FITTINGS - CORROSION RESISTANT STEEL PER MIL-T-781
CABLES - CARBON STEEL PER BMS 7-265, TYPE I, COMP A (TZ) (RECOMMENDED)
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.
REFERENCE ONLY. FOR SPECIAL PART NUMBER, LENGTH, MATERIAL
AND END FITTINGS, REFER TO THE IPC.
