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, when the airplane touched down on the runway, he felt a vibration followed by the airplane pulling to the left. The pilot added right brake in attempt to realign the airplane; however, it continued to the left and exited the left side of the runway. The airplane traversed over the gravel adjacent to the runway and into brush, where it came to rest. A postaccident examination of the airplane revealed that the airplane’s left main landing gear tire was flat. No other anomalies were noted that would have precluded normal flight.

NTSB Probable Cause

The pilot’s failure to maintain directional control during the landing roll, as a result of a flat left main landing gear tire.
