NTSB narrative
The commercial pilot was approaching an off-shore oil platform and positioned the helicopter to land "into the wind." The intended flight path crossed over a crane with a windsock on top. Having observed the obstructions, the pilot continued the approach to the helideck. As the helicopter overflew the crane, the helicopter's tail rotor contacted the windsock, resulting in substantial damage to the helicopter's tail boom section. The pilot was able to land the damaged helicopter on the oil platform's helideck.
Probable cause
The pilot's failure to maintain clearance from the windsock during the approach.

Source notes (4)
- 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, coordinates. 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.
