Aviation safety reports, made easier to study
NTSB Reports is an independent research and search tool for public aviation accident and incident records. It brings NTSB aviation reports, structured fields, docket files, extracted figures, photos, videos, and update history into one searchable interface.
The goal is practical safety education: make it faster to find relevant investigations, compare similar events, review factual records, and understand the evidence behind probable-cause and preliminary reports.
The investigative work and source records belong to the National Transportation Safety Board and the published investigation record. This site is not affiliated with or endorsed by the NTSB.

NTSB Number
GAA19CA066
The pilot reported that, before the helicopter tour flight, he had briefed the passengers, but they still attempted to take cell phones onboard without cases. He then gave the passengers cases and attached them to their wrists. During the flight, while the helicopter was flying about 100 knots, the right-side passenger held her cell phone and case outside of the cabin into the airflow, which resulted in the cell phone and case without the strap exiting the helicopter and subsequently impacting the tail rotor. The helicopter sustained substantial damage to the tail rotor. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
NTSB Probable Cause
The passenger’s improper decision to hold her cell phone outside the helicopter, which resulted in it departing the helicopter and striking the tail rotor.
Full Narrative
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. The helicopter sustained substantial damage to the tail rotor. The pilot reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
