What happened
The incident occurred when a private pilot landed his ski-equipped tailwheel airplane on a frozen seaplane airstrip. After completing the landing, the pilot began to taxi toward the designated parking area. As he initiated a right turn from the landing site, the left main landing gear ski dug into the snow surface. This interaction caused the left main landing gear to collapse. The collapse resulted in structural damage to the fuselage adjacent to the main landing gear attachment cluster.
The investigation
The pilot indicated that there were no preaccident mechanical problems with the airplane. No further mechanical examination details are provided in the source text.
Findings
The primary factor was the left main landing gear ski digging into the snow during a turn on a frozen surface, leading to gear collapse and subsequent structural damage to the fuselage near the attachment cluster.
