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 ACFT IS A TWIN-ENGINE CONVERSION OF THE GRUMMAN G-164B. THE PLT WAS ON A LOCAL TEST FLT WITH THE HOPPER FILLED WITH WATER TO SIMULATE FLT CONDITIONS NEAR THE OPERATING GROSS WEIGHT OF THE ACFT. AFTER LIFT-OFF A PARTIAL POWER LOSS WAS EXPERIENCED ON THE #2 ENG. THE PLT EXECUTED A LEFT TURN & BEGAN DUMPING THE LOAD, AT WHICH TIME THE #1 ENG ALSO EXPERIENCE A POWER LOSS. THE ACFT STALLED, BUT THE PLT WAS ABLE TO REGAIN A LEVEL ATTITUDE BEFORE IMPACT. THE ACFT INCORPORATED A COMMON FUEL & FUEL VENT SYSTEM FOR BOTH ENGS, BUT EACH ENG HAD A FUEL SHUTOFF VALVE, FUEL FILTER & FUEL PUMP. EXAMINATION SHOWED A PARTIAL RESTRICTION IN THE FUEL VENT SYSTEM WHEN THE VENT LINE WAS DISCONNECTED. DUE TO IMPACT DAMAGE TO THE FUEL VENT SYSTEM, THE PRECISE NATURE OF THE RESTRICTION THAT WAS FOUND WHEN THE FUEL VENT LINE WAS DISCONNECTED COULD NOT BE DETERMINED. THE PLT LATER RECOMMENDED, HOWEVER, INSTALLATION OF AN AIR PRESSURE OPERATED VANE ON THE FUEL VENT OPENINGS.
