NTSB narrative
Witnesses observed the helicopter flying from north to south and collide with a 253-foot agl radio tower at about the 235-foot level. The main rotor blades partially separated and the helicopter descended uncontrolled to ground impact. The radio tower was depicted on aviation charts and was marked by an operational strobe light. The pilot had many years of operational experience in the area. Postmortem examination of the pilot showed he suffered from moderate chronic pulmonary emphysema and that he had a carbon monoxide level in the blood of about 26%. The pilot was reported to smoke about 1 pack of cigarettes daily. The 3 passengers did not have carbon monoxide in their blood. The source of the carbon monoxide level in the pilot could not be determined.
Probable cause
The pilot's incapacitation by carbon monoxide from undetermined sources which led to his diminished ability to see and avoid a radio tower.

- 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.
