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
WPR23LA151
The pilot of the tailwheel-equipped airplane reported that, while flying low to observe the unusual water flows from mountains, he noted abnormal engine behavior. He elected to perform a precautionary landing on flat terrain due to nearby rising terrain. Upon touchdown, the airplane experienced a slight ballooning effect, leading the pilot to apply maximum braking upon touchdown. The tires grabbed harder than expected due to soft terrain and the airplane nosed over and came to rest inverted, which resulted in substantial damage to the fuselage. A postaccident engine test run by the pilot revealed no anomalies or an explanation for the abnormal engine behavior.
NTSB Probable Cause
The pilot’s braking technique during an off airport precautionary landing on unforeseen soft terrain, which resulted in a nose over.
