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.

The 5,740-hour commercial pilot lost control of the single-engine helicopter while maneuvering during an aerial application flight. The pilot stated, that he made a right turn into the wind and that a gust of wind "must have hit the tail causing him to lose tail-rotor authority." The pilot further stated that he corrected with full left pedal; however, the helicopter touched down and the left skid dug into the soft ground causing the aircraft to roll onto the left side. At the time of the accident, the wind was reported from 240 degrees at 4 knots, gusting to 12 knots. The pilot reported having accumulated 70 hours in the same make and model. He added that there were no anomalies with the helicopter prior to the accident.

NTSB Probable Cause

The pilots encounter with loss of tail rotor effectiveness during an aerial application flight. A contributing factor was the gusty winds.
