Cessna 150K N6032G accident near Gaylord, Michigan

Probable cause

A loss of engine power for undetermined reasons.

NTSB analysis

The pilot reported that he was on a local flight and the engine gradually lost power. He performed the checklist for a loss of engine power and the airplane did not regain full power. The pilot then chose an emergency landing field, extended full flaps, and the engine "quit." As the pilot pumped the throttle, the engine restarted and the airplane started to climb. The engine lost power again and the pilot chose another field. During the forced landing, the airplane nosed over. After the accident, the engine ran during a subsequent test run. The pilot reported that a cup of water was removed from the right fuel tank sump and a quarter cup from the front sump during the airplane preflight. The local airport's temperature and dew point were plotted on the carburetor icing chart listed in Special Airworthiness Information Bulletin CE-09-35, and their intersection fell in the “serious icing (glide power)” range.
