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.

AFTER LOWERING COLLECTIVE CONTROL TO PERFORM A SIMULATED AUTOROTATIVE LANDING WITH FULL THROTTLE APPLIED, THE CFI OBSERVED THAT THE ENG RPM DROPPED TO ZERO & THE MANIFOLD PRESSURE GAUGE INDICATED 30 INCHES. DURING THE EMERGENCY DESCENT AT AN ALTITUDE OF 100 FEET, HE OBSERVED POWER LINES AHEAD. HE PULLED COLLECTIVE CONTROL & CLEARED THE LINES BUT THE HELICOPTER LANDED HARD RT SKID LOW. THE RT SKID BROKE & THE HELICOPTER ROLLED ON ITS RIGHT SIDE & CAME TO REST. THE HELICOPTER WAS RECOVERED & TAKEN TO THE OPERATOR'S FACILITY FOR EXAM. THE FUEL SYS WAS CHECKED FOR CONTAMINANTS; NONE WERE FOUND. FUEL QUANTITY WAS SUFFICIENT TO SUSTAIN ENG OPERATION. THE ENG WAS STARTED & FOUND TO OPERATE NORMALLY. NO DETERMINATION COULD BE MADE AS TO THE REASON FOR THE REPORTED LOSS OF ENG POWER.
NTSB Probable Cause
IMPROPER COLLECTIVE AND CYCLIC CONTROL INPUT BY THE PILOT-IN-COMMAND DURING THE FORCED LANDING FOLLOWING TOTAL LOSS OF ENGINE POWER DUE TO UNDETERMINED REASONS.
