Flight and Approach
The pilot and a passenger flew locally for about an hour before returning to the accident airport. During a fly-over, the pilot observed that windsocks at both runway ends were hanging straight down. He flew a normal left-hand pattern and verified the airplane was configured for landing on base leg. On final approach, he determined no crosswind correction was necessary.
Landing and Rollout
The landing flare and touchdown were normal. However, during the rollout, the tail veered to the right. The pilot increased power to execute a go-around, but the airplane began turning and the right wing lifted. He reduced power and applied corrective flight control inputs, but the right main landing gear collapsed. The airplane veered off the runway and came to a stop.
Wind Conditions Reported
The pilot reported that wind at the airport was light and variable, gusting to 10 knots. After exiting the airplane, he noted gusting wind conditions from the north, west, and northwest, between 5 and 10 knots. He stated he has experience landing in gusty conditions, but that the crosswind on the day of the accident was variable and unpredictable, with no warning.
