GUIDELINES FOR PARAMOTORING GLIDER CHECKS
Check-intervals
All paramotoring gliders used in flight must be checked at least every 24 months. For
paramotoring gliders used by paramotoring schools the period is 12 months.
Personnel authorised to carry out checks
A valid flying license and training course by National associations are the basis for
permission to carry out paramotoring glider checks.
Identification of glider
An identity sticker with details of certification and serial number is attached to your
glider.
Components of the check
Porosity
The porosity of your glider should be checked with a porosity meter (JDC). Compare the
results 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 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.
