What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
This office has concluded an investigation of an incident that occurred during a training flight at the Denton municipal airport (kdto) on February 24, 2012. The instructor and student pilot failed to follow the landing checklist, which resulted in the gear up landing. A post incident inspection of the aircraft's landing gear system did not show any failure of the gear components. Contributing to the incident was the crew's diverted attention while following ATCT instructions for a short approach because of the traffic flow. This factor and the sun shining on the gear indicator lights caused the instructor to think the lights were illuminated. The instructor did not take the time to shield the three green lights from the sun to verify the gear was down.
