Accident Details
According to the pilot's statement, the airplane landed on a dirt road adjacent to a closed airport. The airport manager had reportedly granted permission for the pilot to land on the road, which ran parallel to the runway. The pilot had previously landed on the same road on multiple occasions.
During taxi to parking, the road began to curve to the right. The pilot reported feeling "a little push of the tail to the left" due to a wind gust. At that moment, the left wing of the airplane struck a sign post, resulting in the wing separating from the aircraft.
The pilot stated that he had been looking at the post prior to the impact, but did not believe the airplane was in a position to hit it.
Examination
The report notes that the road was parallel to the runway, and the pilot had used it for landing before. No further details about the airplane, airport, or conditions were provided.
