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, while on final approach to land, he decided to initiate a go-around. He applied full power and pitched up the airplane, which then stalled and turned left about 90°. The pilot was able to recover from the stall, but the airplane was close to the ground. Subsequently he landed the airplane in an open field. The student saw an irrigation ditch ahead and attempted to become airborne again, but the airplane did not gain sufficient lift and subsequently impacted the ditch. The airplane sustained substantial damage to the fuselage. The student reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

NTSB Probable Cause

The student pilot’s exceedance of the airplane’s critical angle attack during an attempted go-around, which resulted in an aerodynamic stall.
