FACTUAL INFORMATION
Shortly after departing Sydney, the flight crew became aware of the
smell of smoke in the flight deck.
Approximately one minute later, the forward cargo fire warning message was
displayed on the engine indicating and crew alerting system (EICAS) screen.
At this time, the Cabin Service Director called the flight crew and reported
smoke mist visible in the passenger cabin. The flight crew reported that
they actioned the appropriate check list, activated the fire suppression
system, and transmitted a MAYDAY. The crew subsequently returned the
aircraft to Sydney, conducting an overweight landing on runway 34L.
While on final approach, the fire warning ceased. Cabin crew reported
that there was no longer smoke in the cabin, but the smell was still
evident. After landing, the aircraft was stopped on the runway where the
emergency services were able to confirm that no fire was visible. The
passengers were then disembarked via mobile stairs placed at the front left
door.
An inspection of the forward cargo bay found signs
of heat damage to a section of the sidewall lining adjacent to the main deck
galley chiller boost fan. On removal of the lining,
the fuselage insulation
blanket between body stations BS880 and BS900 was found burnt, with the
fuselage skin, stringers and frame structure also showing signs of being
heat affected.
The boost fan was found to have a hole burned in its housing adjacent to
the electrical connector, with four of the seven electrical wires burned
through. All of the fan impeller blades were also found to have failed.
The investigation is continuing.
