Flight Activities
The student pilot began the flight by performing three crosswind landings. Following these, the pilot proceeded to the northeast to practice airwork maneuvers. The pilot then returned to the traffic pattern and prepared for a soft field landing.
Landing and Runway Excursion
The flare and touchdown phases of the landing were uneventful. However, after the aircraft touched down, it drifted to the left. The pilot's control inputs were insufficient to correct the drift, and the airplane departed the runway surface. The aircraft entered an area of soft mud adjacent to the runway.
Accident Sequence
As the aircraft bogged down in the soft mud, the nose wheel collapsed, causing the airplane to nose over. The aircraft came to rest in an inverted position.
Postaccident Findings
A postaccident inspection of the airplane was conducted. No mechanical malfunctions or failures were found. The airplane was operating normally prior to the accident.
