The Swearingen Merlin II was returning to Thompson after having completed a MEDEVAC flight between Coral Harbour, Northwest Territories, and Churchill, Manitoba. After being cleared for a localizer back course approach to the Thompson Airport, the aircraft descended below the minimum beacon-crossing altitude, struck the Hotel non-directional beacon tower in a wings-level attitude, and crashed. Both crew members were fatally injured, and the flight nurse was seriously injured.
The Board determined that the flight crew lost altitude awareness during the localizer back course approach and allowed the aircraft to descend below a mandatory level-off altitude. Contributing factors to this occurrence were the crew's deviation from a published approach procedure, ineffective in-flight monitoring of the approach, rapidly developing localized fog conditions, and, probably, pilot fatigue.
