During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot of the tailwheel-equipped airplane reported that, during a wheel landing, the wind shifted from a crosswind to a quartering tailwind. He further reported that, he had full aft elevator applied, but lost control of the pitch when the wind shifted, and the airplane nosed over about 5 to 10 knots groundspeed.

The airplane sustained substantial damage to the left wing and vertical stabilizer.

The pilot did not report that there were any preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

The pilot did not submit the NTSB Form 6120.1 Pilot/Operator Aircraft Accident/Incident Report.
