Narrative:
The aircraft took off from Milan-Linate (LIN) for a flight to Köln (CGN). Icing conditions existed. Fifteen minutes after takeoff, while climbing through FL147 in IAS hold mode (constant speed set at 133 kts) the aircraft rolled left and right. The plane rolled 41 degrees right, 100 degrees left, 105 degrees right and 135 degrees left. During pull up three anomalous pitch trim movements set the elevator to pitch down, preventing recovery. The ATR crashed nose down into a 700 m high mountain following an uncontrolled descent.
