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.

CEN10CA060
The pilot reported that the airplane's engine quit when the airplane was about 150 feet above ground level after takeoff. He stated that after about 3 seconds the engine restarted and ran for another 6 to 7 seconds before quitting again. The pilot elected not to land on a busy highway and selected a small field to attempt a forced landing. He realized he would not be able to make the field and elected to stall the airplane into trees. Subsequent examination of the engine confirmed engine crankshaft and valve train continuity. Each cylinder produced "thumb" compression and the magnetos produced spark at all leads when the engine was rotated by hand. Fuel was found within the fuel tank and fuel lines leading to the engine. No anomalies were found that would explain the reported loss of engine power.
