Singapore Airlines Flight 368


Singapore Airlines Flight 368 was a scheduled international passenger flight from Singapore Changi Airport to Milan–Malpensa Airport in Italy. On 27 June 2016, the Boeing 777-300ER operating the flight to Italy turned back to Singapore after an engine oil warning. While landing at Changi Airport, the plane's right engine caught fire. All passengers successfully evacuated the aircraft. There were no injuries among the 241 passengers and crew involved.

Aircraft

The aircraft involved in the incident was a Boeing 777-312ER, registered as 9V-SWB, bearing the manufacturing serial number of 33377, equipped with two General Electric GE90-115B engines. At the time of the incident, the aircraft was nine years old, having been delivered new to Singapore Airlines on 5 November 2006. It underwent major repair works for four months before returning to service on 12 November 2016.

Investigation

The Air Accident Investigation Bureau of Singapore, which is responsible for investigating aviation accidents in Singapore, opened an investigation into the occurrence. Their investigation found that the right engine's oil system was contaminated with fuel due to a crack in the engine’s main fuel oil heat exchanger. The engine's manufacturer General Electric had already identified that certain MFOHEs were cracking and instructed that they be removed from the engines and inspected then repaired if necessary. The Service Bulletin issued by General Electric detailing the inspection and repair recommended that the inspection of the MFOHE be done the next time the engine was sent to a workshop for maintenance. In the case of the engine that failed, the most recent time it had gone to a workshop was March 2014, several months before the bulletin had been issued.
