Analysis

The pilot elected to land at a private airstrip due to thunderstorm activity in the denver area. The 2500 foot dirt and sand runway had recently been coated with oil. Rain made the surface slick. The pilot said he touched down and 'had trouble with braking because of water on runway.' Near the end of the runway, the left main landing gear struck a drainage ditch and collapsed. The airplane skidded 100 feet and came to rest on the left edge of the runway. The pilot received two inflight weather briefs indicating thunderstorm activity at the intended destination until mid afternoon. Denver weather was 600 overcast with 6 miles visibility in light rain.
