Pilot Encounters Icing, Loses Control During Missed Approach (N7724N)

Aurora, United States of AmericaLanding (descent or approach)

On November 22, 1983, a Cessna 414 Chancellor (registration N7724N) operated by William Geary was involved in an aviation accident near Aurora, United States of America during landing or approach. 2 people were killed. Investigators recorded the probable cause as: Improper IFR procedure by the pilot-in-command, failure to attain decision height, and ice accumulation on the wing. This summary draws on records from the Bureau of Aircraft Accidents Archives (B3A).

A pilot flying into known icing conditions reported ice accumulation and stall, then lost control during a missed approach. The aircraft had an aft CG limit exceeded and the pilot had limited recent instrument experience.

Weather Briefing and Approach

During preflight weather briefings, the pilot was advised of icing conditions in the Denver area. While approaching Denver, the pilot radioed, "Can you get me down, it's a little bit icy up here." Air traffic control subsequently asked the pilot and gave a close turn onto the outer marker. The aircraft was observed to overfly the airport at about 500 feet above ground level.

Missed Approach and Loss of Control

The pilot acknowledged the missed approach instructions. One minute later, the pilot reported "lots of ice" and "I'm stalling out." The aircraft then lost control during the missed approach phase.

Pilot Background and Aircraft Loading

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. The pilot had logged 3.5 hours of actual instrument time and 4.1 hours of simulated instrument time, along with 3 instrument approaches in the preceding six months. The aircraft's center of gravity was 6 inches aft of the aft center of gravity limit.

Official Findings

The investigation identified three occurrences: an in-flight encounter with weather, a loss of control during missed approach, and an in-flight collision with terrain. Findings included intentional flight into known icing conditions, improper IFR procedures, decision height not attained, underconfidence in personal ability, lack of recent instrument time, and ice accumulation on the wing. Contributing factors were dark night, snow, low ceiling, and the pilot's improper execution of the missed approach.

Probable cause

Improper IFR procedure by the pilot-in-command, failure to attain decision height, and ice accumulation on the wing.
