According to the pilot, he was returning to the airport due to an approaching thunderstorm. The pilot entered traffic for runway 15, and while on final, noticed that the wind had shifted to favor runway 33.

Both wings separated, the propeller was bent, and the horizontal stabilizer was crushed and wrinkled. The pilot reported no anomalies with the airframe or airplane systems.
