PAY ATTENTION_
A fixed value is assigned to each size (line diameter). If the lines
cannot withstand the specified tensile load or tear resistance, all other lines must also be
replaced. If the tested lines meet these test criteria, only the others will be replaced by new
ones. All replaced lines must be marked near the shackle (seam) with a black pen and noted
in the test report with the date of the exchange and amount of flight hours from the device.
At the next check, an original line nearest to the replaced one is used for the line strength
test. A minimal sewing length is assigned to the different line diameters!

Checking line lengths and fixings
Visually inspect the main, cascade and brake lines for cracks, kinks and chafe marks. First the
A-line level, then B. etc.
1.)
are all lines and their fixings sewn and attached correctly?
2.)
is the coating of the lines intact?
3.)
are all loops, knots and sewing in good condition?
4.)
are there chafe marks?

Line length measurements:
Measuring the line lengths is part of the regular data check. The lines must be measured with
a load corresponding to 5 kg in order to obtain comparable results. You can find the
corresponding line lengths in the aerial sports equipment description sheet in your manual.
1)
The measurement is carried out according to the DHV method from the (line) shackle
to the cap (including the line loop on the cap).
2)
The numbering is from the centre of the screen to the Stabilo. The measurement of
the opposing wing side can also be carried out under the same conditions by a
symmetry comparison
3)
The result is noted again in the test protocol and compared with the nominal line
lengths of the DHV-data sheet. The tolerance deviation should not be more than +/-
1.5 cm
4)
If a line is defective, it must be replaced immediately. Please take the description of
the lines from the line plan, order from the manufacturer and then install or have them
installed accordingly by authorized professionals.
The specified values / changes are to be noted in the inspection report!
