According to the pilot, the airplane encountered a strong gust of wind that pushed the airplane to the left of the landing strip. Upon leaving the landing strip the nose gear collapsed resulting in substantial damage to the airplane. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported the wind based on a wind sock at the airstrip around the time of the accident to be from 270 degrees at 10 knots with gusts at 20 knots.
