Narrative:

After landing an aircraft (conventional gear) at a farm strip, aircraft spun around in a ground loop on the rollout. Aircraft had safely touched down and was slowing. Although field was inspected before hand, and pilot was experienced in aircraft, incident was due to soft spot in turf. Once ground loop began, impossible to stop. Conclusion was that older aircraft with narrow conventional landing gear present ground handling problems, even under ideal conditions.

Title: GA PLT LOST CTL OF AN SMA TAIL DRAGGER AFTER LNDG AND MADE A GND LOOP. CLAIMS HE HIT A SOFT SPOT IN THE RWY.

Narrative: AFTER LNDG AN ACFT (CONVENTIONAL GEAR) AT A FARM STRIP, ACFT SPUN AROUND IN A GND LOOP ON THE ROLLOUT. ACFT HAD SAFELY TOUCHED DOWN AND WAS SLOWING. ALTHOUGH FIELD WAS INSPECTED BEFORE HAND, AND PLT WAS EXPERIENCED IN ACFT, INCIDENT WAS DUE TO SOFT SPOT IN TURF. ONCE GND LOOP BEGAN, IMPOSSIBLE TO STOP.
