The determined values/ changes are to be noted in the inspection report!
Checking the ribs:
1)
Visual inspection of the chambers (from the entry to the rear edge) to see
whether the inner seams, cell partition walls and stiffeners are in good condition,
i.e. without cracks, stretching, straining, chafing, damage to the coating
2)
If the ribs are torn, the sewing/ stitching is defective, lose or missing, the glider
must be sent to the manufacturer or an authorised dealership or competence
centre
3)
The specified values / changes are to be noted in the inspection report!

Tear resistance control
To be carried out with the bed meter at the following points (B.M.A.A. approved patent
number GB2270768 Clive Betts Sails). The test sequence can be found in the operating
instructions for the bettsometer.
1)
Punch a needle-thick hole in the upper and lower sails of the A-line linkage and
check the tear resistance
2)
The limit value of the measurement is set to 500 g, and a crack length of less
than 5 mm
The specified values / changes are to be noted in the inspection report!

Canopy porosity measurements
At all subsequent measuring points, the air permeability should be higher than at least 20
seconds (after Kretschmer). For smaller air permeability values, the paraglider must be sent
to the manufacturer. Measuring points: The porosity measurements according to the
Kretschmer measuring method (please observe the operating instructions) should be
carried out at the following points on the cap. Perform tests on the lower and upper sails:
1)
middle cell about 20 - 30cm behind the leading edge
2)
3rd cell from the middle left/ right approx. 20 - 30 cm behind the leading edge
