Event Description
The pilot reported that during final approach the engine sputtered and then experienced a total loss of power. The airplane subsequently landed short of the runway threshold, and the nose landing gear collapsed. The airplane sustained substantial damage to the engine truss and mount.
Postaccident Examination
A postaccident examination conducted by a Federal Aviation Administration (FAA) airworthiness inspector did not reveal any evidence of preimpact mechanical malfunction or abnormalities. A photograph provided by the inspector showed no damage to the propeller, which is consistent with the engine not producing power at the time of impact. Fuel was present in the tanks, and the gascolator screen was found clear of debris. The inspector suspected that carburetor ice was responsible for the loss of engine power.
Weather and Carburetor Icing Conditions
The automated weather observation station at the airport reported that around the time of the accident, the wind was from 310° at 7 knots, visibility was 7 statute miles, temperature was 72°F, and the dew point was 48°F. The airplane landed on runway 34R. According to the Carburetor Icing Probability Chart (refer to the docket), based on the temperature and dew point conditions, serious carburetor icing at descent power setting was likely.
Other Information
After multiple attempts, the pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1.
