NTSB narrative
THE HELICOPTER ROLLED OVER AS IT WAS LIFTING OFF FROM A TRANSPORT TRAILER. A POST-CRASH EXAM REVEALED THAT THE LEFT REAR TIE-DOWN STRAP ON THE TRAILER WAS WRAPPED AROUND ONE OF THE HELICOPTER SKIDS. THE GROUND CREWMAN BELIEVED HE HAD REMOVED ALL OF THE STRAPS PRIOR TO THE ATTEMPTED TAKEOFF. THE PLT STATED HE HAD VISUALLY CHECKED ALL TIE-DOWN STRAPS DURING HIS PREFLT. HOWEVER, THERE WAS EVIDENCE THE LEFT REAR TIE-DOWN STRAP (WHICH WAS ATTACHED TO THE TRAILER) HAD NOT BEEN UNHOOKED PROPERLY. THE PLT ACKNOWLEDGED THAT A HANDS-ON INSPN OF THE STRAP MAY HAVE PREVENTED THE OCCURRENCE.

- 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 1987-06-14.
