What happened
During a night climb following takeoff, the pilot reported that the engine began to sputter. Suspecting that there might be water in the fuel, the pilot elected to land across rows in a field. During the landing process, the landing gear failed, causing the aircraft to come to rest on its belly. The impact resulted in a bent propeller, torn fabric, and damage to the engine cowling.
While the owner initially believed the damage was minor, an inspection by an FAA inspector later determined the damage to be substantial. Additionally, the aircraft sustained further damage when an attempt was made to move it using a forklift.
The investigation
The investigation found no evidence of preimpact part failure or malfunction. However, the aircraft had been moved prior to the commencement of the investigation. Meteorological data indicated a temperature of 78 degrees and a dew point of 68 degrees. According to icing probability charts, these atmospheric conditions were conducive to carburetor ice formation.
