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 private pilot reported that during a local flight in the aerobatic biplane, he performed an aerobatic flight maneuver about 2,000 feet above ground level. He reported that he performed a left wing over, the airplane entered an unintentional spin and he recovered from the spin too low to the ground. The airplane impacted trees and came to rest upright, but sustained substantial damage to both wings, fuselage and empennage. The pilot reported that there were no mechanical malfunctions or anomalies with the airplane during the flight that would have prevented normal flight operations.
NTSB Probable Cause
The pilot's loss of control while performing an aerobatic maneuver resulting in an inadvertent spin and collision with trees and terrain.
