Evaluation of the measurements for the top sail:
JDC Kretschmer Evaluation
15-30 50-100 Strongly used
<15 <50 Not sufficient
If the result is “strongly” used, this has to be recorded in the check protocol. In
this case, the next check has to be scheduled one year later.
If the result is “not sufficient” the glider looses its airworthiness. This has to be
recorded in the check protocol as well.
Checking the cloth strength
Checking the cloth strength is carried out with the so called betsometer on one
spot on the top sail and on one spot on the bottom sail. Both spots should be
chosen in the middle of the wing (front section). If the cloth tears at a load of
600g, the strength is not sufficient and the glider looses its airworthiness. If the
cloth does not tear at 600g the glider passes and the test shall be aborted. The
result has to be entered in the check protocol.
Visual inspection of the canopy
The canopy has to be checked for damages which might affect the
airworthiness of the glider. This contains damages on the top sail, the bottom
sail, the ribs, the diagonal ribs and all seams. (Especially in the area of the cell
openings, as well as the seams of the suspension loops on the bottom sail.)
Small tears and holes (up to about 5cm) on the top- or bottom sail can be
repaired with “NOVA adhesive repair tape”. If the tear is bigger than 5cm or if
it is close to a seam, the repairing has to be carried out by NOVA or by an
accredited repair centre. (Same for damages on the ribs, or diagonal ribs.)
Every damage and repairing has to be entered in the check protocol.
