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 pilot entered the downwind leg of the traffic pattern and noted that the windsock was indicating calm winds. He completed the normal rectangular traffic pattern with no indications of the wind conditions changing. During touchdown a gust of wind from the west raised the right wing, allowing the airplane to drift left. The pilot unsuccessfully attempted to correct the drift and then attempted a go-around. The pilot aborted the go-around when he saw a back hoe in his path. The airplane's left wing then collided with the back hoe, which was parked unattended about 20 to 30 feet from the runway's edge. After the accident, the winds were noted to shift periodically with gusts above 15 miles per hour.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

failure of the pilot to adequately compensate for gusting crosswind conditions and to maintain directional control. A factor in the accident was unattended construction equipment parked in close proximity to the runway edge.
