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 RPRTD THAT WHEN THE ACFT WAS AT APRX 150' TO 200' AGL ON FINAL APCH, THE ENG LOST PWR & WOULD NOT RESTART. UNABLE TO RCH THE RWY, HE LNDD ABOUT 50' SHORT ON SOFT TRRN, WHERE THE GEAR COLLAPSED & THE ACFT WAS DMGD. ONLY ABOUT 12 OUNCES OF FUEL WAS REMAINING IN THE LEFT TANK, BUT 13 GAL WAS FND IN THE RGT TANK. DRG POST-ACDNT CHECKS, 3 GAL OF FUEL WAS ADDED TO THE LEFT TANK. HOWEVER, THE ENG WOULD NOT START IRREGARDLESS OF THE FUEL SELECTOR PSN. WHEN AN INDEPENDENT FUEL SOURCE WAS CONNECTED TO THE INLET FUEL LINE, THE ENG STARTED & OPERATED NORMALLY. HOWEVER, WHEN THE ENG WAS RECONNECTED TO THE ACFT FUEL SYS, IT RAN ONLY BRIEFLY & WOULD NOT RESTART, EVEN THOUGH FUEL IN THE TANKS EXCEEDED THE UNUSABLE LVL OF 1.3 GAL/TANK. A TEST OF THE BOOST PUMP SHOWED THAT AT 23 PSI, ITS FLOW RATE WAS 9 GPH; THE PUMP SPECIFICATION WAS FOR 35 GPH AT 23 PSI.
