## Discrepancy

THROTTLE KNOB DISCONNECTED DUE TO CABLE BREAKING INSIDE LINKAGE ASSEMBLY.  SUSPECTED FORCEFUL PUSHING IN OF THROTTLE KNOB AGAINST FIREWALL, OVER TIME, CAUSED CABLE TO BULGE INSIDE PLASTIC SHEATH, EVENTUALLY CAUSING INDIVIDUAL CABLE STRANDS TO BREAK THROUGH.  STRANDS THEN SEPARATED INDIVIDUALLY.  POTENTIAL PROBLEM FOR HIGH TIME THROTTLE CABLES.
