Check of the line condition
The paraglider has to be spreaded and every single line has to be checked. The
lines have to by manually scanned on their whole length. If you detect a
damage, on the coating or on the core, the line has to be replaced. Furthermore
the sewing and the line loops have to be controlled.
Every damage and repairing has to be entered in the check protocol.
Measuring the line strength
The ripping test has to be carried out at the first NFS. (so 2, or 3 years after
purchase)
How to perform the ripping test:
One lower line and one mid line have to be ripped. The A-lines in the centre of
the wing are the ones with the most loads in flight, so you have to rip the A1
and the A1M (inner mid line).
Attention: If a glider has just two line levels, (only lower lines and top
lines, e.g. Mentor 2) the ripping test has to include the top level. The
strength of the top line has to meet the criteria which are required for the
mid lines on a glider with three line levels. (See explanation below)
In other words: If there are just two line levels, the top lines have to be
treated the same way, like the mid lines on a glider with three line levels.
If you check an old glider, make sure, you don’t rip a line, which has been
replaced in a former ripping test!
To avoid that a priori we recommend, ripping the A1 lower line, and A1M mid
line on the right side for the first ripping test. For the next test, rip those lines
