NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.
The pilot reported that the accident flight was a test flight after a recent annual inspection during which two engine cylinders were replaced. After he completed a preflight inspection, which included preheating the airplane, the pilot started the engine and allowed it to run for 45 minutes on the ground. After the ground run was complete, he inspected the engine for oil leaks before departure, and none were found. After takeoff, the pilot said he climbed the airplane to 900 feet above the ground, and as he leveled off, all engine power was lost. In an attempt to restart the engine, he applied carburetor heat and switched fuel tanks, but he was unable to restore engine power, and he selected an area of rough and uneven terrain as a forced landing site. During touchdown, the airplane sustained substantial damage to the empennage and fuselage. A postaccident examination revealed no evidence of preimpact mechanical anomalies that would have precluded normal operation. During a subsequent engine run, the engine started and ran normally. According to a Federal Aviation Administration carburetor icing chart, given the temperature and dew point at the time of the accident, carburetor ice was likely at glide and cruise power settings. It is likely that, as the pilot leveled off and reduced engine power, carburetor icing formed, causing the engine to lose power.
The National Transportation Safety Board determines the probable cause(s) of this accident to be: The loss of engine power due to carburetor icing and the pilot's failure to apply carburetor heat when he reduced engine power. Full narrative available
