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
ANC22LA034
The pilot reported that, while on final approach to landing at a private airstrip, he was slow to correct for a slower-than-normal airspeed. Subsequently, the airplane entered an aerodynamic stall, and descended into a swampy area short of the runway. The airplane sustained substantial damage to the wings. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot's failure to maintain adequate airspeed during final approach which resulted in the airplane exceeding its critical angle of attack and a subsequent aerodynamic stall at too low of an altitude to recover.
