Incident Overview
A pilot diverted to an alternate airport as dusk approached. The location and information about the airport were obtained from a GPS database. After conducting an approach to land, the airplane struck a pile of dirt while approximately 3 feet above the ground. It then touched down and veered into a wheat field.
Postflight Inspection
A postflight inspection revealed that the airplane had not landed on the airport's turf runway. Instead, it had landed on a parallel runway under construction, described as an 'elevated fill' runway. Information regarding the runway and construction activity was available in the Airport/Facility Directory.
