NOTE:  ZINC-ONLY AND TIN-OVER-ZINC COATED CABLES ARE INTERCHANGEABLE, AND MAY BE INTERMIXED WITH A SYSTEM (AILERON, SPOILER, STABILIZER, ETC.), PROVIDING OPPOSITE CABLES WITHIN A GIVEN CABLE LOOP ARE REPLACED WITH CABLES OF THE SAME TYPE. (FOR EXAMPLE, IN 737 MM27-09-14 FIGURE 202, CABLES EA-2 AND EB-2 SHOULD BE REPLACED TOGETHER WITH BOTH NEW CABLES EITHER ZINC-ONLY OR TIN-OVER-ZINC.) THIS WILL PREVENT ASYMMETRIC CABLE STRETCH THAT CAN DEGRADE SYSTEM RIGGING.
