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.

The pilot stated that he and the passenger were nearing the conclusion of a local flight when the engine began to "sputter and run rough." The engine momentarily ran smooth before it began to run rough a second time, followed by a total loss of power. The pilot maneuvered the airplane for a forced landing, and stated that engine power was restored just prior to impact with trees and terrain. The airplane came to rest upright, and sustained substantial damage to both wings and the empennage. During a postaccident wreckage examination, a 1-quart fuel sample was drained from the airplane, and about half of the sample was water. The pilot stated that prior to the accident flight, he had mistakenly fueled the airplane from a container of contaminated fuel.
NTSB Probable Cause
A loss of engine power while maneuvering due to water contamination in the fuel.
