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 THOUGHT THE PROP WAS STUCK, WHEN THE ENGINE DID NOT START WITH THE BATTERY DRIVEN STARTER. HE SAID HE TURNED THE MASTER SWITCH OFF, TURNED THE KEY TO THE OFF POSITION AND PULLED THE MIXTURE & THROTTLE LEVERS ALL THE WAY OUT. HE THEN EXITED THE ACFT TO UNSTICK THE PROP BY A SLIGHT MOVEMENT. HOWEVER, WHEN HE MOVED THE PROP, THE ENG STARTED & THE ACFT MOVED INTO A PARKED AERO COMMANDER. SUBSEQUENT INSPN OF THE MAGNETO SWITCH & MAGNETOS REVEALED NO IRREGULARITIES.
NTSB Probable Cause
THE ENGINE STARTED FOR AN UNDETERMINED REASON, WHEN THE PROP WAS MOVED AFTER THE PILOT EXPERIENCED AN INOPERATIVE STARTER. (MOST PROBABLY, THERE WAS EITHER AN ISOLATED/INTERMITTENT PROBLEM IN THE IGNITION SYSTEM OR THE PILOT DID NOT MOVE THE MAGNETO SWITCH ALL THE WAY TO THE OFF POSITION BEFORE MOVING THE PROPELLER.)
