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.

THE CERTIFIED FLIGHT INSTRUCTOR STATED THAT HIS INTENTIONS FOR THIS FLIGHT WERE TO SIMULATE AN ENGINE POWER LOSS DURING THE EARLY STAGES OF THE TAKEOFF ROLL AND HAVE THE STUDENT PERFORM A REJECTED TAKEOFF PROCEDURE. ACCORDING TO THE C.F.I., AT APPROXIMATELY 48 KNOTS HE REDUCED POWER ON THE LEFT ENGINE BY CUTTING OFF FUEL FLOW WITH THE MIXTURE CONTROL BUT THE STUDENT'S SLOW REACTION TO ABORT THE TAKEOFF, AND THE GUSTY CROSSWIND CONDITIONS CAUSED THE AIRCRAFT TO VEER OUT OF CONTROL, BEYOND CORRECTIVE ACTION. POST-ACCIDENT CALCULATIONS REVEAL THAT THE RUNWAY IN USE HAD A HEADWIND COMPONENT OF 17 KNOTS, A CROSSWIND COMPONENT OF 11 KNOTS, AND A DENSITY ALTITUDE OF 3,000 FEET ACTING ON NORMALLY ASPIRATED ENGINES.
