Fort Worth Spinks Airport
Aircraft Accident/Incident Report

Fort Worth, Texas 76028
Thursday, July 28, 2011 16:50 CDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said that the engine began to run rough after he leveled off from a descent, and shortly thereafter, it rolled back to idle power. The pilot established a glide to the nearest airport and attempted to troubleshoot the cause of the loss of power, but power was not restored, and he made a forced landing to a cornfield short of the runway. A postaccident examination of the carburetor and a test run of the engine revealed no evidence of pre-mishap mechanical deficiencies. The weather conditions at the time of the power loss were conducive to carburetor icing at glide and cruise power. The airplane was not equipped with carburetor heat.

NTSB Probable Cause Narrative

A total loss of engine power due to carburetor icing.
