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.
Belle Chasse, LA
WHEN THE PLT ATTEMPTED TO START THE ENG, IT 'HUNG UP IN THE MIDDLE OF THE COMPRESSION STROKE.' HE STATED THAT AFTER CONFIRMING THAT THE MAGNETOS WERE OFF, HE ATTEMPTED TO 'FREE THE PROPELLER BY HAND.' THE ENG STARTED AS SOON AS THE PROPELLER WAS MOVED. THE NON-PLT PASSENGER IN THE RIGHT FRONT SEAT TRIED TO STOP THE AIRPLANE WITH THE MAGNETO SWITCH. HOWEVER, THE ACFT CONTINUED ABOUT 100 YDS, ROLLED THRU A GUARD RAIL & NOSED DOWN INTO A CANAL. THE MAGNETO SWITCH WAS FOUND IN THE 'BOTH' POSITION, FUEL MIXTURE WAS FULL RICH & THE THROTTLE WAS ADVANCED. A CHECK OF THE MAGNETOS REVEALED NO MALFUNCTION.
