Read the full NTSB narrative

During descent about three nautical miles from the airport, the pilot noticed the engine rpm had dropped to approximately 1000. The pilot attempted to restore engine power, and within 30 seconds, the engine stopped completely. Examination of the airplane revealed fuel was recovered from the carburetor bowl, and from the fuel line between the fuel pump and the gascolator. Examination and test run of the engine revealed no evidence of mechanical malfunction. Review of published induction system icing probability data for the temperature and dew point reported at the time of the accident revealed the conditions fell within "visible icing at rated power" and "serious icing at glide power." The data charts state, "icing conditions within the limits of the 'visible icing' curves may become 'serious' after 15 minutes continuous operation in such conditions." Review of the Cessna Owner's Manual for the Model 177, revealed the "Let-Down" checklist states, (1) Mixture - Rich. (2) Power - As desired. (3) Carburetor Heat - As required to prevent carburetor icing."
