11.3 Jacking the Aircraft
Either of the main wheels can be brought clear of the ground by one person lifting the wing at the top
of the wing struts. (Never apply any significant up load to the centre of the struts). The aircraft can then
be chocked by placing a wooden block under the bottom part of the stub axle. This is also a suitable
jacking point where a second person is not available to lift the wing.
The nose wheel is easily lifted by applying a load to the rear fuselage, just forward of the tail. Where one
person only is available, place weights on the tail, suitably padded to prevent damage to the fabric,
until the nose wheel becomes light. Place a piece of timber under the tail skid, then push the tail down
on to it. Add further weights to the tail to stabilise the aircraft in this attitude.
11.3 Cleaning and Repair of the wing fabric
Cleaning
Clean the wing coverings with warm water and a mild detergent, such as washing up liquid, to remove
oil. Never use solvents. All metal parts are anodized aluminum or stainless steel and need no special
attention.
Dirt or mud on wing surfaces should be removed with clean water. Avoid the use of a pressure washer
or hose pipe as this can introduce water into places it shouldn’t go, (engine, fuel tank, pitot head, pilot’s
seat).
Repair
Repair even the smallest tears in the covering fabric.
Carefully clean the area around the tear, then attach a small patch with contact adhesive covering an
area at least 15 mm larger than the damage all round. Alternatively apply a small patch of
self-adhesive material. For larger areas of damage, consult the importers, Red Aviation .
In the event of technical problems, contact Red-Air .
