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 PILOT SAID THAT SHORTLY AFTER TAKEOFF AT ABOUT 150 FEET AGL, THE ENGINE BEGAN TO LOSE POWER. UNABLE TO SUSTAIN FLIGHT, AN EMERGENCY LDG WAS ATTEMPTED WHICH RESULTED IN SUBSTANTIAL DAMAGE AND SERIOUS AND MINOR INJURIES TO THE OCCUPANTS. POST ACCIDENT INVESTIGATION REVEALED THE ENGINE'S AIR INDUCTION SYSTEM WAS PLUGGED WITH A FIELD MOUSE NEST, CAUSING ALMOST COMPLETE RESTRICTION OF THE ENGINE'S AIR INDUCTION SYSTEM. THERE WAS NO WAY TO VISUALLY IDENTIFY THE RESTRICTION DURING THE PREFLIGHT DUE TO THE LOCATION OF THE NEST. THE PLT SAID THE PRE-TAKEOFF RUNUP WAS SATISFACTORY, BUT HE THOUGHT THAT DURING THE TAKEOFF ON THE ROUGH PRIVATE STRIP, THE NEST BECAME DISLODGED AND WAS DRAWN FARTHER UP THE INDUCTION SYSTEM AND CARBURETOR CAUSING THE LOSS OF POWER.
NTSB Probable Cause
BLOCKAGE OF THE ENGINE AIR INDUCTION SYSTEM BY A FIELD MOUSE NEST. THE NEST WAS POSITIONED SO THAT IT COULD NOT BE SEEN DURING THE PRE-FLIGHT INSPECTION. IT BECAME DISLODGED DURING THE TAKEOFF ROLL ON THE ROUGH RUNWAY.
