What happened
The pilot attempted to land at a private airstrip located at approximately 1,000 feet MSL. The runway was oriented east to west, measuring 2,700 feet in total length. The first 2,000 feet of the runway consisted of grass, while the remaining portion was composed of concrete.
Upon landing on the concrete section, the pilot was unable to bring the aircraft to a stop. The airplane traveled off the end of the airstrip, passed through a fence, and eventually came to rest near the pilot's house. At a nearby airport approximately 10 miles away, the reported weather conditions were a temperature of 84F with winds from 130 degrees at 11 knots, gusting to 14 knots.
The investigation
The investigation included a review of the aircraft's make and model information manual, which indicated a minimum short field landing ground roll of 720 feet. It was determined that the concrete portion of the runway was contaminated with buckshot. Additionally, the investigation found that calculations for the required ground roll did not account for density altitude or tailwind components.
