NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.
The pilot reported that, before the helicopter tour flight, passengers had been briefed, but still attempted to take cell phones onboard without "a case". He then supplied the cases and attached them to the passengers wrist. During the flight, while at approximately 100 knots, the right side passenger extended her cell phone, in the case, outside of the cabin into the airflow. The cell phone and case, minus the strap, departed the helicopter and impacted the tail rotor.
