Circumstances:

The captain decided to continue and started the approach when the airplane struck a tree and crashed 5 km from the airfield. Both pilots and six passengers were killed while three others were injured.
Probable cause:
The probable cause of the accident was that the pilot persisted with such determination or confidence in his attempts to reach his destination in the face of deteriorating weather conditions, that he did not ensure he could safely discontinue the approach at any time and still maintain visual reference to the significant terrain.
