## Findings

NTSB's coded findings; those marked are part of the probable cause.

- [Use of equip/info: aircraft control](https://openairdocs.org/ntsb-findings/02063040): Personnel issues › Task performance · Pilot (probable cause)
- [Performance/control parameters: directional control](https://openairdocs.org/ntsb-findings/01062020): Aircraft › Aircraft oper/perf/capability · Not attained/maintained (probable cause)

## Analysis

The pilot of the tailwheel-equipped airplane reported that, he was performing practice landings on a dry lakebed. After the second landing, he felt the right rear of the tail lift and move left. The airplane continued to decelerate, and the pilot attempted corrective control inputs, but the left wing stuck the ground and the airplane nosed over. The airplane sustained substantial damage to the vertical stabilizer and both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
