GENERAL
Dear MAC PARA pilot
We congratulate you on your purchase of a MAC PARA paraglider. Extensive
development work and numerous tests make the Yukon a light weight performance -
intermediate paraglider with maximum possible safety. The Yukon is constructed for
thermal and cross-country flying, and will enable pilots to get maximum enjoyment. The
Yukon offers very easy inflation and simple ground-handling characteristics by take off,
excellent handling in flight and easy landing. Please read this manual carefully before
you start, this way you will get the most out of your glider, and enjoy many nice flights.
MAC PARA wish you many pleasant flights with your Yukon.
Please read this manual carefully and note following details:
Paragliding is a sport, which demands, besides the optimum equipment, a high degree
of attentiveness, good judgement, and theoretical knowledge. Paragliding can be a
dangerous sport, which may lead to injury and death. This paraglider meets at the time
of delivery requirements of the EN (European Norm) 926 or LTF (German Certificate of
Airworthiness). Any alternations to the paraglider will render its certification invalid! The
use of this paraglider is solely at the user's own risk! Manufacturer and distributor do not
accept any liability. Pilots are responsible for their own safety and their paraglider
airworthiness. The paraglider carries no warranty! The author assumes that the pilot is
in possession of a valid paragliding licence for glider's category, insurance etc.
Before delivery, as well as during production, each paraglider goes through a strict
visual inspection, and is test-flown by your dealer. Stamps on the placard, together with
a completed test-flight certificate, confirm this. Check that the paraglider has been test-
flown before your first take-off. If it has not, consult your dealer.
Any inadequate use or misuse increases the risks considerably. The Yukon must not be
used outside the certified weight range. The Yukon must not be used during rain or
snow-fall. The Yukon must not be used in high or gusty winds. The Yukon must not be
used in cloud and fog. The Yukon must not be used by pilots without sufficient
knowledge or experience.
If, after carefully reading this handbook, you still have questions, suggestions or
criticism regarding this product do not hesitate to contact your dealer or us. We will be
glad to help and advice.
MAC PARA wish you many pleasant flights with your
Yukon

Operating limits:
The Yukon is light sport aircraft with an empty weight of less than 120 kg in the category
paraglider. The Yukon has been tested by certification laboratory European Para
Academy to EN-B category. The Yukon is certified for solo flight. The Yukon has been
load and shock-tested and passed with a load corresponding to 8G of the maximum
weight in flight 110 kg. Its flying tests have shown that the glider remains stable and
controllable over a wide range of normal and abnormal flight conditions. Nevertheless,
turbulence and gusting winds can lead to a partial or complete collapse of the canopy.
Therefore never fly in such conditions.
Any changes made to this paraglider invalidate the certificate of airworthiness.

TECHNICAL DESCRIPTION
Construction of the canopy:
The canopy of the YUKON consists of 46 cells over the wingspan. The wingtips are
slightly pulled down and this produces a kind of stabilizer. The Yukon is a second rib
diagonal-construction paraglider. Every second main rib is attached to the 4 or 5
suspension lines. Between these main suspension ribs, intermediate ribs are
suspended by diagonal segments. These segments do not lead to top surface of canopy
but are attached at 80% of rib's height. This construction ensures a smooth top surface
and precise airfoil reproduction. The internal reinforcements maintain the precise form of
the canopy and provide stability. The cell openings on the under-surface of the profile's
nose provide airflow into the glider. Stretch resistant flares, integrated with diagonal ribs
at the suspension points, ensure an even distribution of load throughout the canopy. A
stretch resistant Mylar strip on the top and bottom panels alongside the openings and
running the length of the trailing edge defines the wingspan, together with an optimized
sail tension; this guarantees a high form stability. Large cross ports allow effective
airflow inside the canopy, providing good re-inflation without reducing the profile
accuracy..
The Yukon is mainly made of the proven Nylon fabrics Porcher Marine Skytex 36 E68A,
Skytex 27 E71A and Skytex 32 E29A. Like any synthetic material, this can deteriorate
through excessive exposure to UV.
Rigging system:
The lines of the Yukon are made of proven strong and stretch resistant Dynema and
Vectran lines. Brake lines are from Dynema material. The entire rigging system
comprises individual suspension lines looped and stitched at each end. The
Arami/Polyester main lines have strengths from 140 up to 230 kg. The Vectran cascade
lines have strengths from 53 kg up to 122 kg. The Dynema cascade lines and brake
lines have strengths from 60 kg up to 100 kg

The suspension lines are comprised of “cascaded top lines” (attached to the under-
surface) and “main lines”. Main lines lead loop of riser`s straps or to the “quick link”
(a Maillon which connects lines and risers). The “stabilizer lines” connect the upper
stabilizer lines on the outer suspension points with the quick link. The”brake lines” are
not load carrying suspension lines. They lead from the trailing edge of the canopy to the
main brake lines and run through the pulleys on the D-risers to the brake handles. A
mark on the main brake line indicates the position of the brake handle. This adjustment,
on the one hand, allows sufficient brake to be applied during extreme flying situations
and when landing, while on the other hand, this ensures that brakes are not
permanently applied to the canopy (especially when fully accelerated). This trimming
should not be altered. For differentiation purposes the A-lines are coloured red, the
brake lines are orange, all remaining lines are yellow. Also the main suspension loop,
on the bottom of the riser, is covered red. This is where the main karabiner should be
hooked in, which then in turn connects the risers to the harness.
The Yukon is equipped with 4 strap risers per side (A, B, C, D). The 3 A-main lines per
side are attached to the A-strap. The 3 B-main lines and the stabilizer lines are attached
to the B-strap. The 3 C-main lines to the C-strap. The 3 D-main lines to the D-strap. The
main brake lines leads through the pulleys on the D-strap.
The line connections are made to riser`s strap loops. Second option: The line
connections are made to triangular Maillons (quick links) fitted with a rubber ”o- ring” in
the form of a ”figure eight” which prevents any slipping of the lines on the quick link.
See line plan for details
Speed system:
The Yukon is equipped with a stirrup operated speed-system, which returns
automatically to normal position when the stirrup is released. The serial risers of the
Yukon do not have a lockable trimmer.
The speed system affects the A-, B- and C-risers and changes the angle of attack. In
normal flight all risers have an overall length of 50 cm without quick links. When the
stirrup is pushed out the A-risers are shortened by up to a maximum of 16 cm, the B-
risers by up to a max. of 14 cm, the C-risers by up to a max. of 7 cm, the D-risers retain
their original length. These measurements influence the certification! An incorrectly fitted
speed system causes loss of certification!

Fitting the speed-system:
Most modern harnesses have pulleys attached for speed system fitting. In case not, it is
important to attach pulleys (sewn on tabs) in such a way that they allows the pilot to
maximize the power vector of his / her legs without ”pushing back” in the harness.
The Yukon speed system, including Brummel-hooks supplied, must be assembled as
per instructions.
The speed system cord is firmly attached (use bowline or other nonslip knot) to the foot
stirrup (webbing or alloy bar). The other end of the cord is run through a pulley on the
harness and then in an upward direction to be then firmly attached to the Brummel-
hooks!
The length of the cord leading to the stirrup should be adjusted so that it is easy to put
your feet into the stirrup in flight but still short enough to allow full speed system travel.
(Use of 2 stirrups in a ladder fashion can enable you to reach the full range if your legs
are not long enough.) Ensure both cords on the stirrup are of equal length, to avoid
putting a turn in the glider.
Test your speed system for the correct length of cord on the ground first (simulating
flying position), with your harness and risers, before flying with it! The full range is
reached when the 2 pulleys join together.
Before launch, attach the paraglider's risers to the harness with the main karabiners.
Then attach the ”Brummel-hook” on the end of each speed system cord to the Brummel
hook on the end of the cord which runs through the 2 pulleys on the A risers. Ensure
that the speed system is untangled and operates freely before flying!

HARNESS
The Yukon is certified with LTF GH type certified harnesses. Nearly all harnesses
available on the market are „GH“.
These “GH“harnesses are different to “GX“ harnesses, which have a lower attachment
point for the main karabiners and effective cross bracing. The Yukon was not tested with
harnesses with an effective cross bracing system.
Any certified harness with a hang point at about chest height may be used with the
Yukon (37-50cm over seat plate). The distance between left and right main karabiners
should be between 45 and 60cm, depending on the size of the pilot and the type of the
harness. Please note: the hang point position changes the position of the brakes relative
to the pilot's body.
