NTSB narrative
According to the pilot, he had just performed an uneventful landing in his pasture and was allowing the engine to cool down before shutting it down. The pilot reported that one minute into the cool down, he reduced the throttle to seventeen hundred rpm. He felt heat on his back and turned around to see fire coming from the engine. As the pilot was attempting to egress from the helicopter, he fell backwards, grabbed the cyclic stick with the engine still running, and pulled it to the left side as he slid out. The helicopter was entirely consumed by fire. Due to the extent of the damage, the origin of the fire could not be determined.
Probable cause
engine fire for reasons undetermined.

- 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.
