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 student pilot, he entered the downwind leg for the runway as instructed by the tower controller. The airplane was stabilized on final approach, but the student pilot initiated the landing flare too late, resulting in a hard landing. As he turned onto the taxiway to complete the after-landing checklist, he discovered that the nosewheel tire had deflated. A postaccident examination revealed that the firewall and floorboard panels were wrinkled. The student pilot reported no preaccident anomalies or failures that would have prevented normal operation of the airplane.

When he passed his aiming (touchdown) point, he initiated a descent. The airplane was stabilized on final approach, but when the student pilot went to land, he flared too late, resulting in a hard landing. The student pilot turned onto the taxiway to do an after-landing checklist and discovered the nose wheel tire was deflated. A postaccident examination revealed that the firewall and floorboard panels were wrinkled. The student pilot reported no preaccident anomalies or failures that would have prevented normal operation.
