## Discrepancy

DURING PRE-FLIGHT OPERATIONAL CHECKS, THE LEFT ENGINE THROTTLE CABLE STAINLESS STEEL RIBBON CORE PARTED WHERE THE CABLE PASSES THROUGH A CUT-OUT IN THE AILERON BELLCRANK RT MOUNTING BRACKET.  ENGINE CONTROL WAS LOST AND THE MISSION ABORTED.  INVESTIGATION REVEALED THE CABLE INSTALLATION VIOLATED THE 7 INCH MINIMUM BEND RADIUS AT THE POINT OF PARTING.  THE CUT-OUT AREA IN THE BRACKET WAS SUBSEQUENTLY ENLARGED TO RELIEVE THE CABLE BEND.  THE CABLE ASSEMBLY WAS REPLACED AND THE AIRCRAFT RETURNED TO SERVICE.
