The NTSB's narrative final · quoted from the NTSB record
The pilot reported that he planned to accomplish a power-off landing to the runway and reduced engine power to idle during the descent from 9,000 feet to the traffic pattern altitude (3,700 feet). On final approach to the runway, the pilot applied carburetor heat. Shortly thereafter, the airplane descended below the glide path and the pilot increased engine power in an effort to correct the situation. The engine did not respond to the pilot’s inputs, and he subsequently landed short of the runway. The pilot reported that he suspected carburetor icing and that he should have applied carburetor heat immediately after retarding the throttle. However, the ground temperature and dew point at the time of the accident did not fall within the carburetor icing range. Postaccident examination of the engine and airframe revealed no preaccident mechanical malfunctions or failures that would have precluded normal operations.
