Incident at Buffalo Narrows, Saskatchewan


1997-03-18: While landing on a frozen ice strip the left ski of a Cessna 140 broke, causing the aircraft to veer left and the prop to strike the ice. The damage was limited to the left ski, propeller and a crack in the windshield. It was reported that the failure of the federal 1500 ski, occurred in the pedestal area where it joins the base of the ski. The initiating failure is believed to be caused by dissimilar metal corrosion between the aluminum rivets and the steel pedestal support structure. The skis were installed by the pilot/operator at the beginning of the ski season, approximately 25 hours prior to the failure.
