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.

AFTER DESCENDING FM 2500 TO 2000 FT, THE PLT REALIZED THE ENG HAD LOST PWR, WHEN IT DID NOT RESPOND TO THROTTLE MOVEMENTFOR LEVEL OFF. HE MOVED THE CARBURETOR HEAT TO THE 'ON' POSITION, BUT WAS UNABLE TO RESTART THE ENG. SUBSEQUENTLY, HE MADE AN EMERGENCY LANDING IN A PLOWED FIELD & THE LANDING GEAR COLLAPSED ON SOFT TERRAIN. THE CARBURETOR WAS DAMAGED DURING THE OCCURRENCE. AFTER IT WAS REPLACED, THE ENG WOULD OPERATE. AN EXAM OF THE DAMAGED CARBURETOR REVEALED ONLY NORMAL WEAR. THE TEMP & DEW POINT WERE 64 & 44 DEG, RESPECTIVELY. ACCORDING TO CARBURETOR ICING CHARTS, CONDITIONS WERE CONDUCIVE TO CARBURETOR ICE.
