What happened
The pilot executed a stall landing, touching down on the main gear of the aircraft before lowering the tailwheel to the runway surface after traveling approximately 50 to 100 feet.
Once the tailwheel made contact with the runway, the pilot reported a sensation similar to having slight left brake applied, causing the aircraft to drift toward the left. Although the pilot applied right rudder, the aircraft continued its leftward drift. In an attempt to correct the aircraft's position and return to the center of the runway, the airplane groundlooped to the right. This maneuver resulted in a collapsed left main landing gear.
The investigation
A post-accident inspection was conducted on the aircraft's systems. The investigation revealed no malfunctions or anomalies within the brake system or the directional control systems.
