## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE PILOT GROUND LOOPED AFTER RACING. THERE WAS A THERMAL (DEVIL DUSTER) OVER THE FIRST THIRD OF THE LANDING RUNWAY WHICH MAY HAVE CAUSED THE AIRCRAFT TO FLOAT. UPON TOUCHDOWN, THE AIR CIRCULATION CHANGED DIRECTION CAUSING A SUDDEN SIDE LOAD, WHICH THE PILOT DID NOT REACT TO QUICKLY ENOUGH. THE AIRCRAFT GROUND LOOPED AND INCURRED DAMAGE TO TWO CONTROL SURFACES. THERE WAS NO DAMAGE TO THE REST OF THE AIRFRAME, ENGINE AND PROPELLER.
