Narrative

THE FLT BLOCKED OUT OF THE GATE AT XA28. THE APU WAS PLACARDED INOP. THE #1 ENG WAS STARTED AT THE GATE AND WE PUSHED BACK. UPON TAXI; THE #2 ENG WAS STARTED VIA THE XBLEED START CHKLIST. ALL NORMAL AFTER START AND TAXI CHKLISTS WERE ACCOMPLISHED. THE CAPT WAS THE PF. WHEN WE BRIEFED THE TKOF; V1 WAS CALCULATED TO BE 137 KIAS. WE WERE GIVEN TKOF CLRNC ON RWY 19. TKOF THRUST WAS APPLIED AT APPROX XA40; AT 80 KTS; I CALLED '80 KTS THROTTLE HOLD; ENG INSTS CHK;' ENG INDICATIONS WERE NORMAL; AS WAS THE ACCELERATION OF THE PLANE. DURING TKOF ROLL; A LOUD BANG WAS HEARD AND THE ACFT VEERED TO THE R. THE CAPT REJECTED THE TKOF. AT THAT POINT OF THE REJECTED TKOF; THE ACFT'S NOSE CONTINUED DOWN THE CTRLINE OF THE RWY AND SLOWED NORMALLY. WE EXITED THE RWY TO THE R AND I POINTED OUT THAT THE #2 ENG EGT WAS INDICATING APPROX 600 DEGS C; AT IDLE THRUST. ALL OTHER INDICATIONS APPEARED NORMAL AT THAT TIME. THE CAPT INSTRUCTED ME TO SHUT DOWN THE #2 ENG. A NORMAL SHUTDOWN PROC WAS ACCOMPLISHED. WE RECEIVED A RADIO CALL FROM TWR INDICATING THAT THEY HAD SEEN A SMALL PUFF OF SMOKE FROM ONE OF THE ENGS ON TKOF ROLL; JUST PRIOR TO OUR REJECTED TKOF. WE CALLED OPS AND REQUESTED A TUG AND ASSISTANCE WITH GETTING A VISUAL INSPECTION OF THE ACFT. TWR THEN INFORMED US THAT SOME DEBRIS WHICH APPEARED TO BE ENG PARTS; WERE FOUND ON THE RWY. THE LCL OPS PERSONNEL INSPECTED THE AIRPLANE AND DETERMINED THAT THE TAIL PIPE OF THE #2 ENG HAD SOME DEBRIS IN IT; BUT THERE WERE NO OTHER PROBS INDICATED WITH THE REST OF THE ACFT. AFTER ALL CHKLIST ITEMS WERE ACCOMPLISHED; WE EXITED THE ACFT TO VISUALLY INSPECT THE ACFT. LCL OPS PERSONNEL HAD FRAGMENTS OF WHAT APPEARED TO BE TURBINE BLADES; WHICH THE ARPT AUTH HAD BROUGHT TO THEM. A VISUAL CHK OF THE #2 ENG REVEALED NO VISIBLE DAMAGE TO THE FIRST VISIBLE STAGE OF COMPRESSOR BLADES; INTAKE OR EXTERNAL HOUSING/COWLING. LOOKING UP THE TAIL OF THE ENG REVEALED CONSIDERABLE DAMAGE TO THE VISIBLE TURBINE BLADES; AND THAT SOME DEBRIS LAY IN THE TAIL PIPE AREA. NO OTHER DAMAGE WAS VISIBLE. ALL DAMAGE WAS CONTAINED IN THE ENG COMPARTMENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE AIRPLANE WAS A B737-200 WITH PRATT & WHITNEY JT8D-15A ENGS. THE RPTR SAID THE CAUSE OF THE ENG FAILURE HAS NOT BEEN RPTED BY MAINT BUT WAS AN ENG CHANGE.
