Maintenance
Identification label
MAC PARA gliders have an identification label on central rib. It is helpful to provide the
type designation of the paraglider if you are contacting your MAC PARA dealer with any
queries or ordering replacement parts or accessories, to ensure accurate identification.
Regular inspections
Risers and quick-links, lines and fabric must be inspected regularly for damage, abrasion
and correct operation.
Tissue and Canopy check
A full visual check should be carried out: All the components of the wing (stitching, ribs,
diagonals, lines, tabs, ...) should be checked for signs of deterioration.
The tearing resistance of the cloth - A non-destructive test following the TS-108 standard
which specifies minimum tear strength for sky diving canopies should be made using a
Bettsometer. (B.M.A.A. Approved Patent No. GB 2270768 Clive Betts Sails).
Risers
Visual inspection for signs of wear or abrasion. Differences to manual lengths should not
/-5mm.
Lines
Measuring the length of the lines is part of the regular paraglider inspection. The overall
length (riser lines + mid lines + upper lines) has to be checked under 5 kgs of tension, in
order to ensure reproducible results for a comparison with the lengths in the check sheets.
The lines have a considerable influence on flight behaviour. Correct line length and
symmetry are also important for performance and handling. Therefore we recommend an
geometry inspection every 50 hours or once a year.
Strength of the lines - An upper, middle and lower A line, along with a lower B line should
be tested for strength. Each line is tested to breaking point and the value recorded. The
minimum value is 14 G for all A+B lines, calculated from the maximum certified flying
weight of the glider. The added minimum strength for the middle lines and for the top lines
should be the same. If the breaking strength is too close to the minimum value calculated,
the professional should give a period after which you will have to test the strength of the
lines again.
Lengths of the lines - The difference between the measured length and the original length
should not /- 10mm. The changes that could appear are a slight shrink on the B’s
and/or a slight stretch on the A’s. The consequences of these changes can include a
slower trim speed, difficult inflation etc.
