Narrative:

When we attempted a takeoff from runway 21 at chs, the first officer was flying. V1 was 101 KTS. Upon reaching approximately 95 KTS, the #2 engine started to bypass fuel, resulting in a loss of between 10-15 percent torque. This caused a noticeable yaw to the right. The first officer called 'malfunction.' I called 'reject' and took command of the airplane. We instructed chs tower we wished to taxi back to conduct a run-up. During the run-up, all engine parameters were normal and the previous condition could not be reproduced. We proceeded with another takeoff and completed it successfully.

Title: LTT ABORTS TKOF WHEN AN ENG LOSES PWR.

Narrative: WHEN WE ATTEMPTED A TKOF FROM RWY 21 AT CHS, THE FO WAS FLYING. V1 WAS 101 KTS. UPON REACHING APPROX 95 KTS, THE #2 ENG STARTED TO BYPASS FUEL, RESULTING IN A LOSS OF BTWN 10-15 PERCENT TORQUE. THIS CAUSED A NOTICEABLE YAW TO THE R. THE FO CALLED 'MALFUNCTION.' I CALLED 'REJECT' AND TOOK COMMAND OF THE AIRPLANE. WE INSTRUCTED CHS TWR WE WISHED TO TAXI BACK TO CONDUCT A RUN-UP. DURING THE RUN-UP, ALL ENG PARAMETERS WERE NORMAL AND THE PREVIOUS CONDITION COULD NOT BE REPRODUCED. WE PROCEEDED WITH ANOTHER TKOF AND COMPLETED IT SUCCESSFULLY.
