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 solo commercial certificated pilot was conducting a low pass over a beach looking for an appropriate landing spot for the helicopter under Title 14, CFR Part 91, when the accident occurred. In a written statement, the pilot reported he was making a low pass over the landing area when a sudden gust of wind caused the helicopter to pitch up, and the tail rotor struck an unknown object. He reported that the helicopter yawed to the right, descended, and the skid struck the ground. According to the pilot, the helicopter came to rest upright, but sustained damage to the main rotor system, tail cone, and rotor mast, in addition to the tail rotor. He reported there were no known mechanical problems with the helicopter prior to the accident.
NTSB Probable Cause
The pilot's inadequate compensation for wind gusts while maneuvering, which resulted in the tail rotor striking an undetermined object, and an emergency descent and landing. Factors contributing to the accident were the wind gusts, and the failure of the tail rotor system.
