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 student pilot and certified flight instructor were practicing full stop landings. As the airplane approached the runway, about 15 feet above ground level, the left wing suddenly dropped, and the airplane veered left. The airplane touched down hard on the left main landing gear, which collapsed. The right side then touched down hard, and the right main landing gear collapsed. A postaccident examination of the airplane revealed that the airframe buckled below the cockpit and was substantially damaged.

NTSB Probable Cause

The student pilot’s inadequate flare resulting in a hard landing. Contributing to the accident was the certified flight instructor's inadequate supervision.

Full Narrative

The student pilot and certified flight instructor (CFI) completed nine full stop landings. The wind was variable and increasing in intensity. As the airplane approached the runway, the left wing suddenly dropped at 15 feet above ground level, and the airplane veered left. It touched down hard on the left main landing gear, which collapsed. The right side then touched down hard, and the right main landing gear collapsed. The airframe buckled below the cockpit. After exiting the airplane, the student pilot noted a strong tail wind. The student pilot’s total time was 40 hours.
