Cessna 120 N1881N accident near Hudson, Colorado

Probable cause

The partial loss of engine power for reasons that could not be determined based on the available information.

NTSB analysis

The pilot was attempting to land with quartering tailwind. He stated that he noticed a strong crosswind and decided to go around. During the go-around, the pilot added engine power; however, the engine did not develop full power. The engine began to sputter and surge as the airplane continued to climb but did not regain power, so the pilot performed a forced landing to a field. The airplane nosed over and sustained substantial damage.

A postaccident engine test run was performed. The engine started without hesitation, but damage to the engine and propeller prevented testing the maximum power setting. Although the engine operation during the go-around is similar to that which would be experienced if carburetor ice had accumulated during the approach, the weather conditions at the time were just outside those at which ice would accumulate. Therefore, the reason for the partial loss of engine could not be determined.
