Modifications - Ozone OCTANE FLX Betriebshandbuch

We recommend that the check up is carried out by a qualified profes-
sional.
You are responsible for your flying kit and your safety depends on it.
Take care of your equipment and have it regularly inspected. Changes
in a wings flying behaviour, are also indicators of the gliders aging,
if you notice any changes you should have the wing checked before
flying again.
These are the basic elements of the check up (full details and per-
missable figures can be found on our website):
Porosity is measured with a porosity meter, the time taken by a
certain volume of air to go through a certain surface of the cloth. The
time in seconds is the result. A measurement is done in a several
places on the top surface along the span of the glider behind the
leading edge.
The tearing resistance of the cloth - A non-destructive test following
the TS-108 standard which specifies minimum tear strength for sky
diving canopies is executed.
Strength of the line - The centre lines are tested: The uppers, the
middles, the lowers on the A, B, C and Ds are all measured. The
reason for this is because these are the lines which bear most of the
loads.
Each line is tested on a testing table where they are pulled until they
break. The breaking value is recorded. The minimum value is 8 G for all
lower A+B lines and 6 G for all lower remaining lines, calculated from
the maximum certified flying weight of the glider. The added minimum
strength for middle lines and top lines is the same.
If the breaking strength is too close to the minimum value calculated,
the professional will give a period after which you'll have to test the
strength of the lines again.
Lengths of the lines - The overall length (riser lines + mid lines + up-
per lines) has to be checked under 5DaN of tension.
The difference between the measured length and the original length
should not exceed +/- 10mm.
The changes that could appear are a slight shrink on the C and a
slight stretch on the A, B. The consequences of these changes can
include a slower trim speed, difficult inflation etc.
Full check - A full visual check should be carried out: All the compo-
nents of the wing (stitching, ribs, diagonals, lines, tabs, ...) should be
checked.
Finally, if in doubt, a flight test that confirms that the wing behaves
normally can be done by the professional..
IMPORTANT: Take care of your glider and make sure you
have it checked according to the above schedule: This will
ensure you hours of safe flying.

MODIFICATIONS

Your Ozone Octane FLX was designed and trimmed to give the opti-
mum balance of performance, handling and safety. Any modification
means the glider loses its certification and will also probably be more
difficult to fly. For these reasons, we strongly recommend that you
do not modify your glider in any way.
