Lines
Test of the line tensile strength:
Line selection: select a middle, lower cascade of the A, B and a C- lines as well as if available a midd-
le A and B upper cascade, and stress test for tensile strength testing device on their tensile strength.
Tension velocity of the tension cylinder: v=30cm/min
Tear/tensile strength values:
the determined values/modifi cations are to be noted in the inspection!
Attention:
Each size (line diameter) is to be assigned a fi xed value.
In case the lines cannot withstand the indicated load/stress or pass tensile strength test, all other lines
must also be changed. If the checked lines fulfi ll the test criteria, only those are replaced by new lines.
All replaced lines are to be marked in the proximity of the maillon (seam) with a black felt marker
pen and noted in the inspection log with the date of the exchange and the logged of hours of fl ight
time of the glider. During the next test for tensile strength an original line, neighbouring the replaced
line is to be sampled. Th
e various line diameters are allocated a minimal Sewing lenght!
Check of the line length and line attachments
Bottom cascade, upper cascades and brake lines for, breaks, abrasions, visual check. First the A-lines,
then B. etc.
• Are all lines adequately sewn and attached to the line attachments?
• Is the sheathing of the lines even are exactly?
• Are all loops, knots, seams in good shape?
• Are there any abrasions present?
Measuring the line lengths:
• Th
e lines must be measured with a load of 5 kg, in order to obtain comparable results. Th
e rele-
vant line lengths are in the technical data sheet of the uster manual.
• Th
e measurement takes place in accordance with DHV method, from the maillon to the canopy
(inclusive attachment loop at the sail).
• Th
e numbering takes place from the stabilo toward the center. Measuring the opposite facing of
the wing can under same conditions also be conducted by a symmetry comparision.
• Th
e results are again noted the inspection log and should be compared side by side to line lenghts
of the EAPR technical data sheet. Th
e tolerance in deviation of these values should not exceed
more than + /- 1,5cm
• • If a line is defective, it is to be exchanged immediately. Please acquire the identifi cation refe-
rence marking of the line from the line plan, order from the manufacturer and replace accordin-
gly or have it replaced.
Th
e determined values / modifi cations are to be noted in the inspection log!
