Factual narrative
AS THE AIRCRAFT APPROACHED 50 KIAS ON THE TAKEOFF ROLL, IT DRIFTED RIGHT. THE FIRST OFFICER, WHO WAS MAKING THE TAKEOFF, CORRECTED WITH LEFT RUDDER. RIGHT DRIFT BECAME MORE PRONOUNCED AND HARD LEFT RUDDER WAS USED. THE CAPTAIN TOOK OVER, RETARDED ALL THREE THROTTLES, THEN ATTEMPTED TO REGAIN CONTROL BY USING ASYMMETRICAL THRUST. WHEN THIS FAILED, THE THROTTLES WERE RETARDED AND REVERSE THRUST APPLIED. POST INCIDENT INSPECTION DISCLOSED NO APPARENT DAMAGE. THE NEXT MORNING, A DIFFERENT CREW REJECTED THE TAKEOFF WHEN THE NO. 3 ENGINE FAILED. POST INCIDENT DISASSEMBLY AND INSPECTION OF THE ENGINE DISCLOSED METAL IN THE TAILPIPE, SAND AND MUD IN THE COMPRESSOR SECTION, AND A 13TH STAGE AND TWO 14TH STAGE COMPRESSOR BLADES BROKEN OFF, CAUSING EXTENSIVE DAMAGE TO BOTH THE LOW AND HIGH PRESSURE TURBINES.
