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.

CEN24LA216
The operator reported the pilot had completed the low-level aerial application work of applying liquid chemical to a grass field and the hopper was empty. During a right-hand turn, the pilot “turned too hard,” the airplane exceeded its critical angle of attack, which resulted in an aerodynamic stall and loss of airplane control at an altitude too low to allow for recovery. The airplane came to rest upright in a wheat field, a postimpact fire ensued, and the pilot was able to egress from the cockpit. The airplane was destroyed by the postimpact fire. The operator reported there were no preimpact mechanical malfunctions or failures with the airframe or the engine that would have precluded normal operation.
NTSB Probable Cause
The pilot’s exceedance of the airplane’s critical angle of attack during a low-level turn, which resulted in an aerodynamic stall and loss of airplane control at too low of an altitude to recover.
