Détails:
The Cessna departed Mathis Field (SJT) for a proficiency check flight. The airplane executed a few instrument approaches at Mathis Field and proceeded to Ducote Airpark. While on final approach at 100-200 feet the engine surged. Subsequently, the airplane's wings began to bank left and right.
The airplane entered a descent rate of 1,300 feet/minute (fpm) about 1,100 feet above the ground. This rate of descent was associated with a decrease in airspeed from 130 knots to 92 knots over a span of 30 seconds. The airplane's rate of descent leveled off at the 1,300-fpm rate for 45 seconds before
increasing to a 2,000 fpm descent rate. The true airspeed fluctuated between a low of 88 knots to 102 knots during the last 45 seconds of flight.
The Caravan contacted power lines and trees, and impacted the ground. Two of the witnesses reported that they observed between 1/4 and 1-inch of ice on the various protected and unprotected surfaces of the aircraft.

Probable Cause:

PROBABLE CAUSE: "The flight crew's failure to cycle the deice boots prior to conducting a simulated forced landing and their failure to maintain adequate airspeed during the maneuver, which resulted in an inadvertent stall and subsequent loss of control. A contributing factor was the ice accumulation on the leading edges of the airfoils."
