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
CEN13CA202
The private pilot said she was taxiing her single-engine airplane to the active runway when the engine suddenly went to full power. She did not recall any related engine instrument indications and tried to reduce power by moving the throttle control to its idle position, pulling the mixture control aft, and applying the brakes. During this time, the airplane veered off the taxiway, impacted a snow bank, and nosed over, coming to rest on its back, which resulted in substantial damage to the airframe. Examination of the engine found no mechanical anomalies that would explain the sudden increase in engine power. The pilot had 2,000 feet of taxiway remaining from where the airplane departed the runway.
NTSB Probable Cause
The pilot's failure to maintain airplane control after an unexplained increase in engine power while taxiing.
Full Narrative
The private pilot said she was taxing her single-engine airplane to the active runway when the engine suddenly went to full power. She did not recall any engine instrument indications and tried to reduce power by closing the throttle, pulling the mixture control, and applying the brakes. During this time, the airplane veered off the taxiway, impacted a snow bank, and flipped over on its back causing substantial damage to the airframe. Examination of the engine found no mechanical anomalies that would explain why there was a sudden increase in engine power. The pilot had 2,000 feet of taxiway remaining from where the airplane departed the runway.
