Factual narrative

On July 16, 1995, at 2200 Alaska daylight time, a wheel equipped Piper PA-12 airplane, N2941M, registered to and operated by the pilot, ground looped after an aborted landing at Merrill Field, Anchorage, Alaska. The personal flight, operating under 14 CFR Part 91, departed Merrill Field for a local flight. No flight plan was filed and visual meteorological conditions prevailed. The private certificated pilot, the sole occupant, was not injured and the airplane was substantially damaged.

According to the pilot, he was landing the airplane in a light crosswind and the touchdown was firm. The airplane started to ground loop and he attempted to abort the landing by initiating a go around.
