Narrative:The Kenn Borek Air Beechcraft 100, operating as flight KBA103, was on an instrument flight rules flight from the Edmonton City Centre Airport to Kirby Lake, Alberta. At approximately 11:14, during the approach to runway 08 at the Kirby Lake Airport, the aircraft struck the ground, 174 feet short of the threshold. The aircraft bounced and came to rest off the edge of the runway. There were 2 flight crew members and 8 passengers on board. The captain sustained fatal injuries. Four occupants, including the co-pilot, sustained serious injuries. The 5 remaining passengers received minor injuries. The aircraft was substantially damaged. A small, post impact, electrical fire in the cockpit was extinguished by survivors and first responders. The emergency locator transmitter was activated on impact.
Probable Cause:
FINDINGS AS TO CAUSES AND CONTRIBUTING FACTORS:
1. The conduct of the flight crew members during the instrument approach prevented them from effectively monitoring the performance of the aircraft.
2. During the descent below the minimum descent altitude, the airspeed reduced to a point where the aircraft experienced an aerodynamic stall and loss of control. There was insufficient altitude to effect recovery prior to ground impact.
3. For unknown reasons, the stall warning horn did not activate; this may have provided the crew with an opportunity to avoid the impending stall.
