it is not, physically pick up the center and drag it into
the center position. Then go to the end of the side that
will be bunched up and pull out the slack.
Remove the protective sleeves that cover the suspension
lines and their components. The protective
sleeves are referred to as line sleeves and there is a
line sleeve on each set of lines (or two—
the right and
the left). [Figure 5-15]
While laying out the wing, check for tears in the fabric,
torn or loose stitching, abrasions, and deterioration
of the fabric from ultraviolet rays. The sun is one
of the powered parachute wing’s worst enemies, next
to the prop! Certain colors deteriorate faster than others,
like red and orange, when exposed to ultraviolet
rays from the sun. When the wing is not being used,
you should always return it to its wing bag. Take this
opportunity to check the wing cells for debris, such as
stones, sticks, and bugs; lifting the wing by the trailing
edge and gently shaking it will allow most captured
debris to fall out of the ram-air openings on the
leading edge of the wing.
With the wing centered behind the cart, it is time to
start checking the suspension lines. At first glance
it may look difficult to sort out all of the lines from
the cart to the wing. Most of the time, the lines will
straighten out with just a light flick of the wrist. Make
sure you have no twists or line-overs and your lines
are straight. As long as the wing has not been physically
removed, or disconnected from the cart, there
should not be any permanent knots in the lines. In
the event that you detect pressure knots during the
line inspection they are easily removed with minimal
manipulation.
Small twigs, stems from weeds, and other debris can
get caught in the lines to form pressure knots. Pressure
knots are a concern because they are only “knots”
when there is tension on the lines. That means they are
only a problem when your wing is inflated. As soon
as you land, the foreign object often shakes free and
there is no knot. However, while you are flying, that

pressure knot can cause the powered parachute to go
into a steep turn. Make sure there is nothing around to
catch into your line sets. The more organized the suspension
lines are laid out during this preflight check,
the more likely that the wing will kite evenly and
without mishap. It may take a great deal of space to
get all the cells open during the inflation of the wing.
Aborting the takeoff to re-kite the wing is always an
option, but it is not desirable. Preflight the wing correctly
the first time.
If you put your wing away correctly and took it out
as described, it should not have any twists in it. However,
you still need to check. Start where the risers attach
to the cart. Make sure they are not twisted around
anything and trace each one back to the point where
the wing risers are attached to the cart.
Check the steering lines on both sides of the cart;
make sure the anchor point knots are secure and the
lines flow freely through all guides and pulleys. Make
sure the links on both sides of the aircraft are secure;
it is recommended that the links are finger tight plus
one-quarter turn. Continue by checking that the riser
cables are not twisted or damaged and they are free
from tangles. At this time pull slack from the steering
lines so the steering bars are fully retracted. Physically
separating the steering lines from the suspension
lines, pulling them out and away to the outer edge of
the wingtips, enables you to visually see the steering
lines are free from being tangled with the rest of the
lines. [Figure 5-16]
Continue to check the suspension lines for tangles,
knots and wear and the attachment points for security
and lack of fraying. [Figure 5-17] The A lines should
be visually and physically separated from the B lines
at the point where the lines are connected to the risers.
Most newer wing lines are color-coded to make
this process visually easier; the older wing styles will
still be separated and configured the same way as the
newer wings, however all the lines will be the same
color. The A lines will travel toward the leading edge
of the wing and subdivide into the C lines. The B lines
will travel toward the trailing edge of the wing and
