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.

While performing a main wheel landing on runway 34, the pilot said that the airplane bounced once, and then 'swerved right.' He said that he applied a 'strong correction to the left to bring the airplane's nose back to the centerline.' The airplane subsequently ground looped to the left. Postaccident examination of the right main tire disclosed that its inner tube had failed.

NTSB Probable Cause

The failure of the right main landing gear tire's inner tube, and the subsequent inadvertent ground loop by the pilot.

Visual meteorological conditions prevailed for the cross-country flight which originated from Elko, Nevada, approximately 1 hour before the accident. A VFR flight plan had been filed. The pilot reported that while performing a main wheel landing on runway 34, the airplane bounced once, and then "swerved right." He said that he applied a "strong correction to the left to bring the airplane's nose back to the centerline." The airplane subsequently turned left damaging the right aileron and right rear spar. Postaccident examination of the right main tire by the pilot disclosed that its inner tube had failed.
