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 RIGHT ENGINE LOST POWER DURING THE INITIAL CLIMB AFTER LIFT-OFF. A WITNESS HEARD A NOISE & OBSERVED FLAMES COMING FROM THE RIGHT ENGINE COWLING AS THE AIRPLANE CLIMBED. THE AIRPLANE ENTERED A TURN AFTER CLIMBING ABOUT 200 FT, DESCENDED THROUGH A SMALL GROVE OF TREES, CRASHED IN A PASTURE, AND BURNED. DURING TAKEOFF, THE PLANE'S GROSS WEIGHT WAS ABOUT 11,050 LBS & THE CG WAS BEHIND THE AFT LIMIT. ITS MAXIMUM CERTIFIED WEIGHT LIMIT WAS 9700 LBS. THE PILOT WAS AWARE OF A GROSS WEIGHT PROBLEM BEFORE TAKEOFF. AN EXAM REVEALED EVIDENCE THAT THE LEFT ENGINE PROPELLER WAS IN THE FEATHERED POSITION & THE RIGHT PROPELLER WAS NOT FEATHERED AT IMPACT. A CHECK OF THE RIGHT ENGINE DISCLOSED THAT THE NUMBER 3 CYLINDER INTAKE VALVE HAD FAILED FROM FATIGUE.
NTSB Probable Cause
THE PILOT'S IMPROPER EMERGENCY PROCEDURE BY SHUTTING DOWN THE WRONG ENGINE, WHICH RESULTED IN A FORCED LANDING. FACTORS RELATED TO THE ACCIDENT WERE: FAILURE OF THE NUMBER THREE INTAKE VALVE IN THE RIGHT ENGINE DUE TO FATIGUE, AND TREES IN THE EMERGENCY LANDING AREA.
