Event Details

The aircraft executed a forced landing approximately one mile southwest of a stopping point that the pilot had added to the flight plan. The pilot decided to add this stop after observing a lower than planned groundspeed, prompting concern about fuel availability. During the flight, the aircraft encountered icing conditions. To manage the icing, the pilot used carburetor heat. The flight involved climbs and descents to avoid weather for about an hour and a half, during which the carburetor heat was continuously used, enriching the fuel-air mixture.

Fuel Quantity After Landing

Following the forced landing, an inspection of the aircraft's fuel tanks revealed approximately three gallons of fuel remaining. The left tank contained two gallons, and the right tank contained one gallon.
