NTSB Narrative Summary Released at Completion of Accident

During cruise flight at 3,000 feet msl, the engine began to sputter, and lost all power. The student pilot completed the emergency checklist items, which included the application of carburetor heat. Subsequently, the student pilot was able to restart the engine. The engine then ran for approximately 15-20 seconds, but lost all power a second time; shortly after the student pilot had turned the carburetor heat off. The student pilot again was able to restart the engine using emergency procedures, which included turning the carburetor heat back on. The engine restarted and ran at a slower rpm for approximately 1 minute, before losing total power for a third time. The student pilot then performed a forced landing into trees. Review of the aircraft and fueling records revealed that the airplane had flown 3.3 hours since being completely fueled. Review of a make and model Pilot's Operating Handbook revealed that at 65 percent power, the airplane's endurance was approximately 3.9 hours. Review of the FAA Carburetor Icing Probability Chart revealed that the airplane engine was susceptible to icing at glide and cruise power in the reported weather conditions.

NTSB Probable Cause Narrative

The student pilot's improper use of carburetor heat, which resulted in a total loss of engine power during cruise flight. A factor was carburetor icing conditions.
