Aircraft involved
Probable cause & findings
A total loss of engine power due to carburetor icing during final approach, which resulted in a hard landing short of the runway and the nose landing gear collapsing.
Factual narrative
The pilot reported that, during final approach, the engine sputtered then had a total loss of power. The airplane landed short of the runway on the threshold, and the nose landing gear collapsed. The airplane sustained substantial damage to the engine truss and mount. A postaccident examination by a Federal Aviation Administration (FAA) airworthiness inspection did not show any evidence of preimpact mechanical malfunction or abnormalities. A photograph provided by the inspector, shows no damage to the propeller, which is consistent with the engine not producing power at the time of impact. He added that fuel was present in the tanks and that the gascolator screen was found clear of debris, and he suspected carburetor ice was responsible for the loss of engine power. The automated weather observation station located on the airport reported that, about the time of the accident, the wind was 310° at 7 knots, 7 statute miles, temperature 72°F, dew point 48°F. The airplane landed on runway 34R. According to the Carburetor Icing Probability Chart (refer to docket) and based on the temperature and dew point about the time of the accident, the conditions were favorable for serious carburetor icing at decent power setting. After multiple attempts, the pilot did not submit the National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report Form 6120.1. The pilot reported that, during final approach, the engine sputtered and then lost all power. The airplane landed short of the runway on the threshold, and the nose landing gear collapsed. The airplane sustained substantial damage to the engine truss and mount. Postaccident examination by a Federal Aviation Administration inspector revealed no evidence of preaccident mechanical malfunctions or failures that would have precluded normal operation. 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. The inspector reported that fuel was present in the tanks, that the gascolator screen was found clear of debris, and that he suspected carburetor ice was responsible for the loss of engine power. The airport's automated weather observation station reported that, about the time of the accident, the wind was from 310° at 7 knots, the temperature was 72°F, and the dew point was 48°F. The atmospheric conditions were favorable for serious carburetor icing at descent power setting. Source: NTSB Aviation Accident Database Retrieved: 2026-02-12
