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.

According to the pilot, he was departing runway 16 on an instrument flight rules flight plan. After traveling down approximately two-thirds of the 4,002 foot runway, he elected to abort the takeoff after he felt the airplane was not able to climb and continue to accelerate. During the aborted takeoff, the airplane departed the runway surface and entered the grass overrun area which was covered with wet dew from the morning environmental conditions. The pilot attempted to stop the airplane; however, the airplane skidded and impacted a fence. The airplane sustained substantial damage to the right main wing spar and fuselage. The examination of the airplane revealed no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operations.
NTSB Probable Cause
The airplane's inability to takeoff for reasons that could not be determined because postaccident examination of the airplane revealed no anomalies. The aborted takeoff resulted in a runway overrun and impact with a fence.
