Probable cause

The pilot's failure to maintain directional control of the airplane after becoming spatially disoriented. Factors related to the accident were: darkness, low overcast cloud condition, the pilot's decision to continue VFR flight into instrument meteorological conditions (IMC), which resulted in a near collision with another aircraft, his self induced pressure and diversion of attention, while coping with the situation that he had encountered.
