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.

ABOUT 10 MINUTES AFTER TAKEOFF, AT AN ALTITUDE OF 1,400 FEET MSL, THE AIRPLANE'S ENGINE LOST TOTAL POWER. THE PILOT COULD NOT RESTART THE ENGINE SO HE MADE A FORCED LANDING IN A RESIDENTIAL AREA. DUE TO THE CONGESTED AREA, THE PILOT COULD NOT MANEUVER THE AIRPLANE. TO AVOID HITTING A HOME OR POWERLINE, THE PILOT STALLED THE AIRPLANE AT ABOUT 200 FEET ABOVE THE GROUND. THE AIRPLANE FELL 200 FEET ONTO A ROAD. EXAMINATION OF THE WRECKAGE DISCLOSED THAT THE LEFT AND RIGHT FUEL VENT LINES WERE TOTALLY BLOCKED BY INSECT NESTS, WHICH TERMINATED THE FLOW OF FUEL TO THE ENGINE. THE BLOCKAGES WERE FOUND IN THE FUEL VENT LINES AT THE WING ROOT.
NTSB Probable Cause
THE BLOCKAGE OF THE RIGHT AND LEFT FUEL VENT LINE WHICH PREVENTED THE FLOW OF FUEL TO THE ENGINE CAUSING TOTAL POWER LOSS.
