An aircraft on a VFR/IFR flight plan accumulated ice in cruise, lost power to one engine, and conducted a forced landing in a wooded area under IFR conditions.

Incident Overview

The aircraft was in cruise flight under a VFR/IFR flight plan when ice began to accumulate on the airframe. The pilot was unable to maintain altitude, and power was reportedly lost to one engine. Subsequently, a forced landing was conducted, with the aircraft coming to rest in a wooded area.

Weather and Environmental Conditions

At the time of the incident, the weather was IFR with heavy snow. The temperature and dew point were both measured at 21 degrees Fahrenheit. Prior to the flight, the pilot and an ATP-rated passenger had requested and received several weather reports concerning both en route and destination conditions. These reports had forecast the conditions that were eventually encountered.

Examination and Pilot Actions

Both engines were examined after the forced landing, and no mechanical malfunctions were found. The pilot reported that carburetor heat was applied after the loss of power occurred in one engine. The source provides no further details on the aircraft type, registration, or other specifics.

Summary

The aircraft encountered ice accumulation and subsequent engine power loss, leading to a forced landing in a wooded area. The source does not state a probable cause.
