During an aerial observation flight with a gusting wind and an adequate supply of fuel on-board, the pilot reported that the engine suddenly lost power after encountering a downdraft. Attempts to restore engine power were unsuccessful and the pilot maneuvered the airplane for a forced landing on wet grass near a monument. After touchdown, with excess speed to account for the gusting wind, the airplane bounced several times. During the landing roll, and with no braking action due to the wet grass, the pilot was unable to stop the airplane, which then collided with a culvert and nosed over. Postaccident examination of the engine revealed no evidence of preimpact mechanical failure or malfunction. While the mixture control at the carburetor was in the idle cut-off position, impact damage to the engine mount likely pulled the control to that position. While a detailed inspection of the magnetos revealed that the primary contact point gap was considerably less than specified, the investigation was unable to determine that this caused the loss of engine power.
Probable Cause: A loss of engine power for undetermined reasons following a reported severe turbulence encounter.
