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.

NTSB Number
GAA19CA517
The pilot reported that, before takeoff, he adjusted his seat. During takeoff, his seat slid back, and he was not able to reach the rudder pedals or throttle lever. The airplane accelerated, veered left, exited the runway to the left, ground looped, and impacted a berm. The airplane sustained substantial damage to the right wing. The pilot 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 failure to properly secure the seat before takeoff, which resulted in it sliding back during takeoff and rendering him unable to reach the rudder pedals and throttle lever, a subsequent runway excursion, ground loop, and impact with a berm.
