Pine Bluff, AR, USA
N8984B
Cessna 172
The pilot was flying the airplane at 1,200 feet agl, looking at the ice damage caused by a recent storm. As the airplane was crossing plowed fields, which were surrounded by trees, the engine rpm "dropped to around 1100." The pilot "pushed the fuel mixture all the way to rich, pulled the carburetor heat control, pushed off the cabin heat and pushed the throttle all the way forward," with no increase in engine performance. A forced landing was initiated to a gravel road. During the landing roll, the airplane drifted off the left side of the road into a muddy ditch. The airplane nosed over and came to rest inverted. The pilot reported that the loss of engine power was due to carburetor icing.
