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
CEN13CA528
During the takeoff roll, a hawk struck the airplane's windscreen and then struck the vertical stabilizer and rudder. The airplane veered to the right, exited the runway and nosed over. The airplane sustained substantial damage to the vertical stabilizer and rudder. A postaccident examination revealed that the hawk had lodged between the vertical stabilizer and rudder which interfered with the flight controls and deflected the rudder to the right. There were no preaccident mechanical malfunctions or failures with the airplane or engine that would have precluded normal operation.
NTSB Probable Cause
The collision with a hawk during the takeoff roll, which resulted in a loss of directional control, runway excursion, and subsequent noseover.
