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 flight instructor and his student were conducting an instructional flight in the airport traffic pattern when the airplane collided with multiple geese during initial climb. Due to the collision, the engine experienced a loss of engine power, so the flight instructor continued straight ahead. He conducted a forced landing on a golf course and the airplane nosed over. The airplane sustained substantial damage to the fuselage, empennage, and both wings.
