Any idea what caused the bar/line to release/fail??
Yes, Flysurfer glued the high density plastic bar ends into the aluminum bar. No rivet, screw or other secondary mechanism was used to attach the bar end to the bar. I checked the bar end on the right side and found that it was loose.
There are some amazing epoxies out there, but there is something reassuring about a mechanical connection instead of just a chemical one. I am no engineer so I am can't say if it is wrong to use epoxy alone. I just know that I will not trust a bar again that uses epoxy alone to affix the bar ends to the bar.
One thing to keep in mind. Gliding puts a static load on the bar, lines, and kite. Jumping, kiteloops, and powerful jibes put a stronger dynamic force on the bar, lines, and kite. The same thing could have happened while just riding. I shudder to think if another rider were directly downwind of me (while I was just cruising) when the bar end popped loose.
One lesson learned: we cannot be overly diligent in taking time to inspect our gear, even new gear.
Thanks again for the well wishes. We have an awesome local crew. I am proud to be a part of it.
