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
GAA16CA052
During a night flight, the pilot reported that after he landed on the runway, he slowed the airplane to taxi speed, and continued to the taxiway turnoff. The pilot misidentified the taxiway turn and turned off the runway into a grass area between the runway and taxiway. The pilot reported that the grass area had a downslope that led to level ground and he felt a bump from the tail as the airplane transitioned from the downslope to level ground. The airplane sustained substantial damage to the rudder. The pilot reported 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 identify the taxiway, which resulted in a runway excursion and impact with terrain while turning off the runway at night.
