Narrative:
I was the captain and PIC of that flight. I was assisted in the cockpit by first officer xyw wwv. We flew ship number xyz, a jetstream 3100. I was the PF. After we started the engines, I called for the after-start check. In response to the after-start check calling for the start locks to be disengaged, I moved the power lever into advance. At that time I observed an increase in the torque of both engines. We completed the after-start checklist. During takeoff roll the right torque remained at 20%. The aircraft pulled to the right. We aborted the takeoff. Subsequently, we disengaged the start lock on the right engine and returned to runway 19L for a second takeoff. Thereafter, takeoff, flight, and landing were conducted within normal operating parameters.
Original NASA ASRS Text
Title: A BAE3100 REJECTED TKOF DUE TO LOSS OF PWR ON #2 ENG CAUSED BY FAILURE TO DISENGAGE THE START LOCK ON #2 ENG. SECOND ATTEMPT OK.
Narrative: I WAS THE CAPT AND PIC OF THAT FLT. I WAS ASSISTED IN THE COCKPIT BY FO XYW WWV. WE FLEW SHIP NUMBER XYZ, A JETSTREAM 3100. I WAS THE PF. AFTER WE STARTED THE ENGS, I CALLED FOR THE AFTER-START CHK. IN RESPONSE TO THE AFTER-START CHK CALLING FOR THE START LOCKS TO BE DISENGAGED, I MOVED THE PWR LEVER INTO ADVANCE. AT THAT TIME I OBSERVED AN INCREASE IN THE TORQUE OF BOTH ENGS. WE COMPLETED THE AFTER-START CHKLIST. DURING TKOF ROLL THE R TORQUE REMAINED AT 20%. THE ACFT PULLED TO THE R. WE ABORTED THE TKOF. SUBSEQUENTLY, WE DISENGAGED THE START LOCK ON THE R ENG AND RETURNED TO RWY 19L FOR A SECOND TKOF. THEREAFTER, TKOF, FLT, AND LNDG WERE CONDUCTED WITHIN NORMAL OPERATING PARAMETERS.
