According to the pilot, he checked the weather at his destination airport and it called for VFR weather. While enroute to his destination, he stated that the weather was deteriorating and the ceilings were getting low. As a precaution, he started to look for a place to land since the weather was closing in and his fuel was also getting low. The pilot located a private grass strip and made an attempt to land. As the airplane touched down on the field, the pilot applied the brakes, but he had little brake response due to the wet grass. When the pilot realized that he would be unable to stop the airplane prior to the end of the runway, he initiated a go-around and struck a power line followed by trees before losing control and colliding with the ground. The airplane sustained substantial damage to both wings and the fuselage. The pilot did not report any mechanical anomalies that would have precluded normal operation prior to the accident.
