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
CEN09CA273
The instructor pilot was performing flight checks on the single-engine helicopter after maintenance had been performed. The instructor pilot and private pilot on board had completed three straight-in autorotations and one 180-degree reverse direction autorotation. The instructor set up on downwind and initiated a second 180-degree autorotation. When the turn was almost completed, the rotor RPM started to drop. The instructor decided to initiate a power recovery go-around. Power was applied but the helicopter continued to settle and hit the ground in a level attitude. The helicopter rolled on its left side and sustained substantial damage. Both occupants exited the aircraft unassisted and were not injured. No system anomalies were discovered.
NTSB Probable Cause
The pilot's failure to maintain adequate main rotor rpm during a practice autorotation. Contributing to the accident was the instructor pilot's delayed remedial action.
