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.

MOMENTARILY AFTER LIFTING OFF, THE PLT HEARD A PRONOUNCED DECREASE IN ENG NOISE & NOTED THAT THE TACHOMETER INDICATION HAD DROPPED TO 1950 RPM. HE ELECTED TO ABORT, BUT WAS UNABLE TO STOP ON THE REMAINING RWY. AFTER DEPARTING THE RWY, THE ACFT HIT AN OBJECT & RAN INTO A RAVINE BEFORE COMING TO REST. AN EXAM OF THE MARVELL SHEBLER CARBURETOR, MODEL MA4SPA, REVEALED A LEAK IN THE GASKET, PN 16-A48. THERE WAS EVIDENCE THAT THIS WOULD RESULT IN PARTIAL FUEL STARVATION.
