NTSB narrative
The pilot reported that, during approach, he made a relatively steep descent with full flaps. During touchdown on the unimproved airstrip, the tailwheel-equipped airplane landed hard and bounced. The airplane touched down again angled to the left and veered off the runway to the left during the roll on the uneven, dirt surface. Subsequently, the left wing impacted a tree, and the airplane pivoted into an adjacent tree.
The airplane sustained substantial damage to the left wing and fuselage.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause
The pilot’s improper landing flare, which resulted in a hard, bounced landing and subsequent loss of directional control on an unimproved airstrip.

- 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. 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.
