NTSB narrative
The helicopter was operating with a 25 foot long-line at the time of the accident. The pilot was returning to pick up another load of Christmas trees, maneuvering at slow speed looking for the hooker, when he heard a loud bang and the aircraft began to spin rapidly. More bangs were heard from the rear of the aircraft as it continued to spin. The pilot rolled the throttle to idle, which did not arrest the spin. The aircraft then entered a nose-low attitude while spinning; the pilot could not get the nose up with full aft cyclic. Just prior to ground impact, the pilot rolled the throttle to full open, which brought the nose up to a near-level attitude. The helicopter impacted the ground level, but sliding to the left into a hillside. Terrain was described as small rolling hillsides with various fields of small to large Christmas trees. FAA inspectors found evidence of white paint transfer on the long-line cable, and also signatures consistent with cable marks on one of the two separated tail rotor blades. Witnesses noted that ground fog was forming in the area at the time of the accident.
Probable cause
Failure of the pilot to maintain ground clearance, resulting in the long-line snagging and then striking the tail rotor.

- 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.
