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 on the controls in the left seat, the right seat pilot was familiarizing him with the airplane. The airplane bounced during landing on the runway. During the landing roll, the airplane veered left, and he overcorrected to the right, followed by an overcorrection to the left. He applied heavy braking, and the airplane turned 120° to the right. The side load on the left main landing gear tire resulted in it bursting. The wheel rim then dug into the runway, the airplane bounced, the tailwheel assembly failed, and the tail spring steel strut then dug into the soft surface. The airplane sustained substantial damage to the aft fuselage and the empennage.
NTSB Probable Cause
The pilot's improper landing flare, which resulted in a bounced landing, and his subsequent failure to maintain directional control, which resulted in the left main landing gear tire bursting and the tailwheel assembly failing.
Full Narrative
Both pilot's onboard the airplane reported that the purpose of the flight was to familiarize the pilot in the left seat with the airplane, of which he was appropriately rated yet had never flown. According to the pilot on the controls in the left seat, the tailwheel-equipped airplane bounced during landing on the asphalt runway. During the landing roll, the airplane veered to the left and he overcorrected to the right, followed by an overcorrection to the left. He applied heavy braking and the airplane turned 120° to the right and exited the right side of the runway. The left main landing gear tire deflated, and the wheel dug into the dirt surface. The airplane bounced, and the tailwheel-assembly failed and dug into the soft surface. The airplane sustained damage to the aft fuselage and the empennage.
