NTSB narrative
The CFI stated that while in the traffic pattern he reduced the throttle to idle to simulate loss of engine power, but he did not apply carburetor heat. The student hesitated in performing the emergency procedures, then applied carburetor heat 20-30 seconds later. The CFI aborted the simulation and added power but the engine failed to respond. He made a forced landing on a golf course and the airplane collided with a tree. The engine was subsequently started, but was not operated to full rated RPM due to damaged engine mounts. A review of the carburetor ice probability chart revealed that serious carburetor icing conditions were probable at descent power about the time of the accident.
Probable cause
the failure of the pilot-in-command to apply caburetor heat before reducing the throttle to simulate an engine failure. Contributing to the accident was the carburetor icing conditions and the unsuitable terrain encountered during the emergency descent.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
