Sad event.

In the accident report it mentions, "Of the upper lines still attached to the canopy, we can see that the vast majority were incorrectly
mounted." This was listed in the conclusions section as one of the contributing factors.

In the Recommendations section the report says that, "When re-lining a wing, ensure the lines are placed on the attachment tabs correctly. The loop of the lines must be held by the attachment tabs. Lines should not be attached with a lark’s foot as this significantly reduces their strength. If you are unsure of the correct procedure, always consult with a professional."

This is unclear to me what the correct attachment method is. Anyone have the low down?

Thanks, John (OHM)
John,

This video illustrates the right, and wrong way to attach lines. https://youtu.be/o-PjtwytC5M

Dave,

Thanks. That explains all. The right way basically forms what looks like a "square knot" (especially on similar line sizes)

But (there is always a but) - It would seem that the correct way's "square knot" attachment method could, if it become loose, reform itself into the wrong way. That is, if I did it the wrong way, I could reform it into the correct way without having to completely undo the line(s).

While this could possibly happen from time to time it would not have happened on the "vast majority" (per the report) of connections.

Thanks again, John OHM
