CABLES - CARBON STEEL PER BMS 7-265, TYPE I, COMP A (TZ) (RECOMMENDED)

- CARBON STEEL PER BMS 7-265, TYPE I, COMP A (OPTIONAL) 
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. 

PROOF LOAD AT THE SAME LOAD AS 3/32 INCH CABLES AIRPLANES WITH TWO-PIECE WFA-2/WFB-2 CABLE AIRPLANES WITH ONE-PIECE WFA/B-2 CABLE REFERENCE ONLY. FOR SPECIAL PART NUMBER, LENGTH, MATERIAL
AND END FITTINGS, REFER TO THE IPC.
