The NTSB's narrative final · quoted from the NTSB record
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.
