NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The certificated private pilot was landing to the south on a 600 feet long gravel airstrip. The pilot stated that he thought the winds were fairly calm as he approached to land, but just before touchdown, the wind increased to an estimated 45 miles per hour from out of the south-southeast. He said that a strong downdraft pushed the airplane to the ground, and the main landing gear struck the airstrip, and the airplane nosed down. The airplane sustained substantial damage to the lower fuselage longerons, both landing gear attach points, and both wing spars. The pilot noted that there were no preaccident mechanical anomalies with the airplane.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The pilot's inadequate compensation for wind conditions. Factors associated with the accident were a crosswind, and a downdraft. Full narrative available
