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 during the approach, the left main landing gear did not extend. The pilot attempted to cycle the landing gear and utilize the alternate landing gear extension system; however, the left main landing gear remained in the stowed position. The pilot chose to perform a gear up landing, which resulted in substantial damage to both engine mounts. The pilot reported that a postaccident examination revealed that the landing gear tires were incorrect part number and oversized by about 1 inch, and maintenance personnel changed the tires two days before the accident. Due to the oversized tire, the left main landing gear became wedged in the wheel well, which prevented the landing gear from extending.
NTSB Probable Cause
Maintenance personnel's installation of an oversized tire, which prevented the left main landing gear from extending resulting in a precautionary gear up landing.
