What happened
The pilot was operating a Cessna aircraft on a flight returning to the landing strip. During this phase of flight, the engine suddenly lost power and would not restart. In response to the emergency, the pilot attempted an emergency landing in the immediate vicinity.
During the landing sequence, the aircraft struck a ditch that was concealed by tall grass. The impact caused the aircraft to nose over, resulting in significant damage to the airframe. The specific registration of the aircraft involved in this incident is N12345.
The investigation
Following the accident, an examination of the engine components was conducted to determine the cause of the power loss. The inspection focused on the carburetor assembly, which showed signs of significant wear and structural failure.
The examination revealed three distinct cracks in the float of the carburetor. Additionally, there was noticeable wear on several critical internal components, including the shaft, bushings, mixture control flange, and the float needle. These mechanical failures likely contributed to the engine's inability to maintain power or restart.
Findings
The primary factors leading to the accident were the loss of engine power during the return flight and the subsequent impact with terrain during the emergency landing. The presence of a hidden ditch obscured by vegetation played a critical role in the severity of the outcome, causing the nose-over condition. The mechanical defects found in the carburetor indicate that maintenance issues may have been a contributing factor to the initial engine failure.
