Background
Prior to taxi, the pilot reported having Automatic Terminal Information Service (ATIS) information "Whiskey," which indicated variable winds at 7 knots. The pilot was cleared to taxi to Runway 09 and subsequently cleared for takeoff with instructions to remain in right traffic.
Flight Details
The flight proceeded downwind, base, and final approach. During the final approach with 30 degrees of flaps extended, the pilot later reported that he did not flare sufficiently, causing the airplane to bounce slightly. The airplane then porpoised two times.
Accident Sequence
The pilot subsequently learned that the propeller had contacted the left runway edge. He attempted to take off again before the airplane departed the runway, but the attempt was unsuccessful. The airplane exited the left side of the runway, collided with a taxiway light, and rolled onto the grass between the runway and Taxiway E. The nose landing gear struck a berm, resulting in the collapse of the nose gear and the airplane nosing over.
Post-Accident Information
The pilot stated that he lost consciousness upon impact with the berm and regained consciousness while the airplane was inverted. Both occupants exited the airplane through the passenger door. A METAR issued at 1153 local time indicated wind from 170 degrees at 7 knots. Review of FAA Order 7110.65N, titled "Air Traffic Control," notes that ASOS/AWOS is considered the primary source of wind direction, velocity, and altimeter data for weather observation purposes. The pilot had received a high-performance signoff prior to the accident flight, with the training consisting of 5 hours.
