Narrative:

After 1/2 hour pleasure flight I returned to airport area. Entered downwind, base, and final for grass runway 25. At touchdown the angle of the sun was such that it became very bright. I don't know if the sun blinded me or if it just broke my concentration. By the time I realized that the aircraft was going to ground loop, my efforts were too late. The aircraft and I ended up in the farm field to the right of the runway. I feel that if I had waited a few minutes until the sun went below the horizon, this situation might have been prevented. I have also included a copy of the NTSB form which I had to fill out.

Title: PLT OF A PLEASURE FLT IN A SPORT BIPLANE HAS GND LOOP ON LNDG DUE TO VISIBILITY REDUCED SUN POSITION.

Narrative: AFTER 1/2 HOUR PLEASURE FLT I RETURNED TO ARPT AREA. ENTERED DOWNWIND, BASE, AND FINAL FOR GRASS RWY 25. AT TOUCHDOWN THE ANGLE OF THE SUN WAS SUCH THAT IT BECAME VERY BRIGHT. I DON'T KNOW IF THE SUN BLINDED ME OR IF IT JUST BROKE MY CONCENTRATION. BY THE TIME I REALIZED THAT THE ACFT WAS GOING TO GND LOOP, MY EFFORTS WERE TOO LATE. THE ACFT AND I ENDED UP IN THE FARM FIELD TO THE RIGHT OF THE RWY. I FEEL THAT IF I HAD WAITED A FEW MINUTES UNTIL THE SUN WENT BELOW THE HORIZON, THIS SITUATION MIGHT HAVE BEEN PREVENTED. I HAVE ALSO INCLUDED A COPY OF THE NTSB FORM WHICH I HAD TO FILL OUT.
