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.

According to the pilot in the tailwheel-equipped airplane, this was his first solo flight in the airplane. During the landing roll, the airplane decelerated and veered to the left. The pilot reported that he overcorrected, and the airplane veered to the right. The airplane exited the runway, and the left wing struck the ground during the right ground loop. The airplane sustained substantial damage to the left-wing spar and aileron. The METAR at the accident airport reported that, about the time of the accident, the wind was calm, and the sky was clear. The pilot noted in the National Transportation Safety Board's Pilot Aviation Accident Report Operator/Owner Safety Recommendation section that this type of accident could have been prevented if he had "flown with a properly rated pilot (tailwheel endorsed) and practiced landings before flying…solo." The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

NTSB Probable Cause

The pilot’s failure to maintain directional control during the landing roll. Contributing to the accident was the pilot’s failure to obtain appropriate training in the airplane before flying solo.

Full Narrative

According to the pilot in the tailwheel-equipped airplane, this was his first solo flight in the airplane. During the landing roll, the airplane decelerated and veered to the left. The pilot reported that he over corrected and the airplane veered to the right. The airplane exited the runway and the left wing struck the ground during the right ground loop. The airplane sustained substantial damage to the left-wing spar and aileron. The METAR at the accident airport, reported that about the time of the accident, the wind was calm, and the sky was clear. The National Transportation Safety Board's Pilot Aviation Accident Report identified in the Operator/Owner Safety Recommendation Section, that this type of accident could have been prevented if he had, "flown with a properly rated pilot (tailwheel endorsed) and practiced landings before flying… solo." The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
