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.

DURING A TEST FLT OF AN EXPERIMENTAL SEA PLANE, THE PLT RPTD A LOSS OF ENG PWR DURING A TURN IN THE TRAFFIC PATTERN AT CLINTON AIRPORT. THE PLT STATED HE HAD 5 GALLONS OF FUEL ONBOARD AND HAD FLOWN ABOUT 2 TENTHS OF AN HOUR. INSPECTION OF THE FUEL SYSTEM REVEALED THAT DURING TURNS WITH LOW FUEL QUANTITY THE FUEL TANK WOULD BECOME UNPORTED AND THE ENG WOULD QUIT. NO FUEL TANK BAFFLES WERE INSTALLED IN THE TANK TO PREVENT THE FUEL FROM MOVING OUTBOARD FROM THE FUEL LINES. THE PLT STATED THAT THIS PROBLEM WOULD BE CORRECTED WITH THE INSTALLATION OF BAFFLES IN THE TANKS.
