Under the Stitch Rule, which condition indicates unserviceable equipment?

• A. Three consecutive broken stitches or five stitches in the same area
• B. Two consecutive broken stitches
• C. Four broken stitches in any location
• D. Any single broken stitch

Answer: (A)

Under the Stitch Rule, equipment is considered unserviceable when stitching shows clear, spreading weakness: three broken stitches in a row or five broken stitches in the same area. This threshold is set because a continuous stretch of broken stitches indicates a seam that has lost its integrity along that segment, raising the risk of a seam failure under load. Five broken stitches in one spot similarly signal concentrated damage, making the item unsafe to use until repaired. Two consecutive broken stitches, four broken stitches in any location, or a single broken stitch do not meet the rule’s criteria for unserviceable, so they may require inspection or repair rather than immediate disposal.
