Aircraft Accident/Incident Report

Oshkosh, Wisconsin 54901
Sunday, July 24, 2005 12:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The airplane collided with the runway following a loss of control while landing. The accident occurred as the pilot was arriving at EAA AirVenture 2005. The pilot reported he made a low turn onto final approach, possibly encountered a wind gust, and the airplane stalled. The pilot reported the winds as being from 270 degrees at 11 knots, gusting to 20 knots. The winds reported at the airport 7 minutes prior to the accident were from 250 degrees at 11 knots, gusting to 15 knots.

NTSB Probable Cause Narrative

The pilot's failure to maintain airspeed sufficient enough to compensate for the gusty crosswind condition and prevent a stall during the landing flare. A factor associated with the accident was the gusting crosswind condition.
