At approximately 0104 Eastern Standard Time on 25 Aug 2004, the left engine surged during takeoff from Runway 34 at Melbourne Airport. The crew of the Singaporean registered Boeing 777-312 aircraft, 9V-SYB, subsequently reported that the surge occurred just at V1. The crew elected to continue the takeoff and the left engine surged multiple times during the departure, until they shutdown the engine. Due to forecast turbulence, the crew maintained an altitude of approximately 3,000 ft above ground level to dump fuel and reduce the aircraft’s weight for landing. Air Traffic Services vectored the aircraft over Port Phillip Bay for the fuel dump, which took approximately 1 hour, before the aircraft was returned to Melbourne for an uneventful single-engine landing. There were 300 persons on board and there were no reported injuries.
An examination of the engine found that several of the High Pressure Compressor (HPC) casing liners had eroded to the point of reducing the efficiency of the HPC.
