Narrative:
Captain applied power for takeoff. As power reached takeoff setting, after autothrottles were selected, we heard a loud bang and felt the aircraft shudder. We were just beginning the takeoff roll and I estimate our speed at 5-10 KTS. Captain initiated abort. We experienced a minor amount of smoke in the cockpit which quickly dissipated. The aircraft had initially veered left, so we just continued toward a taxiway and cleared the runway. We shut the left engine down as we were taxiing clear. Maintenance later showed us several pieces of metal, some 3-4 inches long, which they found in the engine cowl. There was also a layer of metal pieces in the engine exhaust area. All indications prior to the bang were normal, and the engines had warmed up for at least 5 mins prior to runup for takeoff. Callback conversation with reporter revealed the following information: the reporter stated the airplane was a B757-200 with P&west 4037 engines and the maintenance report indicated a failed high pressure turbine blade.
Original NASA ASRS Text
Title: A B757-200 REJECTED TKOF AT 10 KTS DUE #1 ENG LOUD BANG AND SHUDDER CAUSED BY A HIGH PRESSURE TURBINE BLADE FAILURE.
Narrative: CAPT APPLIED PWR FOR TKOF. AS PWR REACHED TKOF SETTING, AFTER AUTOTHROTTLES WERE SELECTED, WE HEARD A LOUD BANG AND FELT THE ACFT SHUDDER. WE WERE JUST BEGINNING THE TKOF ROLL AND I ESTIMATE OUR SPD AT 5-10 KTS. CAPT INITIATED ABORT. WE EXPERIENCED A MINOR AMOUNT OF SMOKE IN THE COCKPIT WHICH QUICKLY DISSIPATED. THE ACFT HAD INITIALLY VEERED L, SO WE JUST CONTINUED TOWARD A TXWY AND CLRED THE RWY. WE SHUT THE L ENG DOWN AS WE WERE TAXIING CLR. MAINT LATER SHOWED US SEVERAL PIECES OF METAL, SOME 3-4 INCHES LONG, WHICH THEY FOUND IN THE ENG COWL. THERE WAS ALSO A LAYER OF METAL PIECES IN THE ENG EXHAUST AREA. ALL INDICATIONS PRIOR TO THE BANG WERE NORMAL, AND THE ENGS HAD WARMED UP FOR AT LEAST 5 MINS PRIOR TO RUNUP FOR TKOF. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE AIRPLANE WAS A B757-200 WITH P&W 4037 ENGS AND THE MAINT RPT INDICATED A FAILED HIGH PRESSURE TURBINE BLADE.
