Event Summary
During a training flight, an instructor reduced engine power and asked the pilot to demonstrate a simulated forced landing. After the pilot completed the procedure, full throttle was applied, but the engine did not respond. The instructor assumed control of the airplane and performed a landing on uneven terrain, during which the airplane overturned.
Examination
Following the incident, the engine was tested and operated normally. The instructor and pilot later stated that carburetor heat had not been applied before the power reduction, and they attributed the power loss to carburetor ice. A subsequent functional test conducted by an FAA coordinator also found the engine to run normally.
No further details regarding injuries, damage, or aircraft type were provided in the source.
