Flight and Maneuver
After takeoff, the certified flight instructor (CFI) flew to another airport with a student to demonstrate simulated loss of engine power. The CFI reduced power and applied carburetor heat, then initiated a right descending turn. During the descent, he reported clearing the engine—verifying full power availability—at least once, but noted that the engine should not have been left at a low idle for more than one minute.
Approach and Go-Around
Approaching runway 02, the CFI lowered 10 degrees of flaps while on a short base leg. The approach appeared normal to slightly high. On short final, about 100 feet above the touchdown zone elevation, the flight encountered a very strong and turbulent gust or rotor, requiring immediate full power. The CFI applied power, but the engine hesitated or stumbled. He removed carburetor heat, pushed forward on the throttle and mixture controls, and pumped the throttle in an unsuccessful attempt to restore engine power.
Landing and Inspection
Maneuvering to a clear space, the CFI landed the airplane in a wooded area. Following recovery, a Federal Aviation Administration (FAA) airworthiness inspector examined the engine and found no evidence of preimpact mechanical failure or malfunction.
Weather Conditions
A surface observation weather report approximately 17 minutes before the accident indicated the temperature and dew point were 18°C and 13°C (64°F and 55°F), respectively. According to FAA Special Airworthiness Information Bulletin (SAIB) CE-09-35, dated June 30, 2009, these conditions were favorable for serious icing at glide power.
