Flew into the sea, while descending too low during an instrument approach to runway 22L.

Probable Cause:

The probable cause of this accident was loss of control of the aircraft at the moment where the aircraft was about to intercept the ILS glideslope to runway 22L at Copenhagen airport, Kastrup.
Although it has not been possible to establish the cause of the loss of control, it is most likely to believe that the aircraft in the landing configuration was affected by a deterioration of the airflow over the tailplane to such a degree that longitudinal stability was lost.
