What is required for the UH-60 apex hookup?

• A. Aluminum spacer
• B. Steel shim
• C. No spacer required
• D. Plastic washer

Answer: (A)

The key idea is proper spacing to ensure correct alignment and safe load transfer at the apex hookup. An aluminum spacer is required because it provides the right clearance and compatibility with the other aluminum hardware, keeping the apex assembly properly aligned and protecting surfaces from wear. Using a steel shim would add unnecessary weight and could lead to galvanic corrosion or damage to aluminum parts. A plastic washer wouldn’t withstand the load or maintain the required geometry and could deform. No spacer would fail to provide the needed clearance, risking interference and improper load distribution.
