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.

CEN10CA283
The pilot reported that the airspeed indicator was not displaying normal values as the airplane accelerated on the takeoff roll. After identifying the airspeed indicator anomaly, she continued the takeoff roll for an unspecified distance before ultimately deciding to abort the takeoff. The pilot noted that there was an accumulation of dew on the grass runway. During the rejected takeoff, the airplane overran the end of the runway and slid down an embankment before nosing-over in a ravine. Both wings were substantially damaged during the accident. A postaccident inspection revealed that the pilot had not removed the pitot-tube protective cover before departure.
