What happened
The pilot initiated a diversion to a planned alternate airport because of fog conditions at the intended destination. This alternate site was situated on a ridge line approximately 2,700 feet higher in elevation than the original target airport. The available runway measured only 2,200 feet in length and lacked any ground services.
According to witness accounts, the pilot landed with excessive speed near the middle of the strip. The aircraft left skid marks measuring between 330 to 350 feet along the pavement. Unable to stop within the available distance, the aircraft departed the end of the runway, descended an embankment, and entered a wooded area.
The pilot reported that there were no mechanical malfunctions with the aircraft prior to the incident.
