Aircraft Accident/Incident Report
Rio Creek, Wisconsin 54201
Sunday, June 24, 2007 11:45 CDT
NTSB Narrative Summary Released at Completion of Accident
The airplane impacted terrain following a loss of control during initial climb when, according to the pilot, the airplane engine had a total loss of engine power. One witness stated that the airplane stalled while climbing over trees, while another stated that he did not hear the engine stop. The airplane was about 243 pounds over its gross takeoff weight. The pilot stated that he thought he calculated a weight and balance for the flight which he thought were within limits. Examination of the airplane revealed that both propeller blade tips were missing, having fracture surfaces consistent with rotational overload separation. There was also a propeller slash mark that preceded the wreckage, which, in conjunction with the propeller tips separation, is indicative of significant propeller rotation/engine power at impact. The airplane sustained substantial damage to the firewall.
NTSB Probable Cause Narrative
The pilot's improper aircraft weight and balance, and his failure to maintain sufficient airspeed to avoid a stall during takeoff-initial climb.
