NTSB Narrative Summary Released at Completion of Accident

On March 1, 2003, a Cessna Conquest, registered in Australia as VH-LBZ, veered off of runway at Lake Johnsonton in Western Australia during a rejected takeoff and was substantially damaged after right engine, a Honeywell TPE331, had an uncommanded increase in power. Airplane was accelerating through 65 knots with engine torque indications matched at 1,200 ft-lbs. Co-pilot, who had been scanning for kangaroos (reported to be a common hazard in this area of Australia), noticed a split in engine exhaust gas temperature indications, left engine 430-440, right engine 500-520. Shortly after this, the power from the right engine increased without any input from the pilot. The pilot rejected the takeoff and retarded both throttles. The left engine decelerated, but the right engine remained at high power. The pilot went through the emergency engine shutdown, but directional control was lost and airplane departed runway. Airplane stopped about 45 meters from left side of runway, 450 meters from start of takeoff roll. There were no injuries to the two pilots and four passengers. The investigation of this incident is under the jurisdiction of the Australian Transport Safety Bureau. This report is for informational purposes only and contains information that was released by or obtained from the Government of Australia.
