Analysis

The pilot stated that after landing at the appropriate airspeed without the banner on runway 9, she applied appropriate airplane control corrections to maintain the airplane on the runway centerline, but immediately after touchdown a strong gust caused the airplane to ground loop to the right. She said that she applied control corrections to counteract the wind, but the airplane did not respond. The left main landing gear collapsed, and the left wing incurred damage. The pilot said that there were no pre-accident anomalies with the airplane or any of its systems.
