NTSB narrative
Prior to takeoff, the pilot had conducted left and right clearing circles, and was aware that the right brake was "spongy." He decided to continue with the flight and took off on a local area flight that lasted for an hour. Upon returning to the airport, he noted that there was a southerly crosswind about 10-13 knots. The pilot performed a normal wheel-landing and the airplane began to weathervane to the left of the runway on the rollout. The pilot activated the right rudder and brake pedal to correct back to centerline, but the airplane continued to the left of the runway. As the airplane continued off the runway's edge into snow, the left main tire caught in the snow, pivoted the airplane, and the airplane came to rest on its nose. The airplane's braking system was inspected by an FAA inspector who noted that the right brake was "spongy," and that with very little applied force to the pedal it would "bottom out."
Probable cause
The pilot's continued operation with a known mechanical problem and failure to maintain directional control.

Source notes (4)
- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
