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.

GAA18CA583
The pilot receiving instruction in the tailwheel-equipped airplane reported that, during landing, the airplane touched down abruptly. He added that he taxied to the edge of the runway and saw that the airplane was leaning left. The flight instructor reported that the pilot leveled off about 3 ft above the ground and allowed the airspeed to decrease. He added that he instructed the pilot to add power to "cushion the landing" and that the pilot attempted to do so, but the airplane continued to decelerate until it aerodynamically stalled and landed hard on the left main landing gear. The airplane sustained substantial damage to the fuselage. The instructor reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's receiving instruction’s improper landing flare and his failure to maintain adequate airspeed and his exceedance of the airplane's critical angle of attack during landing, which resulted in an aerodynamic stall.
