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
WPR09CA388
The pilot reported that he initiated a descending right turn at a slow airspeed to check on livestock. As he added power to arrest the descent rate, he felt the right wing stall, and the airplane impacted terrain. Examination of the airplane by the pilot revealed structural damage to the right wing, fuselage, and empennage. The pilot stated that he had no time to recover due to the low altitude, and reported no mechanical anomalies with the airplane or flight control systems.
NTSB Probable Cause
The pilot’s failure to maintain sufficient airspeed during low altitude maneuvering, which resulted in an inadvertent stall.
