What are FailSmart lines?

FailSmart is the name of JYRO’s new hybrid lineset update designed to improve safety by reducing the risk of low-altitude line failures.

After reviewing user data, conducting lab tests, and assessing real-world wear, we’ve updated specific lines in our V400 and V300 linesets to better handle high stress loads over time — particularly those experienced during performance turns.

What's Changed?

Thicker A1 lines:

• On V400 linesets (used on Leia): A1 lines are now made from V550 instead of V400.
• On V300 linesets (used on Petra): A1 lines are now made from V400 instead of V300.

The rest of the lineset remains the same. This is a structural safety enhancement, not a material change across the full lineset.
 

Why the Change?

While visual inspections often fail to show wear on highly-loaded lines, our testing revealed that A1 lines are consistently the most loaded, especially in flight. Failures of these lines — while rare — can occur close to the ground and leave little margin for recovery. By using a thicker line in that specific location, we’re moving the weakest point and increasing your odds of catching a failure before it becomes dangerous (during deployment).

Does This Affect All Products?

Yes — FailSmart is now standard on all new linesets and canopies using V400 or V300:

• JFX 2 (V400 linesets only)
• Leia  (V400)
• SLeia (V400)
• Petra (V400 + V300)

You’ll receive the updated FailSmart configuration automatically when ordering new V300 or V400 linesets or a new canopy with those lines.

Anything Else I Should Know?

• There is no additional cost.
• This does not extend the total lifespan of your lineset. Always inspect and replace based on wear, jump numbers, and manufacturer recommendations.

NOTE: FailSmart lines are currently implemented on V300 and V400 linesets used on high-performance canopies like Petra, SLeia and Leia (and on JFX 2s with V400 lines). That’s because these pilots tend to load their wings higher and generate more force—especially during high-speed landings—putting extra strain on lines right when it matters most. We’re not seeing the same kind of line failures on other, lower-performance canopies, so FailSmart isn’t required there.
