2. Inspect the cable routing to ensure that cables (at the left, right, and crossover pulleys) are correctly routed around the pulleys, within the cable guide pins, and are not contacting any structure.

Background: The FAA received a report of an in-flight separation of the elevator trim tab control cable on a Beech 1900D aircraft. An investigation revealed that the trim tab control cable had separated in the vicinity of its guide pulley, due to being incorrectly routed outside the lower cable pulley guard pin instead of under the guard pin.
