NTSB Factual Report

The pilot of the tandem-seat, tailwheel equipped biplane reported that he was flying from the rear seat which limits his forward view, "especially in the landing configuration". He further reported that during the landing roll on a private grass airstrip, the biplane impacted a drainage pipe, which resulted in a collapsed left landing gear and substantial damage to both lower wings and the lower right aileron.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to avoid the drainage pipe during the landing roll on a private grass airstrip. Contributing to the accident was the pilot's reduced forward view from the rear seat.
