The individual lines are laid out and loaded with 5 daN. The measurement is made from the mount point
of the carrying strap up to the cap including the leash loop. The rib numbering starts in each case in the
Wing center with the wing sides are seen in the direction of flight. The determined total line lengths
are documented in the inspection report and the target line lengths of the corresponding type rating sheet

can be performed by a symmetry check. Compliance with the manufacturer's instructions
The tolerances to be taken shall be documented in the verification report.
• Limit values (tolerance values) may deviate a maximum of +/- 15 mm from the type designation sheet,
whereby due to the tolerances no significant trimming shift is allowed. The tolerances of the brake lines
are +/- 25 mm deviation from the type rating sheet.
• It is restrictive that a fine trimming must be made in 2 cases (the procedure must be followed in the
case of Manufacturer):
o if more than 50% of the lines reach the tolerance limit, with the tolerance limit
may only differ in or - direction (all values of
10-15 mm).
o or 25% of the lines deviate from the tolerance limits in both directions (+ or -)
(Example: A / B lines are 10-15mm longer, while the C / D lines are 10-
15 mm shorter than in the type label (trim shift to the rear due to aging)
Control of the linen strength
