## Analysis

The student pilot reported that during the landing roll on Runway 19 the airplane suddenly went into a "violent left [and] right tipping movement" and exited the right side of the runway. Subsequently, the airplane impacted the segmented circle near the windsock, which resulted in structural damage to the airplane. The pilot reported no flight control anomalies with the airplane prior to the accident. The weather observation station located at the airport reported shortly after the accident wind from 300 degrees at 9 knots.
