What happened
Prior to entering the traffic pattern, the student pilot assessed wind conditions using the midfield tetrahedron and windsock. The observed wind was approximately 340 degrees at 10 miles per hour, which placed it at a right angle to runway 7R.
The pilot entered a standard 45-degree approach from the northeast and subsequently initiated a left 90-degree turn onto the base leg while experiencing a tailwind. While transitioning to the final approach sequence, the pilot monitored the centerline of the glider runway.
During the rollout onto the final approach, wind conditions caused the aircraft to be blown across the southern boundary fence. As the aircraft crossed back over the fence line, the left wing made contact with a fence post.
