Incident Overview
A flight instructor and a pilot rated student receiving instruction were operating under instrument flight rules (IFR) in instrument meteorological conditions (IMC). According to the flight instructor, the airplane accumulated light rime ice throughout the flight. After holding at a Very High Frequency Omni-Directional Range (VOR), they completed a VOR approach and executed the missed approach procedure. They set power to climb at 130 knots indicated airspeed and began climbing to 5,000 feet.
Icing Encounter
During the climb, the aircraft encountered freezing rain. The airspeed began to deteriorate, and the degree of ice accumulation increased from light to moderate. The flight instructor reported that all of the airplane's de-ice systems were functioning, yet he was unable to maintain altitude. He determined that landing at the destination airport was not an option and executed a forced landing in an open field.
Landing and Damage
The instructor affirmed that during the landing, the airplane bounced several times before coming to a stop. The airplane sustained substantial damage to the firewall, forward pressure bulkhead, and puncture holes in the airplane skin.
Mechanical Status
The pilot reported that there were no mechanical failures or anomalies prior to or during the flight that would have prevented normal flight operation.
