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 PLT REPORTED THAT THE ENGINE LOST 50% POWER JUST AFTER TAKEOFF. THE PLT APPLIED FULL CARB HEAT FOR ABOUT 3 MINUTES, THEN MOVED THE CARB HEAT CONTROL TO THE HALF-ON POSITION. THE AIRPLANE REMAINED AIRBORNE FOR SEVERAL MORE MINUTES AS HE ATTEMPTED TO LOCATE A SUITABLE LDG AREA. THE PLT OBSERVED THAT THE ENGINE MANIFOLD PRESSURE WOULD NOT EXCEED 23 INCHES EVEN WITH FULL THROTTLE. THE ENGINE EVENTUALLY LOST ALL POWER AND A FORCED LDG WAS MADE IN A SOFT FIELD. THE AIRPLANE NOSED OVER DURING THE LDG. AFTER THE AIRPLANE WAS RECOVERED FROM THE CRASH SITE, AN ATTEMPT WAS MADE TO RUN THE ENGINE; IT RAN ROUGH WHEN FIRST STARTED, THEN SMOOTHED OUT AND DEVELOPED PWR. THE ENGINE DEVELOPED NEAR-MAXIMUM RATED RPM, AND NO PROBLEMS WERE NOTED. EXAMINATION OF CARBURETOR ICING PROBABILITY CURVE REVEALED THAT REPORTED WX CONDITIONS WERE FAVORABLE FOR LIGHT ICING AT GLIDE OR CRUISE PWR.

NTSB Probable Cause

THE PILOT'S IMPROPER USE OF THE CARBURETOR HEAT CONTROL WHICH RESULTED IN A LOSS OF ENGINE POWER. CONTRIBUTING TO THE ACCIDENT WERE CONDITIONS CONDUCIVE TO CARBURETOR ICE.
