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 reported that after landing and during the turn onto a taxiway intersection, he inadvertently raised the landing gear lever by mistake, rather than the adjacent flap lever. The left landing gear collapsed, which caused the left wing tip to strike the ground. The impact resulted in substantial damage to the left wing. The pilot stated that the accident could have been prevented had he waited until he was clear of the runway, stopped, and identified the flap switch. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation.
NTSB Probable Cause
The pilot inadvertently raised the landing gear lever rather than the adjacent flap level while exiting the runway which resulted in the retraction of the left main landing gear.
