Ozone Swift Six - MAINTENANCE CHECKS; Routine Maintenance Schedule; Line and Porosity Checks

24
It is important that replacement lines are made from the correct materials and diameters. You should
check lengths against their counterpart on the other side of the wing to make ensure symmetry. Once the
line has been replaced, inate and check the glider before ying.
Maintenance Checks
Your wing, like a car, should be technically checked to ensure proper airworthiness. Your wing should
be serviced by a qualied professional for the rst time after 24 months, or after 100 hours. However, if
you are a frequent yer (more than 100 hrs per year), then we recommend you have the wing serviced
annually. The checker should inform you about the condition of your glider and if some parts will need to
be checked or changed before the next normal service check period.
The dimensions of the lines tend to move during the rst part of their life, it is therefore recommended to
have a performance trim check within the rst 50hrs of use. To ensure the correct trim, the lines should
be measured and adjusted to the published values as necessary. Loops in the C lines, along with loops
attaching the B risers are in place to make the trimming process easier.
During the life of the wing the sail cloth and the lines do not age in the same way or at the same rate, it
is possible that you may have to change part or all of the lines during the wing’s life. For this reason it is
important to do regular inspections so that you know the exact condition of all of the components of your
glider. We recommend that inspections are carried out by a qualied professional.
You alone are responsible for your ying kit and your safety depends on it. Take care of your equipment
and have it regularly inspected. Changes in ination/ground handling/ying behaviour indicates the gliders
aging, if you notice any changes you should have the wing checked before ying again. These are the
basic elements of the check up:
Porosity is measured with a porosity meter, the time taken by a certain volume of air to go through a
certain surface of cloth. Measurements are made in several places along the top surface of the the leading
edge.
