N55259

Piper PA-28-140

Analysis

The pilot said that engine power was lost during initial climb. He conducted a forced landing off the airport and the airplane impacted a fence. According to the Icing Probability Chart, the conditions favorable to the formation of induction system icing existed based on the temperature and dew point at the two nearest reporting stations. The pilot said that he 'tried' carburetor heat after the loss of power; however, the airplane touched down prior to engine power being restored.

Factual Information

On December 9, 1997, at 1200 central time, a Piper PA-28-140, N55259, sustained substantial damage during a forced landing after departing a private airstrip. The pilot reported no injuries.

The flight was originating at the time of the accident. Bismarck Municipal Airport, 40 miles to the west of the accident site was reporting instrument meteorological conditions in the form of a ceiling of 800 feet, five minutes prior to the accident. The temperature was 26 degrees (F),and the dew point was 23 degrees (F). Jamestown Municipal Airport 52 miles to the east of the accident site was reporting instrument meteorological conditions in the form of visibility one and one-half miles in light snow and fog, 12 minutes prior to the accident. The temperature was 28 degrees (F) and the dew point was 23 degrees (F). The pilot reported conditions at the accident site as clear with unrestricted visibility. The pilot said that after the initial loss of power and he initiated a forced landing, he switched tanks and "tried" the carburetor heat, but engine power was not restored prior to the airplane touching down and impacting a fence.. An Icing Probability chart from a Federal Aviation Administration Advisory Circular is attached to this report. The temperatures and dew points from the above reporting stations indicate conditions favorable to formation of induction system icing.

Probable Cause and Findings

The pilot's improper use of carburetor heat. Factors were carburetor icing conditions and a fence.
