- Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
- Part 91: General Aviation

- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Loss of engine power (total)
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The sport pilot reported that, as he was approaching the landing runway, he retarded the throttle and descended from 1,300 to 1,000 ft mean sea level. He added that, a few seconds after retarding the throttle, the engine "ran rough" for a few seconds and then lost all power and would not restart. He did not attempt to apply carburetor heat, configured the airplane for best glide speed, and maneuvered for a forced landing on a golf course. After landing, the left wing struck a tree.
Postaccident examination of the airframe and engine revealed no evidence of preimpact mechanical failures or malfunctions that would have precluded normal operation, and there was sufficient fuel onboard at the time of the accident. A test run of the engine revealed no anomalies. Given that the weather conditions at the time of the accident were conducive to serious carburetor icing at glide power and the pilot chose not to apply carburetor heat after the engine initially lost power, it is likely that the engine lost power due to carburetor icing.
Probable cause
The pilot's failure to apply carburetor heat following a loss of engine power due to carburetor icing.

- 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.
