Incident Overview
A pilot reported that during the landing flare, the airplane encountered a gust of wind. Subsequently, during the landing roll, the airplane departed the runway to the left. As a result of the runway excursion, the right main landing gear separated from the airplane. The airplane then skidded on dirt and rocks parallel to the runway, sustaining substantial damage to the firewall.

A review of recorded data from the automated weather observation station located on the airport revealed that 5 minutes before the accident, wind conditions were 310 degrees true at 3 knots. The airplane was landing on runway 33. Additionally, data from 15 minutes after the accident showed wind conditions of 340 degrees true at 19 knots, gusting to 26 knots.
Mechanical Status
The pilot reported that there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
