after Holdings Inc. and United Airlines said that they detected faults linked to the component that caused fire in a parked Dreamliner. The company has asked the operators of 717 as well as next-generation 737, 747-400, 767 and 777 airplanes to inspect aircraft with fixed emergency locator transmitters from Honeywell International.

Marketing Chief Randy Tinseth asked the companies operating the mentioned aircraft operators to aircraft with fixed emergency locator transmitters. The company took the decision after the U. K. Air Accidents Investigation Branch said that the airplanes with fixed Honeywell beacons must be inspected, according to Mr. Tinseth.

Investigators are trying to determine if the two wires a cover on the ELT caused a short-circuit that caused a fire on the Ethiopian Airlines Enterprise 787 at London's Heathrow airport, according to the people closer to the matter.

Megumi Tezuka, an airline spokeswoman for ANA, which is the biggest operator of 787s, said that the company found a dented wire in a fixed beacon and another in a portable beacon during the previous week. The airline has since removed all beacons from the eight 787s that were used in the domestic service.

"Boeing is asking specific operators of 717, Next-Generation 737, 747-400, 767 and 777s to inspect aircraft with the Honeywell fixed emergency locator transmitters. The purpose of these inspections is to gather data to support potential rule-making by regulators," a Boeing spokesman said in an emailed statement late on Sunday.
