7. DE-RIGGING THE AIRCRAFT
WARNING
!
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 technique 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.
7.1. DE-RIGGING
The de-rigging procedure is a direct reversal of that for rigging. As with the preparation before
flight, it is also important when de-rigging that the pilot/operator carries out an inspection.
The aircraft may be fitted with an optional rigging gas strut. If a gas strut is not
fitted, support the weight of the wing by lifting on the control bar from the moment
you unhitch the front strut, or damage/personal injury could occur.
Face the aircraft into wind and apply the parking brake. Remove the windscreen extension, if
fitted. Remove the 2 rings and pins holding the front strut to the front strut lower. These can be
found above the panel and behind the windscreen. Undo the pylon overcentre lever. Remove the
pin at the top of the front strut and remove it.
Stand in front of, and facing the trike, with both hands firmly supporting the control bar. Gently
ease the control bar towards you as you walk backwards until the keel has engaged with the keel
stop and the pylon starts to move towards you. If a rigging gas strut is fitted, while keeping firm
control of the descent with both hands on the control bar, you can allow the gas strut to support
the weight of the wing. If no gas strut is fitted, then you will be supporting the wing weight all the
way to the ground.
Do not attempt to lower the wing to the floor without a rigging gas strut if you have back problems or if you are slight in
stature. With wind input, you could find yourself with up to 97 lb (44 kg) of dead weight to carry. If you are unfit to carry this
weight in a stooped position it is essential that a gas strut be fitted, or that someone else is on hand to help you.

CAUTION
For the first few times that you de-rig your
aircraft, ensure that the weather is calm or you
have an experienced helper to take charge if
the wind starts to take control from you. It is
also much better to be set up on a grass than
hard standing, both to avoid damage to the
wing and scraped knuckles as you lower the
wing to the ground. Clear the area of clutter,
wing bags, tools, twigs and inspect the ground
for holes or any other obstacles that may trip
you.
