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 PILOT OF THE CESSNA 175 STATED THAT THE WIND WAS BLOWING DOWN THE RUNWAY AT THIRTY TO FORTY KNOTS, WITH MODERATE TURBULENCE WHEN HE ENTERED THE PATTERN AT THE PRIVATE GRASS AIRSTRIP. HE SELECTED HALF FLAPS AS HE TURNED FINAL APPROACH BUT RAISED THE FLAPS TO THE FULL UP POSITION BECAUSE HE FELT THE WINDS AND TURBULENCE HAD INCREASED. AS THE AIRCRAFT CROSSED THE THRESHOLD THE PILOT REDUCED POWER CAUSING THE STALL WARNING HORN TO ACTIVATE. THE PILOT IMMEDIATELY ADDED POWER, BUT THE AIRCRAFT LANDED HARD BEFORE HE COULD RECOVER.

NTSB Probable Cause
