The NTSB's narrative final · quoted from the NTSB record
The pilot reported that, while the airplane was level at 15,000 feet in instrument meteorological conditions, he failed to apply carburetor heat to the engine. After several minutes, the engine began losing power, and the airplane was not able to sustain flight. During the descent for a forced landing in mountainous terrain, the airplane descended below the cloud base about 2,000 feet above the ground, and the pilot observed a road and a clearing. During the landing rollout, the airplane impacted trees, which severed its wings. Icing probability charts indicated that carburetor ice was probable under the atmospheric conditions in which the airplane had been flying. The pilot reported that if he had applied the carburetor heat during flight, the accident likely would not have occurred.
