Aircraft involved

Probable cause & findings

The pilot’s failure to maintain directional control during the landing roll. Contributing to the accident was the pilot’s unstabilized approach.

Factual narrative

The pilot of the tailwheel equipped biplane reported that she extended her downwind due to other aircraft in the traffic pattern, and that while on the extended final she put the biplane in a "slip". During the slip, she reported that the windsock was out of view. She further reported that during the landing flare she noticed her "ground-speed" was higher than normal, and that "about 800 ft." after touchdown, the biplane "violently swerved to the right". She attempted to recover with rudder inputs, however the biplane veered off the runway and came to rest inverted. The biplane sustained substantial damage to the empennage. The pilot reported there were no pre-accident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
