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 pilot of the tailwheel-equipped airplane reported that he made a normal three-point landing, shortly after touchdown the airplane veered to the left, then veered to the right. The pilot further reported that he applied power in an attempt to regain control, however the airplane veered back to the left and he reduced power as the airplane departed the runway. The airplane ground looped and the right wing impacted terrain causing substantial damage to the right aileron. The pilot reported there were no preimpact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.

NTSB Probable Cause

The pilot's failure to maintain directional control upon landing, which resulted in a runway excursion followed by impact with terrain.
