(.19) On July 21, 2001, at 1700 central daylight time, a anderson revelation, N6116S, piloted by a commercial pilot, sustained substantial damage during an in-flight collision with the terrain following a loss of control during initial climb from runway 08 (2,280 feet by 175 feet, dry/turf) at the Wautoma Municipal Airport, Wautoma, Wisconsin. Visual meteorological conditions prevailed at the time of the accident. The test flight was conducted under the provisions of 14 CFR part 91 and was not on a flight plan. The pilot, the sole occupant, reported minor injuries. The proposed local flight was departing at the time of the accident. According to the pilot, the airplane was recently certified as an amateur-built aircraft and was departing on its second flight since certification. The pilot reported that during the first flight the engine tachometer was reading 1,000 RPM lower than the specified range. The pilot stated that subsequent to the first flight the propeller blade pitch was adusted to a finer setting to achieve the desired static engine RPM. According to the pilot, on the second flight, the airplane did not accelerate normally when out of ground effect. The pilot s tated that the aircraft entered a stalled condition, resulting in a collision with the terrain. (-23) aircraft stalled after takeoff on test flight. Density alt at the time was 3800'. Pilot began shallow turn to avoid obstacles and wind stalled. Aircraft had less than 15 min on and a new prop was being test flown.
