NTSB narrative

The helicopter pilot reported that during an early morning flight, the visibility was good, but it was still dark.

The helicopter pilot reported that the helicopter climbed to about 300 ft above ground level and she noticed that her iPad was not showing her location. While attempting to fix the iPad, she inadvertently pushed the cyclic forward. She reported that when she re-focused her attention outside the helicopter, impact was imminent, and the helicopter impacted trees. The helicopter came to rest on its left side facing the opposite direction of travel.

The helicopter sustained substantial damage to the fuselage and the both rotor systems.

The pilot reported in the recommendation section of the National Transportation Board pilot aircraft accident report that the accident could have been prevented by not allowing herself to become distracted during flight.

The pilots reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

Probable cause

The pilot’s distraction due to her malfunctioning iPad, which led to her inadvertent forward cyclic application.

  • 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.
