## Analysis

The pilot reported that he was landing the airplane at a private landing strip on his property. The flag near the landing location indicated a calm wind. The pilot said that the airplane encountered some turbulence and wind gusts during the landing approach. He attempted a go-around and made a right turn to avoid the rising terrain. He said that he did not maintain flying speed and the airplane impacted trees and the wing spars were substantially damaged. The pilot said that there were no mechanical malfunctions with the airplane.
