What happened
During the landing roll, the aircraft became airborne as it traveled over a crown or crest in the runway. To prevent a stall, the pilot applied full power and attempted to continue with a go-around. However, the aircraft settled back onto the runway.
The pilot determined there was insufficient airspeed and remaining runway length to complete the go-around. Despite applying heavy braking, the aircraft was unable to stop within the runway limits. The aircraft continued off the departure end of the runway and descended down an embankment toward a highway. To avoid hitting the road, the pilot intentionally swerved the aircraft to the right. During this turn, the left wing struck uneven terrain, resulting in damage.
Findings
Investigation of the site revealed that the first part of the runway featured a 3% upslope grade. At the time of the event, the pilot estimated the wind was from 020 degrees at 15 knots, gusting to 25 knots.
