NTSB narrative

Because of falling snow and low ceilings, the pilot, who did not hold an instrument rating, was intentionally flying very low over the surface of an open area of flat/glassy water in whiteout/greyout conditions. As he continued on toward his destination, he kept getting lower and lower in order to maintain visual reference with the water's surface. Eventually the helicopter's skids drug through the water, followed almost immediately by the tail rotor colliding with the water, and soon thereafter by the helicopter's airframe impacting the water's surface.

Probable cause

The pilot's failure to maintain clearance from the surface of an open body of water while intentionally attempting to maintain a very low altitude while in cruise flight. Factors include falling snow, low ceilings, whiteout/greyout conditions, and flat/glassy water.

  • 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.
