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.

The initial touchdown and landing roll were uneventful, and the pilot applied light pressure on the brakes. He felt the initial deceleration, and then thought that the left brake appeared to operate unevenly with the right brake. At the same instant, the right wing rose off the ground, and the right brake was thus ineffective. The airplane swerved hard to the left. The pilot applied right rudder and right brake as the right wing settled back to the ground; however, the airplane departed the runway surface. The left wing collided with a taxiway sign and sustained substantial damage.

Full Narrative

The initial touchdown and landing roll was uneventful, and the pilot applied light pressure on the brakes. He felt the initial deceleration, and then thought that the left brake grabbed. At the same instant, the right wing rose off the ground, and the right brake was thus ineffective. The airplane swerved hard to the left. The pilot applied right rudder and right brake as the right wing settled back to the ground; however, the airplane departed the runway surface. The left wing collided with a taxi way sign, and sustained substantial damage. The impact turned the airplane into the grass median. The pilot then taxied uneventfully to parking.
