A related factor was the crosswind condition. ## Sequence of events In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf). - Loss of control - on ground/water, landing - roll - weather condition - crosswind (contributing factor) - directional control - not maintained, pilot in command (cause) ## Analysis The student pilot stated that the aircraft landed a 'little hot' and bounced. The aircraft veered to the left (west) side of the runway and the pilot elected to initiate a go-around. Before the aircraft became airborne, it collided with a pile of excavated rock and dirt located on the west edge of the runway. The aircraft came to rest approximately 20 feet from the runway edge. The pilot reported that at the time of the accident the wind was from 090 degrees at three to five knots, gusting to ten knots. Hillsboro Airport, located eight miles north of Twin Oaks, was reporting the wind from 110 degrees at 14 knots at the time of the accident. ## Factual narrative On February 20, 1999, about 1430 Pacific standard time, a Cessna 150L, N16058, registered to Twin Oaks Airpark, Incorporated, and operated by the student pilot as a 14 CFR 91 instructional flight, was substantially damaged during the landing rollout at the Starks Twin Oaks Airport, Hillsboro, Oregon.
