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 pilot reported that he taxied the airplane to take off, but experienced a radio issue and subsequently decided to taxi back to an area near a group of hangars to troubleshoot the radio. While taxiing, the pilot attempted a right turn towards an opening between two hangars. The airplane’s wings struck each hangar on both sides of the airplane and sustained substantial damage. The operator reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
