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
CHI07CA109

The airplane sustained substantial damage during an inadvertent wheels-up landing. The pilot stated that he entered a left downwind for runway 32 (2,803 feet by 75 feet, asphalt) at the intended destination airport. He reported that he lowered the landing gear and completed the before landing checklist. He noted: "All indications showed that [the landing] gear was down." He reported that during the landing flare, he "felt and heard metal grinding on the runway," and immediately executed a go-around. During the go-around, the airplane exhibited a right rolling tendency. Although the pilot was able to maintain control, he was unable to avoid striking trees during the climb out. He subsequently noticed that the flaps were still down and raised them. The pilot returned to the airport for another landing attempt. He stated: "I lined up for a short final with my gear showing down and locked, flaps set to approach setting and power at almost [maximum]. I was able to land the aircraft and taxi to the ramp without further incident, where I parked and shut down." During the post accident inspection, the landing gear was observed in the down and locked position. Visual inspection of the landing gear did not reveal any anomalies. Three green landing gear position indicator lights were illuminated when the airplane was powered up during the inspection.

NTSB Probable Cause

The pilot's inadvertent failure to lower the landing gear.
