The pilot said he was making a normal approach to runway 3 after he received ASOS weather information from the airport, which stated that the winds were from 070 degrees at 5 knots. He said the approach was normal and the landing was smooth. Immediately after touchdown, a gust of wind caused the airplane to begin to ground loop. The airplane rotated 90 degrees to the left, departed the runway, and struck an electrical box with the right wing. The pilot stated there were no mechanical malfunctions or failures with the airplane.
