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 during an instrument landing system (ILS) instrument approach in instrument meteorological conditions, she descended into fog about 1,000 feet above ground level. The pilot continued the approach beyond the minimum descent altitude and stated that she did not see the runway or runway environment until she was beyond the 1,000-foot runway markings, and realized the airplane had drifted right of the runway. The pilot attempted to maneuver the airplane towards the runway, however, it landed hard, in a grassy, mud covered area, off the right side of the runway. Postaccident examination of the airplane revealed the fuselage was structurally damaged. The pilot reported no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
