THE PILOT ABORTED A NIGHT TAKE OFF ROLL AFTER THE RIGHT ENGINE EXPLODED. EXAMINATION OF THE RIGHT ENGINE DISCLOSED THAT THE ENGINE COWLING WAS DISPLACED ABOUT 12 INCHES FROM ITS NORMALLY INSTALLED POSITION. FURTHER EXAMINATION INDICATED THAT THE OUTER BYPASS DUCT AND GAS GENERATOR CASE WERE BURST OPEN FROM THE 12:00 TO 5:00 O'CLOCK POSITION. THE RUPTURE OCCURRED AS THE AIRPLANE ACCELERATED THROUGH 84 KNOTS ON THE TAKEOFF ROLL. THE INVESTIGATION DISCLOSED THAT THE GAS GENERATOR FAILED DUE TO SPOT WELD FATIGUE FAILURE, AND THE EXITING GASES UNDER HIGH PRESSURE BURST THE OUTER BYPASS DUCT, CAUSING EXPLOSION DAMAGE.
