Module 11. Aeroplane aerodynamics, structures and systems

Excessive wear on both sides of the control cable pulley groove is evidence of

  • pulley misalignment.
  • excessive cable tension.
  • cable misalignment.

Explanation

If a pulley is misaligned, the cable enters and leaves the groove at an angle and rubs against both side flanges, producing wear on both sides of the groove. Excessive tension or a fairlead/cable problem tends to wear the groove base or chafe the cable, not symmetrically wear both groove flanges.
