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 INSTRUCTOR RETARDED THE THROTTLE AND ASKED THE PILOT TO DEMONSTRATE A SIMULATED FORCED LANDING. AFTER DEMONSTRATING THE PROCEDURE, THE PILOT APPLIED FULL THROTTLE BUT THE ENGINE DID NOT RESPOND. THE INSTRUCTOR ASSUMED CONTROL OF THE AIRPLANE, LANDED ON UNEVEN TERRAIN, AND THE AIRPLANE OVERTURNED. THE ENGINE WAS LATER TESTED AND FUNCTIONED NORMALLY. THE INSTRUCTOR AND PILOT LATER SAID CARBURETOR HEAT HAD NOT APPLIED PRIOR TO THE POWER REDUCTION, AND CARBURETOR ICE CAUSED THE POWER LOSS. THE ENGINE WAS LATER FUNCTIONALLY TESTED BY THE FAA COORDINATOR. IT RAN NORMALLY.
NTSB Probable Cause
A POWER LOSS DUE TO CARBURETOR ICE RESULTING FROM THE FLIGHT INSTRUCTORS FAILURE TO USE CORRECT ENGINE MANAGEMENT PROCEDURES. A FACTOR WAS THE ROUGH TERRAIN IN WHICH THE FORCED LANDING WAS PERFORMED.
