Incident Overview
A pilot reported that during a landing on runway 18, the airplane experienced unexpected movements and subsequently contacted the terrain with both wings. The local wind was from the west at 10 to 15 miles per hour.
Pilot Account
According to the pilot, on touchdown the airplane 'lurched' to the left. When he applied a correction, it 'lurched' to the right and seemed to become airborne. The pilot then added power in an attempt to abort the landing. However, the right wing contacted the terrain. Subsequently, the left side of the airplane contacted the ground, at which point the left main landing gear brace broke. This resulted in the left wing and left horizontal stabilizer also contacting the terrain.
Additional Details
The landing was conducted on a concrete runway. The pilot noted that he normally operated from a grass airstrip.
