GUIDELINES FOR PARAMOTORING GLIDER CHECKS
Porosity measures should be taken on at least three points of both the top and bottom
surface. The first point should be placed 20-30 cm from leading edge in the middle of
canopy. Second and third points are placed left and right from first measure point at
25% of the span. One additional measurement should be made on the top surface of
the wing tip.
The identified time should be higher than 30 seconds (JDC). In the event of the result
being less than 30 seconds, the result of the check is a fail.
Overall strength check
The top and bottom canopy strength check should be made with a Bettsometer
(B.M.A.A approved Patent No. GB 2270768 Clive Betts Sales), a small hole with a
needle at the A-line attachment points. The exact verification should be made in
accordance with the Bettsometer user manual. Consult your local paraglider inspection
facility.
Line strength check
Line strengths should be as specified in accordance with the certification requirements.
One main line should be taken from each array and have its strength checked with a
tension-meter.
Required strengths should be higher than:
A + B main lines x measured value > 8 x maximum take-off weight and higher
than 800 kg for the A + B arrays.
C + D mean lines x measured value > 6 x maximum take-off weight and higher than
600 kg for the A + B arrays.
Replacements for damaged lines must be with new original lines. Line lengths are taken
from the lines data page.
Line length measurement
Lines should be separated and each line measured under a tension of 5 kg.
Measurement is made from the line carabineer to the canopy according to the method
of certification. Rib numbering begins in the middle of canopy and leads to the wing tip.
Measured lengths of the lines should be documented in the inspection record and
compared with certified full line lengths protocol. Lengths should not differ by more than
20 mm. The opposite side of the paraglider should be checked for symmetry.
Canopy line-attachment points check
Attachment points should be checked for damage and stretching. Defects, loops and
flares should be repaired.
