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 FLT WAS FOR THE PURPOSE OF X-COUNTRY TRAINING. THE FLT INSTRUCTOR (CFI) CLOSED THE THROTTLE AT AN ALT OF ABT 900' AGL TO SIMULATE AN ENG FAILURE. DRG A SUBSEQUENT AUTOROTATION, ENG RPM WAS NOT MAINTD AT 2500 AS RCMDD BY THE PLT'S OPERG HANDBOOK (POH). THE STUDENT ALLOWED THE ROTOR RPM TO DETERIORATE DRG AN ATMTD PWR ON RECOVERY AT ABT 700' AGL AS HE DID NOT REALIZE THE ENG HAD STOPPED RUNNING. THE CFI ATMTD TO RESTART THE ENG AFTER TAKING CTL OF THE HELICOPTER AT ABT 700' AGL. THE STUDENT RPRTD THE ROTOR RPM REMAINED LOW DRG THE DSCNT. SUBSEQUENTLY, THE HELICOPTER IMPACTED IN A LARGE FLD. THE STUDENT STATED THAT THE HELICOPTER FELT AS IF IT JUST DROPPED THE LAST FEW FT OF THE AUTOROTATION. NO REASON WAS VERIFIED FOR THE LOSS OF ENG PWR. THE POH STATED THAT RPM SHOULD HAVE BEEN MAINTD DRG PRACTICE AUTOROTATIONS & THAT ENG RESTARTS SHOULD NOT BE ATMTD BELOW 2000' AGL.
NTSB Probable Cause
LOSS OF ENGINE POWER FOR AN UNDETERMINED REASON, AND FAILURE OF THE INSTRUCTOR PILOT (CFI) TO FOLLOW PROCEDURES AND MAINTAIN ROTOR RPM.
