What should slack between support points NOT exceed?

• A. 0.25 inch
• B. 0.5 inch
• C. 1 inch
• D. 2 inches

Answer: (B)

Slack between support points should be kept very small to prevent movement when loads are applied or the aircraft vibrates. The best limit is about half an inch. This amount lets you account for small manufacturing tolerances and slight deflections while ensuring all supports stay in firm contact, distributing the load evenly and preventing shifting, rubbing, or misalignment of the part. If the gap is larger, the component can shift under dynamic loading, which can cause improper seating, increased wear, or even damage. A smaller gap, like a quarter inch, can be harder to set but is still acceptable in some cases; anything much larger—one inch or more—allows noticeable movement and is not acceptable.
