Accident Sequence
Approximately 15 minutes after departure from Milan-Linate Airport, while climbing to 14,700 feet, the flight crew encountered severe icing conditions. Maintaining a constant speed of 133 knots, the aircraft began to experience uncontrolled roll oscillations. It first rolled to the right to an angle of 41°, then to the left to 100°, followed by a right roll to 105°, and finally a left roll to 135°. The aircraft became uncontrollable, nosed down, and crashed into the slope of Mount Crezzo, located about 50 kilometers north of Linate Airport. The impact totally destroyed the aircraft and all 37 occupants were killed.
Investigation Findings
The official investigation determined the probable cause of the accident. The primary factor was a loss of longitudinal controllability attributed to the severe icing conditions encountered during the climb. Additionally, the inexperience of the crew was considered a contributing factor to the chain of events leading to the loss of control.
