NTSB investigators may have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot noted the wind sock indicated the wind was about 20 degrees left of runway centerline. After making a normal crosswind landing, the airplane nosed to the right and he made a correction. When the airplane assumed a three point attitude, it veered to the left. He corrected with right rudder "without letting the wind under left wing" but it had no effect and the airplane departed the runway and nosed over. The pilot said the bolt securing the tail wheel leaf spring had sheared and the tail wheel was driven up against the rudder. A search of the area failed to locate the nut or the bolt end. He said the break was an "extrusion and clean downward shear," but an FAA inspector who examined the airplane stated the damage was consistent with that of a hard landing. Official recorded winds were 320 degrees at 7 knots, with gusts to 14 knots.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: the pilot inadvertently flaring the airplane too high above the ground, resulting in a hard landing that sheared a bolt in the tail wheel assembly. This rendered directional control impossible and induced an uncontrolled ground loop. A contributing factor was the crosswind. Full narrative available
