What happened
The pilot executed an NDB approach before sighting the runway and transitioning to a downwind leg for a visual approach. Under conditions of ground fog that reduced visibility to one and a half miles, the aircraft touched down near the midpoint of the runway in calm wind conditions. The runway surface had been recently resurfaced and was wet with condensation, creating slick conditions. Unable to stop within the remaining distance, the aircraft overran the paved surface and struck a Runway End Identifier Light (REIL). This impact caused the left main landing gear to collapse.
The investigation
Investigation of the event focused on the environmental conditions at the time of touchdown. The runway was confirmed to be wet due to condensation following recent resurfacing work. The pilot reported considering a go-around during the landing roll but decided against it due to trees located at the end of the runway.
Findings
The primary factors contributing to the accident were the wet and slick runway surface caused by condensation on the newly resurfaced pavement, and the limited visibility due to ground fog. These conditions prevented the aircraft from stopping before reaching the runway end.
