Narrative:
[This aircraft] has both port and starboard side flight control cables (2 on each side) which run back to the aircraft stab routed improperly through the phenolic block. The phenolic block has two halves one for each cable; however on this aircraft and two others in the past; both cables ran through only one half of the block. This routing leaves little to no clearance of the flight control cables and they will rub against one another. There is no clearance between these two cables on the starboard side. The phenolic blocks locations are the first set of phenolic blocks above and forward of the air cycle machine on the cessna 680 aircraft.I suggested in my last report that a onetime inspection of all ce-680 aircraft be conducted for improper cable routing. I would also suggest a periodic inspection in case these routings are symptomatic of some other issue like control cable removal and replacement or tension checks.
