Aircraft Accident/Incident Report

Ivins, Utah 84738
Friday, March 9, 2001 16:45 MST

NTSB Narrative Summary Released at Completion of Accident

The pilot said there was an intermittent loss of engine power during cruise flight . He suspected carburetor icing "since the Stromberg carburetor, standard [equipment] on the Ercoupe 415C, is prone to icing," and he immediately applied carburetor heat. The carburetor air temperature gauge indicated 10 degrees C. The engine "continued a pattern of power off/power on/power off in cycles of 4 or 5 seconds." He left the carburetor heat on but soon realized that his rate of descent left insufficient altitude to arrive at the destination airport. He landed on rough desert terrain, extensively damaging both wings and the nose and left main landing gears. According to the Carburetor Icing Graph, a temperature of 12 degrees C. and a dew point of 4 degrees C. [as reported by the nearest weather observation station] could result in serious icing at glide power, and a temperature of 10 degrees C. (as reported by the pilot) could result in serious icing at cruise power.

NTSB Probable Cause Narrative

The unsuitable terrain on which to make a forced landing. A contributing factors was the carburetor icing conditions.
