Probable cause

The pilot's failure to maintain the runway heading during an aborted go-around, which resulted in a hard landing.

Findings · 2

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during landing, the biplane touched down right of the centerline, and the propeller struck the runway. He added power to go around, but the biplane drifted right, so he maneuvered it toward a grass field right of the runway and shut off the engine. He then leveled the biplane, and it subsequently landed hard, and the main landing gear collapsed. The biplane sustained substantial damage to the right-wing "I" strut. The pilot reported that there were no preaccident mechanical failures or malfunctions with the biplane that would have precluded normal operation.

Factual narrative
