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.
Chino, CA
The pilot of a tailwheel-equipped airplane reported that he was doing S-turns while taxiing and that he did not see any airplanes in the run-up area. While positioning the airplane in the run-up area, his airplane's left wing collided with the propeller of a stopped airplane. The pilot of the stopped airplane reported that, after completing a run-up and waiting for a clearance to depart, he saw a "warbird" entering the run-up area. The other airplane continued straight, and the left wing collided with his airplane's propeller. The tailwheel-equipped airplane sustained substantial damage to the left wing. Both pilots reported that there were no preimpact mechanical failures or malfunctions with their airplanes that would have precluded normal operation.

The pilot of a tailwheel-equipped airplane reported that, he was doing S-turns while taxiing due to the restricted forward visibility and did not see any airplanes in the run-up area. While positioning the airplane in the run-up area, the left wing collided with the propeller of a stopped airplane. The pilot of the stopped airplane reported that, after completing a run-up and waiting for a clearance to depart, he observed a "warbird" entering the run-up area. The other airplane continued straight, and the left wing collided with their propeller. The tailwheel-equipped airplane sustained substantial damage to the left wing. The pilots of the tailwheel-equipped airplane and the stopped airplane reported that there were no preimpact mechanical failures or malfunctions with their respective airplanes that would have precluded normal operation.
