Cook Airfield Airport
Aircraft Accident/Incident Report

Rose Hill, Kansas 67037
Wednesday, May 9, 2012 12:00 CDT

NTSB Narrative Summary Released at Completion of Accident

The amateur-built airplane's engine lost power after takeoff, and the pilot performed an off-airport landing. The airplane struck trees during the landing. A postaccident examination revealed no evidence of mechanical malfunctions or failures that would have precluded normal operation. The temperature and dew point about the time of the accident were favorable for carburetor icing. Further, the Ford Model A engine that was installed on the airplane is noted for its susceptibility to the formation of carburetor ice. Additionally, the pilot reported his belief that the carburetor heat system of the airplane was ineffective at flight speeds and that the loss of power was due to the formation of carburetor ice.

NTSB Probable Cause Narrative

The loss of engine power due to carburetor icing.
