NTSB narrative
THE PILOT WAS RETURNING FROM HIS RANCH NEAR EDOM EN ROUTE TO THE REDBIRD AIRPORT IN DALLAS WHERE THE HELICOPTER WAS NORMALLY HANGARED. THE PILOT HAD BEEN WORKING AT HIS RANCH WITH THE FOREMAN, AND THEY HAD CONSUMED ALCOHOL DURING THE DAY WHILE THEY WERE WORKING. WITNESSES OBSERVED THE HELICOPTER FLYING AT LOW ALTITUDE NEAR THE ACCIDENT SITE. THE HELICOPTER WAS ALSO SEEN DESCENDING INTO OPEN FIELDS AND BEHIND TREE LINES, AND WAS SEEN SECONDS LATER CLIMBING TO ALTITUDE. THE HELICOPTER SUBSEQUENTLY IMPACTED THE GROUND IN AN APRX 60 DEG LEFT BANK. THE PILOT AND HIS DOG WERE JETTISONED FROM THE HELICOPTER DURING IMPACT. THE PILOT WAS FOUND CLUTCHING A CELLULAR PHONE IN HIS RIGHT HAND. THE PILOT'S BLOOD ALCOHOL LEVEL WAS 248 MG/DL.
Probable cause
THE PILOT'S FAILURE TO MAINTAIN CONTROL OF THE HELICOPTER AS A RESULT OF HIS PHYSICAL IMPAIRMENT DUE TO ALCOHOL. FACTORS CONTRIBUTING TO THE ACCIDENT WERE: THE DARK NIGHT AND THE PILOT'S LIKELY DIVERSION OF HIS ATTENTION FROM OPERATING THE HELICOPTER.

- 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: local date, investigation status. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1992-12-12.
