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 taxied the ultralight airplane west between two rows of hangars up to the boundary of the non-movement area before stopping to contact ground control. At this time an Army Chinook helicopter made an approach to runway 34R before entering a hover over the runway in front of the pilot at an altitude estimated to be from 75 to 100 feet above ground level. As the helicopter descended to about 20 to 30 feet above ground level, the rotor wash from the helicopter picked the airplane up off the ground and blew it backwards and to the right. The airplane subsequently dropped to the ground on its right wingtip, coming to rest upright about 25 to 30 feet from where it was originally positioned. The airplane sustained damage to its right wing, including the flap and aileron, and the right main landing gear.
