Narrative:

Push back, engine start and taxi were uneventful following normal SOP. As the first officer advanced power for takeoff we heard a loud bang and the aircraft yawed right. First officer immediately controled yaw and brought throttles to idle. As we were only at taxi speed I told first officer to continue taxi towards the high speed exit ahead while I informed the tower of the abort and assessed situation. The only cockpit indications were decreasing RPM on #2 engine. I took control of the aircraft and as we taxied clear of runway the tower reported smoke and another aircraft reported fire. I stopped the aircraft and initiated engine fire and evacuate/evacuation procedures which were successful. Initial examination showed an uncontained compressor failure of #2 engine. Callback conversation with reporter revealed the following information: the reporter had just turned onto the active runway and started to advance the throttles when the engine failed. The engine was not at a high power setting. The engine failure was uncontained. Blades exited the compressor case, fan duct and out the top of the cowling. Hot parts set fire to the grass in the area. The engine was a JT8D-7. The reporter was not contacted by the FAA.

Original NASA ASRS Text

Title: A B737-200 EXPERIENCED A CATASTROPHIC UNCONTAINED FAILURE ON TKOF ROLL. ENG WAS A JT8D-7.

Narrative: PUSH BACK, ENG START AND TAXI WERE UNEVENTFUL FOLLOWING NORMAL SOP. AS THE FO ADVANCED PWR FOR TKOF WE HEARD A LOUD BANG AND THE ACFT YAWED R. FO IMMEDIATELY CTLED YAW AND BROUGHT THROTTLES TO IDLE. AS WE WERE ONLY AT TAXI SPD I TOLD FO TO CONTINUE TAXI TOWARDS THE HIGH SPD EXIT AHEAD WHILE I INFORMED THE TWR OF THE ABORT AND ASSESSED SIT. THE ONLY COCKPIT INDICATIONS WERE DECREASING RPM ON #2 ENG. I TOOK CTL OF THE ACFT AND AS WE TAXIED CLR OF RWY THE TWR RPTED SMOKE AND ANOTHER ACFT RPTED FIRE. I STOPPED THE ACFT AND INITIATED ENG FIRE AND EVAC PROCS WHICH WERE SUCCESSFUL. INITIAL EXAMINATION SHOWED AN UNCONTAINED COMPRESSOR FAILURE OF #2 ENG. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR HAD JUST TURNED ONTO THE ACTIVE RWY AND STARTED TO ADVANCE THE THROTTLES WHEN THE ENG FAILED. THE ENG WAS NOT AT A HIGH PWR SETTING. THE ENG FAILURE WAS UNCONTAINED. BLADES EXITED THE COMPRESSOR CASE, FAN DUCT AND OUT THE TOP OF THE COWLING. HOT PARTS SET FIRE TO THE GRASS IN THE AREA. THE ENG WAS A JT8D-7. THE RPTR WAS NOT CONTACTED BY THE FAA.
