Narrative:
A Cessna 208B airplane, N879MA, sustained substantial damage after overrunning the end of runway 2 during the landing roll at the Kapalua Airport (JHM), Hawaii. The airplane was being operated as Flight 504 by Mokulele Airlines, as a scheduled commuter flight.
According to the captain, during the second flight of the day, while landing at Kapalua, the first officer was the pilot flying, and he was the monitoring pilot. He added that, during the approach to the 3,000 ft. long, by 100 ft. wide asphalt-covered runway, the airspeed was about 35 knots too fast, and the airplane touched down about halfway down the runway, "a little longer than normal". He said that after touchdown, the first officer moved the propeller thrust lever into beta range (reverse), but "something didn't feel right" and that the airplane was not decelerating. Subsequently, the captain took control of the airplane, applied the thrust lever to full reverse, but the airplane did not slow down. The captain said that he applied maximum brakes, but the main landing gear wheels locked and began to skip. The airplane subsequently overran the departure end of runway 2 and continued down an embankment, and into an area of tree and brush-covered terrain, sustaining substantial damage to the left aileron.
The first officer reported that, during the approach, the airplane was a little fast and floated longer down the runway than normal. He was not sure of the exact touchdown point but noted that he did not hear any loud noise typically associated with the application of the beta. The captain then took the flight controls and applied full reverse with no change or deceleration. The captain then applied full brakes, but the airplane exited the runway. All crew and passengers evacuated through the main door and nobody was injured.
Probable Cause: The pilots failure to maintain a proper approach speed and their decision to continue the approach for landing, which resulted in the airplane landing long and a subsequent runway overrun.
