First Incident
During the takeoff roll, as the aircraft approached 50 knots indicated airspeed, it began to drift to the right. The first officer, who was handling the takeoff, applied left rudder to correct. The right drift became more pronounced, prompting the use of full left rudder. The captain then took control, retarded all three throttles, and attempted to regain directional control using asymmetrical thrust. When that proved unsuccessful, the throttles were retarded and reverse thrust was applied. A post-incident inspection revealed no apparent damage to the aircraft.
Second Incident
The following morning, a different crew was operating the same aircraft. During the takeoff roll, the crew rejected the takeoff when the No. 3 engine failed. Subsequent disassembly and inspection of the engine disclosed metal in the tailpipe, sand and mud in the compressor section, and that the 13th stage and two 14th stage compressor blades had broken off. This caused extensive damage to both the low pressure and high pressure turbines.
