Executive Summary:The flight crew of the Boeing 727-200 were completing a regularly scheduled passenger flight into Calgary, Alberta. Because of poor weather in Calgary, the flight was delayed for one and a half hours in Salt Lake City, Utah, extending the crew’s scheduled duty day. In Calgary, the crew conducted a flap-30, autopilot-coupled, instrument landing system approach in low visibility to runway 34. The autopilot was disconnected at about 130 feet above ground level. During the landing, the right wing struck the runway. There was damage to the wing tip, the leading edge flaps, the trailing edge flaps, the flap screw-jack, and track fairings of the right wing. The crew was not aware that the wing had struck the runway until the post-flight inspection was completed on the Calgary ramp. No one was injured in the accident.
