Weather Briefing and Approach
During weather briefings, the pilot was advised of icing conditions in the Denver area. While approaching the Denver area, the pilot radioed, "Can you get me down, it's a little bit icy up here." Subsequently, the pilot was asked and given a close turn onto the outer marker.
Missed Approach and Pilot Reports
The aircraft was observed to overfly the airport at about 500 feet AGL. The pilot then acknowledged the missed approach instructions. One minute later, the pilot reported "lots of ice" and stated "I'm stalling out." The pilot reportedly did not like to fly approaches to minimums and set the altitude alerter to an altitude above minimums as a safety margin.
Flight Experience and Aircraft Loading
The pilot had logged 3.5 hours of actual instrument time and 4.1 hours of simulated instrument time, with 3 instrument approaches in the last 6 months. The aircraft's center of gravity was 6 inches aft of the aft CG limit.
