NTSB narrative
THE PILOT WAS LANDING ON A RUNWAY WHERE THE SURROUNDING TERRAIN IS LOWER AT THE APPROACH END OF THE RUNWAY. ON SHORT FINAL TO THE RUNWAY, THE PILOT LOST SIGHT OF THE LANDING AREA. THE LEFT MAIN LANDING GEAR STRUCK THE RISING TERRAIN AT THE APPROACH END OF THE RUNWAY, COLLAPSED, AND THE AIRPLANE GROUND LOOPED. THE PILOT HAD JUST PURCHASED THE HOMEBUILT BI-PLANE 2 DAYS PRIOR TO THE ACCIDENT. THE PILOT'S TOTAL FLYING EXPERIENCE IN BI-PLANES WAS THE 7 HOURS FLOWN IN THIS AIRPLANE. THREE OF THE FLIGHT HOURS WAS ACCOMPLISHED DURING A FERRY FLIGHT FROM OHIO TO NEW YORK. THE PILOT DID NOT RECEIVE ANY DUAL INSTRUCTION IN THE AIRPLANE, ONLY A VERBAL BRIEFING. THE PILOT WAS NOT AWARE OF THE LOSS OF FORWARD VISIBILITY, AND THE HIGH DRAG AND CORRESPONDING HIGH SINK RATES DURING SLOW, POWER OFF APPROACHES.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN A PROPER GLIDEPATH. A FACTOR IN THIS ACCIDENT WAS THE PILOT'S LACK OF TOTAL EXPERIENCE IN THIS TYPE OF AIRPLANE.

Source notes (4)
- 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.
