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 ACFT HAD BEEN AIRBORNE FOR ABOUT ONE HOUR WHEN THE ENG LOST POWER. THE PLT ATTEMPTED A FORCED LANDING AND PICKED AN OPEN AREA. STRONG SURFACE WINDS RESULTED IN AN UNDERSHOOT OF THE SELECTED AREA AND WHEN HE TRIED TO STRETCH THE GLIDE THE ACFT STALLED AND LANDED HARD. THE PLT SAID THE ENG IS FROM A GROUND POWER UNIT AND HAS ONLY ONE MAGNETO. HE SAID THE MAGNETO COIL FAILED.
NTSB Probable Cause
THE FAILURE TO THE MAGNETO. THE SELECTION OF A POWERPLANT WITH A SINGLE MAGNETO SYSTEM WAS AN IMPROPER CHOICE AND DIRECTLY CONTRIBUTED TO THE CAUSE. THE PILOT'S MISJUDGEMENT OF THE WIND FOR THE APPROACH TO A FORCED LANDING RESULTED IN AN IMPROPER GROUND CONTACT.
