The NTSB released preliminary information last month after a Citation II hit terrain during a circling approach to Dillon Airport in southwest Montana, killing both people aboard. According to the report, the ATP-rated owner-pilot was operating the aircraft, which was registered to Hamilton Ranches of Itasca, Ill. The lowest ceiling at the time of the accident was 3,900 feet overcast, and visibility was reported as 10 miles. The local metar also reported a scattered layer at 1,700 feet. The first point of contact was a 27-foot ground scar found less than a quarter of a mile from the runway.
