The pilot and flight instructor were practicing takeoffs and landings near Richland Center, Wis. During the fourth takeoff, the engine started running roughly and losing power; it then stopped producing power.
They subsequently conducted a forced landing to a field. The Zodiak 601XL sustained substantial damage to the nose landing gear.
Both wing fuel tanks contained fuel. An examination of the airframe, engine, and related systems revealed no anomalies that would have precluded normal operation.
The temperature and dew point at the time of the accident were conducive to the accumulation of carburetor icing at glide and cruise power settings. Therefore, it is likely that carburetor ice accumulated during the landing and was present at takeoff, which resulted in the loss of engine power.
The National Transportation Safety Board determined the probable cause of this accident as the loss of engine power due to carburetor icing.
