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.

According to the pilot, while flying over a river at an altitude of about 100 feet above water and ground level, at 250 knots, the airplane impacted unmarked power line wires that spanned the river. The power line wires are clearly identified on the Visual Flight Rules Sectional Aeronautical Chart. The pilot immediately established a climb and returned to the airport without further incident. The airplane sustained substantial damage to the nose, left wing, and vertical stabilizer. The pilot reported that there were no pre-impact mechanical failures or malfunctions that would have precluded normal operation.
NTSB Probable Cause
The pilot's inadequate preflight planning and subsequent failure to remain clear of power line wires while maneuvering at low altitude.
