The pilot decided to land on a gravel strip in Cantwell, Alaska, to wait out weather ahead.
During the landing roll, the tailwheel-equipped Piper PA-18 became airborne after passing over a low spot on the gravel. The pilot increased engine power to full to perform a go-around, but the right wing hit a 10-foot-tall post, which he had not seen, and the airplane hit the ground.
The airplane sustained substantial damage to the right wing.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
Probable cause: The pilot’s failure to see and avoid a post during a go-around following a landing on unsuitable terrain.
