Summary
A pilot landing an airplane experienced a loss of directional control after a wind gust from the right exceeded the aircraft's crosswind capabilities. The airplane departed the runway, and all landing gear collapsed when it encountered sand adjacent to the runway surface.
Sequence of Events
The pilot received runway information from UNICOM but did not receive wind information. During the approach, the pilot observed the windsock pointing perpendicular to the runway, though it was not fully extended. Upon landing, the airplane encountered a wind gust from the right that exceeded the crosswind capabilities of the airplane. This gust caused a loss of directional control, and the airplane departed the runway.
Damage
After departing the runway, the airplane encountered sand next to the runway, and all three landing gear collapsed as a result.
