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.

POWER WAS REDUCED AT 1,000-1,200 FT AGL FOR A SIMULATED ENGINE FAILURE. POWER WAS THEN ADDED FOR RECOVERY AT 150 FT AGL BUT THE ENGINE DID NOT RESPOND. THE AIRPLANE NOSED OVER IN A FRESHLY PLOWED FIELD. THE TEMP/DEW POINT WAS 45/32. THE CFI STATED THAT HE THOUGHT THE OUTSIDE AIR TEMP AT THE TIME WAS 55-60 DEG AND THAT THE USE OF CARB HEAT WAS NOT WARRANTED FOR THE MANEUVER.
NTSB Probable Cause
THE FLIGHT INSTRUCTOR'S FAILURE TO USE CARBURETOR HEAT DURING A SIMULATED ENGINE FAILURE. THE ROUGH TERRAIN AND WEATHER CONDITIONS CONDUCIVE TO CARBURETOR ICING WERE CONTRIBUTING FACTORS.
