NTSB narrative
The pilot of the tailwheel-equipped airplane reported that shortly after touchdown, during the landing roll, the tail began to rise, and the airplane subsequently nosed over. Skid marks on the runway were consistent with the right main wheel skidding during landing. The airplane sustained substantial damage to the left wing. A postaccident examination of the airplane revealed that the parking brake cable was binding. This binding prevented full travel of the parking brake to the “OFF” position and not fully release, which resulted in un-commanded braking application during landing roll.
Probable cause
The binding of the parking brake cable, which resulted in un-commanded brake application during the landing roll and subsequent nose over.

- 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, cause areas. 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.
