For a 7/32 inch flight control cable, what load test value would be used?

• A. 3360
• B. 1680
• C. 3200
• D. 4000

Answer: (A)

For a flight control cable, the load test value comes from the published minimum breaking strength (MBS) for that cable size. A 7/32 inch control cable has an MBS of 3,360 pounds, so the standard test load used for verification is 3,360 pounds. The other options don’t match the published MBS for this diameter (half the MBS would be 1,680 pounds, and 3,200 or 4,000 pounds are not the specified MBS for this size). Using the MBS as the reference ensures the cable can safely handle its expected loads with an adequate safety margin.
