MANUAL FOR PARAGLIDER CHECK
Check-intervals
All paragliders used in flight must be checked at least every 24 months. For paragliders
used by paragliding schools the period is 12 months.
Personnel authorised to carry out checks
A valid flying license and training course by National association are the basis for
permission to carry out paraglider checks
Identification of glider
An identity sticker with details of certification and serial number is attached to the glider.
Components of the check
Porosity
The porosity should be checked with a porosity meter (JDC). Compare the resultant
data with the producer's manual.
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 second (JDC). In the event of the result
being less than 30 seconds, the result of the check is a fail.
Overall strength check
The check of canopy strength should be made with a Bettsometer (B.M.A.A
approved Patent No. GB 2270768 Clive Betts Sales). On the top and bottom
surfaces make small holes with a needle at the Aline attachment points. The
exact verification should be made in accordance with the Bettsometer user
manual.
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
then 800 kg for the A + B arrays.
•
C + D mean lines x measured value > 6 x maximum take-off weight and higher
then 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.
