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.

GAA17CA039
The flight instructor in the weight shift aircraft, which was equipped with a floor mounted, foot operated throttle, reported that upon startup, the pilot receiving instruction inadvertently applied full throttle while putting his right foot on the pedal power control unit. Subsequently, the weight shift aircraft started to move towards a parked jet, so the flight instructor turned the aircraft sharply and the aircraft tipped onto its side. The weight shift aircraft sustained substantial damage to both wings. The flight instructor reported that there were no pre impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation.
NTSB Probable Cause
The pilot receiving instruction's inadvertent application of throttle during the engine start, which led to an inadvertent acceleration and a roll-over.
