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.

NTSB Number
CHI08CA060
The pilot encountered a partial loss of engine power during flight. The use of carburetor heat did not regain the lost power. The pilot performed a precautionary landing to a grass landing strip he had landed at before. The airplane nosed over in the snow upon landing. No pre-impact anomalies were detected. The local temperature and dew point was -2 degrees C and -9 degrees C respectively. The owner's recommendation was to "replace the metal tube with scat tube on carb heat side."
NTSB Probable Cause
The partial loss of engine power for undetermined reasons during cruise and the unsuitable terrain encountered during the precautionary landing. A factor was the snow-covered ground.
