Narrative:The Viking, named "Shangani", disintegrated in flight after encountering a sudden gust of wind. It appeared that the type of grease used when fitting press fit bolts to the booms had caused corrosion nodes, thus weakening the lower starboard boom at the outboard bolt hole. The gust of wind caused a fracture of this boom outboard of Station 141, followed by the complete disintegration of the aircraft.
