Issue with Naish Kite leading edge, manufacturing defect ?

Postby merkliorer » Thu Nov 16, 2017 8:21 am

Hello All,

My friend had an issue with her Alana Kite. It seems the leading edge exploded during inflation.

Do you think this could be a manufacturing defect or something else? Do you think there is a chance that Naish takes it under warranty?

How old/new or how many sessions? Was there a max psi like 7 or 8 indicated, that the manufacturer specified? From the pictures it looks like a defect. I’ve never used Naish products but it looks like you should read through your warranty. A burst like that is what I’d expect out on the water from careless use, not at all something that should be possible simply pumping up the bladder.

Is it a 2015 or 2016 Alana? They didn’t make it for ‘17 anymore. I assume it is well used?

What do you mean by defect ChickenD? If manufacturing I’m interested to learn what leads to that conclusion?

With all my respect I do not thinks that it is possible to tear the leading edge like that during inflation.
And I am curious why do you write "It seems..." If it is during inflation, your friend should know that for sure. :D

More likely the reason is a high speed crash into some hard, sharp object on the ground.

From the picture it looks like there's been a point loaded impact (to the left of centre?) which has weakened the leading edge enough for the bladder to blow out and thereafter tear the leading edge following slightly offset weave (weft?) lines towards each leading edge reinforcement patch.

It’s not a manufacturing defect when the rip is in the middle of a panel. You can see it’s not on the seam.

So it is from an undected nick in the material from something on land, that becomes a massive blowout when under pressure.

:thumb:

The high pressure, needed to tear the leading edge like that can not be created with a hand kite pump (when slowly and gradually increasing the pressure up to a relatively low maximum value). It can only occur in the moment of a high speed crash into the ground, when we have sudden and massive pressure increase.

Could be some debris on beach or a bad manucure job :lol:
It s tough one, I have crashed my kites many times and never got a blown out, mostly seams getting loose and weird ernia around seams. I don't really inflate my kite rock solid though.

So on pic we can't see the sides but looks like tear started right in middle of panel following shape of bladder when air escaped?

It was cut, I can see it in the photos. Not a warranty.
