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
CEN11CA637
While returning to the airport after completing an aerial application, the pilot noticed a reduction in engine RPM and a rise in oil temperature. The pilot was unable to maintain altitude and he elected to execute a forced landing to a road. During the forced landing, the left wing contacted a tree and pivoted the airplane into trees. Postaccident examination of the airplane showed both wing spars and the right elevator were bent. Based on his observations during the engine failure and his past engine failure experience, the pilot suspected the main bearing failed within the engine. The engine was not disassembled for further examination and the cause of the engine failure was not determined.
