... Abstract An aircraft crashed following the loss of yaw control in full airborne flight. The subsequent discovery of broken shutter bolts in the rear pitch reaction control valve led to an inspection campaign that found bolt failures of a similar nature in valves on several other aircraft. The...

... hydrocarbons) onto metal surfaces. A more recent view of the mechanism of oil/gas field corrosion inhibitors invokes the incorporation of the inhibitor into a thin corrosion-product film. This film then becomes more resistant to the flow of ions and electrons, so the corrosion reaction is slowed ( Ref 4 , 5...
