Détails:
The Jetstream touched down at a speed of 98.5 knots following an uneventful flight from Washington. The captain reported that he got a red beta light after pulling both throttles to idle, so he did not use reverse. After landing on runway 21, the airplane rolled out to the end, turned left onto the last taxiway A, then continued onto a grass apron, and down a 60-foot embankment with a 47-degree slope.
Examination of the FDR data revealed that about 13 seconds after touchdown, and approximately 70 knots, engine power decreased and the spoilers deployed. Five seconds later, engine power increased and the spoilers stowed. A review of the FDR data from the two landings previous to the accident flight revealed that engine rpm stabilized around 72 percent, and engine torque stabilized around 6 percent, during the landing roll. A review of the accident landing revealed that engine rpm remained between 80 and 100 percent, and engine torque values were between 22 and 30 percent, until the airplane went over the embankment.

Probable Cause:

PROBABLE CAUSE: "The captain's improper application of power after responding to a beta warning light during landing rollout, which resulted in an excessive rollout speed and an inability to stop the airplane before it reached the end of the runway."
