THE AIRPLANE BEGAN TO DIVERGE TO THE RIGHT OF THE RUNWAY CENTERLINE DURING THE INITIAL TAKEOFF RUN AT A GROUND SPEED OF BETWEEN 20 AND 30 KNOTS. THE PILOT-IN-COMMAND (PIC) GLANCED AT THE ENGINE INSTRUMENTS AND OBSERVED AN ASYMMETRY IN TORQUE BETWEEN THE PLANE'S TWO ENGINES. THE PIC REPORTED THAT IN HIS HASTE TO ACCOMPLISH THE ABORT, HE WAS NOT ABLE TO GET THE LEFT POWER LEVER BACK TO THE GROUND IDLE POSITION PRIOR TO THE IMPACT WITH THE NORTHWEST ARRESTING BARRIER PIT. THE PIC SAID THAT HE DEPRESSED THE NOSE WHEEL STEERING BUTTON BUT DID NOT PUSH THE BUTTON ON THE ENGINE POWER LEVER TO ENGAGE THE NOSE WHEEL STEERING. THE REASON FOR THE DELAYED OR DECREASED TORQUE FROM THE NO. 2 ENGINE COULD NOT BE CONCLUSIVELY DETERMINED.
