Overall Trends
Total, fatal, and serious accidents in the selected range.
Search investigations, review source evidence, monitor watched reports, and trace long-term patterns from one calm, data-first workspace.
Fast key and full-text search with live filters, watches, and precise metadata.
Use quotes for exact phrase matches (for example "fuel selector valve").
Track fatal and non-fatal accident patterns across Part 91, Part 135, and Part 121 operations.
Major cases, deep-report coverage, and investigation media across decades of NTSB history.
Move quickly by aircraft, airport, operator, and time with indexes built for research, not wandering.
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.
Palmer, AK
The pilot reported that she was departing from an area of mountainous, snow-covered terrain with flat light conditions. She said that after takeoff, while in a high hover, she made a left pedal turn on departure to avoid obstacles and other parked helicopters. As the helicopter was turning, an advisory light illuminated on the instrument panel. She focused her attention inside on the light and when she looked back outside everything appeared white and she lost all visual reference with the terrain. Subsequently the helicopter impacted the snow-covered terrain and rolled over to the left. The helicopter sustained substantial damage to the tailboom and fuselage. The operator reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
The pilot’s diverted attention during takeoff in flat light conditions, which resulted in a loss of visual reference with terrain.
