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 solo student pilot reported that on his second supervised solo landing touchdown, the airplane landed flat and firm. He further reported that the airplane "roared" then veered off the runway to the left, and stopped abruptly after the nose wheel became stuck in mud. The student pilot further reported that he may have accidently advanced the throttle after he was pushed forward during the flat landing. According to the student pilot there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. A postaccident examination revealed substantial damage to the firewall.
NTSB Probable Cause
The student pilot's inadequate flare which resulted in a hard landing, loss of directional control, and a runway excursion.
