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)
Strength of the lines - An upper, middle and lower A line, along with a lower B and a lower C (and lower
D if applicable) line should be tested for strength. Each line is tested to breaking point and the value
recorded. The minimum value is 14G for all main riser lines calculated from the maximum certified flying
weight of the glider. The added minimum strength for the middle lines and upper lines should be the
same value. If the breaking strength is close to the minimum value calculated, the professional should
give a period after which the strength test should be performed again.
Lengths of the lines
- The overall length (riser lines + mid lines + upper lines) has to be checked under
5Kg of tension. The difference between the measured length and the original length should not exceed
+/- 10mm.
Risers - Visual inspection for signs of wear or abrasion. Differences to manual lengths should not
exceed +/-5mm.
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.
Finally, a
flight test
to confirm that the wing behaves normally should be carried out by a professional.
Modifications
Your Ozone Zero 3 has been carefully designed and trimmed to give the optimum balance of performance,
handling and safety. Modification will result in a wing that is more dangerous and more difficult to fly. We
strongly recommend that you do not modify your wing in any way.
