An investigation has been concluded into the cause of a small fire that forced an Etihad Airways plane to divert during a flight from Abu Dhabi to Sydney, Australia.

During the flight last October, a burning smell was detected in the flight deck and the forward cargo compartment fire warning was activated.

The flight crew armed and set the forward cargo fire suppression system and diverted the aircraft to Adelaide for a safe landing.

A report by the Australian Transport Safety Bureau (ATSB) found that a wiring loom situated above the forward cargo compartment was incorrectly routed, likely during the manufacture of the Boeing 777-300 aircraft.

Over several years, wires in that loom had chafed against the support structure and short circuited. Electrical arcing created smoke that activated the forward cargo smoke detector, it said.

The report said the Etihad flight crew declared a Mayday to air traffic control and advised of their intention to divert to Adelaide Airport.

The aircraft landed safely and all passengers and crew disembarked with zero injuries reported.

The ATSB said Boeing had proactively sent out warnings to all 777 operators in response to the incident and had received reports of five other similar incidents.

Boeing also issued a service bulletin which required operators to inspect for and correct similar conditions that led to this occurrence.
