Narrative:

On landing rollout; a gust of wind from the west lifted the right wing and caused the aircraft to weather-vane into the wind. The left wingtip contacted the runway surface; but the aircraft was corrected back onto all 3 wheels before departing the runway surface at a 45 degree angle at approximately 40 mph. Braking was applied in an attempt to stop the aircraft in the runway shoulder of gravel which is approximately 30 feet wide while avoiding a runway edge light. Braking was limited to ensure the aircraft did not nose over causing the prop to strike the ground. There was no prop strike; but just prior to coming to a stop the right main gear rolled down a steep embankment on the side of the runway. At that point gravity pulled the right wing down causing it to impact the ground. There were no injuries to either occupant. The aircraft was pulled back onto the runway and rolled to the ramp. From a visual inspection by the pilot the damage is limited to the right wing tip; left wing tip and a crack in the plexiglass over the cockpit.the problem arose when insufficient control inputs were applied to counter the unexpected gust from the right. This airport does not have any type of weather reporting other than the wind sock which did not indicate gusty winds on initial overflight or on final approach. The lack of visual or control feel wind indications lead to a perception of calm conditions resulting in a lack of preparation for the gust on landing rollout.
