The air ambulance Beechcraft A100 King Air, Voyageur 796, with two flight crew members and two paramedics on board, departed Timmins for Chapleau, Ontario on an instrument flight rules (IFR) flight. There, a seriously injured person was to be boarded and flown to Sault Ste. Marie, Ontario. The aircraft proceeded from Timmins en route at 12,000 feet, and, on arrival at Chapleau, the aircraft overflew the airport at low altitude and crashed 1.5 miles southwest of the airport. The four occupants were fatally injured, and the aircraft was destroyed by the impact and post-impact fire. Causes: “The flight crew descended below the minimum applicable IFR altitude while approaching the Chapleau NDB. It could not be determined why the crew allowed the aircraft to descend, in controlled flight, into the ground.”
