Gulfstream American Corp AA-5B N51LL accident near Hillsboro, Oregon

Probable cause

The pilot’s delayed remediation following an aborted takeoff run, which resulted in a runway overrun and collision with trees.

NTSB analysis

The pilot reported that, he was on a long cross-country flight and had stopped at several airports along the way. He reported that during a takeoff run, he accelerated to rotation speed and heard the stall warning horn oral alert when he attempted to lift the nosewheel off the ground. The pilot elected to abort the takeoff as the airplane did not appear to be accelerating sufficiently. At the time, the airplane was about halfway down the runway. According to the pilot, as there was between 800-1,200 ft of runway remaining at the time, he retarded the throttle and applied some brake pressure, but the airplane did not decelerate as he had anticipated. The pilot recounted that he took his feet off the rudder pedals multiple times to ensure they were correctly placed. He then applied maximum pressure to the brake pedals, but the airplane overran the runway end, traversed a road, and impacted trees. The wings were substantially damaged.

The pilot stated that the brake system did not perform as he had anticipated. However, postaccident examination of the brake system did not reveal any anomalies. Further, the pilot reported that he did not experience any abnormalities with the brakes when he used them to stop at other airports during other legs of the cross-country flight.
