What happened
During the flight, the crew encountered significant ice buildup on the cockpit windscreen. In an effort to restore visibility, the crew utilized a scraper to manually remove the accumulation of ice. During this process, the aircraft experienced a noticeable reduction in airspeed.
In an attempt to recover the lost speed and regain stable flight, the captain implemented corrective maneuvers. However, these inputs were improper for the flight conditions, resulting in an aerodynamic stall. The aircraft subsequently crashed, leading to the total destruction of the airframe. There were three injuries reported among the occupants, with no fatalities occurring during the accident.
Findings
Investigations into the event indicate that the primary factor was the improperly executed recovery maneuvers following the loss of airspeed caused by the ice removal process.
