NTSB summary

HISTORY OF FLIGHT On September 5, 2011, about 1833 central daylight time, a Socata TBM 700, N850SY, impacted terrain near Mount Pleasant, Wisconsin, during a forced landing following a loss of engine power. The pilot was fatally injured. The airplane was registered to Green Plane LLC, and operated by the pilot under the provisions of 14 Code of Federal Regulations (CFR) Part 91 as a personal flight. Visual flight rules (VFR) conditions prevailed for the flight, which operated on an instrument flight rules (IFR) flight plan. The flight originated from the Central Wisconsin Airport (CWA), Mosinee, WI, about 1626, and the intended destination was the Waukegan Regional Airport (UGN), Waukegan, Illinois. GPS track data, retrieved from the Garmin G1000 avionics system on the airplane, depicted the airplane departing CWA about 1626. The airplane remained in the CWA traffic pattern, performing two full stop landings at CWA prior to proceeding toward UGN. At 1653, the airplane took off from runway 8 at CWA and then proceeded southeast for about 5 nautical miles then south for 12 nautical miles where it crossed the Stevens Point Airport (STE) at an altitude of about 12,000 feet mean sea level (msl). After crossing STE, the airplane turned southeast to a heading of 130 degrees. During this portion of the flight, the airplane was in a climb reaching an altitude of about 19,000 feet msl at 1703:15. Data retrieved from the G1000 indicated that during the climb portion of the flight the roll angle and lateral acceleration were neutral. This indicated that the rudder trim was appropriately

Probable cause

The pilot’s failure to properly trim the airplane’s rudder during cruise flight, which resulted in a prolonged uncoordinated flight condition, unporting of the fuel tank feed line, and subsequent fuel starvation and engine power loss. Contributing to the accident was the pilot’s failure to feather the engine’s propeller and maintain a proper glide airspeed following the loss of engine power.
