6.2. WING RIGGING
Rigging and de-rigging the aircraft is a simple and safe operation when carried out
correctly. However, if you do not use the correct procedures or techniques it is possible to
injure yourself. It is therefore essential that you receive formal instruction on how to rig and
de-rig the aircraft by an instructor, P&M dealer or other competent person before attempting
the operation on your own.
1.
Select a clean, dry area and lay the wing down, opening the zip to reveal the control
frame and underside of the wing.
2.
Open out the control frame and attach the base bar to the corner joints. Inspect the
basebar holes for damage.
3.
Lift the wing from the front and rotate it so that the wing is now laying on the ground with
the assembled control frame flat on the ground underneath.
4.
Remove all the sail ties and open each wing about a metre. Lift the kingpost to its upright
position and attach the rear top rigging cable to the cable end protruding from the top of
the kingpost. Tighten the shackle.
5.
Ensure that the upper cables are free from kinks and that the over-centre lever is in the
open position.
6.
Open the wings in stages, alternating between wings to prevent damage to the
crossboom and fittings. Stop and check if any undue resistance is felt.
7.
Ensure that all wires are untangled, particularly at the connections.
8.
Excluding the nose rib, fit all the top surface ribs starting with the outboard main ribs and
working in-board towards the root. Do not force the ribs if they seem hard to push fully
home.

WARNING
!
The
base
bar
is
a
component. Any damage of any kind - bends,
dents, deep scratch marks and signs of stress
around the holes - means the base bar must
be replaced before the next flight.
CAUTION
Damage may result to the sail and to the ribs if you
force the ribs into the sail. Investigate immediately if
undue resistance is felt, and if undue resistance
occurs when the ribs are nearly home, leave them at
this stage until after the wing has been tensioned at
a later stage.
