The pilot was making an approach to land at his private strip. Wind conditions were gusty and the aircraft was observed to be making a lower approach than was usual. In the vicinity of the boundary fence a substantial increase in engine noise was noted, and the aircraft was seen to be climbing steeply. After reaching a height of about 100 feet the aircraft rolled, descended steeply and struck the ground in an inverted attitude. The reason for the pilot making a lower than normal approach profile was not established. It was determined that the right wing of the aircraft had become entangled with the boundary fence. In an attempt to regain control the pilot had probably instinctively applied large corrective inputs. The fence wire then broke but the aircraft was in an airspeed and attitude configuration such that the pilot was unable to prevent a stall and consequent total loss of control.
