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.

NTSB Number
WPR21LA083
The flight instructor of the tailwheel equipped airplane reported that, during an instructional flight, the student pilot’s landing flare was not sufficient to preclude a bounce. The student added power, and the airplane turned to the left toward hangars. The flight instructor took over the flight controls and continued the left turn to avoid hangars. The airplane departed the runway surface into a field. The wheels became stuck in the muddy ground and the airplane nosed over and came to rest inverted. The wings and vertical stabilizer were substantially damaged.
NTSB Probable Cause
The student pilot’s improper landing flare and loss of directional control and the flight instructor’s delayed remedial action resulted in a runway excursion and nose over.
