SMA HAS ROUGH RUNNING ENG; SPUTTERS; QUITS. LANDS ON BEACH.

Narrative

I WAS FLYING ENRTE FROM AURORA; OR; TO N BEND; OR; IN AN SMA. OVER THE UMPQUA RIVER AREA ON V-287 I EXPERIENCED AN ENG SPUTTER. I THEN REACHED DOWN AND SWITCHED TANKS. AFTER SWITCHING TANKS THE ENG QUIT. THE CLOSEST PLACE FOR A SAFE LNDG; BRINGING NO HAZARD TO PERSONS OR PROPERTY WAS THE BEACH N 2 MI FROM THE N JETTY OF WINCHESTER BAY; OR. I NOTIFIED ONLY N BEND UNICOM ON 122.7 OF MY INTENTIONS AND DECLARED NO EMER TO THEM OF FLT SVC; BECAUSE A SAFE LNDG WAS POSSIBLE. I MADE A SAFE LNDG ON THE BEACH AND THERE WAS ABSOLUTELY NO DAMAGE DONE TO THE ACFT. THE A AND P MECH DETERMINED THE PROBLEM TO HAVE BEEN WATER IN THE FUEL CAUSING THE ENG FAILURE. THERE WAS ONLY MYSELF; THE PLT; ON BOARD ON A PLEASURE FLT; AND I SUFFERED NO INJURIES AND THE ACFT WAS UNDAMAGED. THE FAA DISTRICT OFFICE IN HILLSBORO; OR; WERE NOTIFIED BY COAST GUARD AND THE MESSAGE WAS CONVEYED TO MYSELF THAT I COULD HAVE THE ACFT REPAIRED ON SITE AND FLY IT OFF THE BEACH. I DID SO THE FOLLOWING MORNING. THE ACFT WAS INSPECTED AND NO DAMAGE WAS FOUND.
