Circumstances:
The twin engine airplane departed Fort McMurray Airport at 1706LT on a one-hour flight to Edmonton, carrying two pilots. The first officer was occupying the left seat and at the controls. The flight was cleared to descend to 5,500 feet for a visual approach to runway 30 at Edmonton Municipal Airport. When below cloud at 8,000 feet, about 40 miles north of the airport, the first officer saw the lights of Fort Saskatchewan ahead and to the left, and the Municipal Airport ahead and to the right. He has no recollection of the subsequent events of the flight. The aircraft was observed to be on a stable but lower than normal final approach. It then suddenly banked sharply to the left and dropped at a steep angle towards the Royal Alexandra Hospital. The aircraft struck then penetrated the side of the mechanical penthouse and settled on to the wider roof the the six-storey hospital. The unoccupied penthouse contained heating, ventilating and electrical equipment. The airplane was destroyed and both crew members were seriously injured. The following day, the pilot died from injuries sustained.
Probable cause:
The aircraft experienced a reduction or loss of engine power to one or both engines for undetermined reasons. The aircraft departed from controlled flight on final approach.
