Description

On 27 June 2016, the augmented flight crew of a Boeing 777-300ER (9V-SWB) being operated by Singapore Airlines on a flight from Singapore to Milan observed an indication of low oil quantity in the right engine after having reached their initial cruise altitude. After further abnormalities in respect of the performance of the right engine occurred, it was decided to set the right engine thrust to flight idle and return to Singapore at FL170. A subsequent landing on runway 20C after fuel dumping was followed by signs of substantial right engine distress and the outbreak of fire in and around the right engine and adjacent wing structure. The initially substantial fire was brought under control within about 5 minutes and did not affect the fuselage so it was determined that an emergency evacuation was not necessary and passengers were subsequently disembarked from the aircraft via steps. The fire effectively destroyed the right engine and parts of the right wing and ignited pooled fuel which also damaged the runway surface.
