10. MAINTENANCE
This section contains a recommended schedule of periodic maintenance. None of the items in this section
are a substitute for the continual and consistent practice of proper pre-flight inspections and immediate
maintenance of any items on the wing, which require it. Safety requires that your wing be fully airworthy
for every flight. Nuts and bolts must always be secure, safety rings must always be in place, and damage
to any part, which could compromise the airworthiness of the wing, cannot be tolerated. If you have a
question about the need to repair or replace some part of your wing, feel free to contact your dealer or
Aeros directly. It is not always obvious which items require attention and which may not. Minor dents or
dings in a non-critical location on an airframe tube may not require any repair or maintenance. On the
other hand, a wire that has been kinked one time can fail very quickly after that, and should be replaced
immediately.
We recommend that you have all maintenance work done by your Aeros dealer.
EVERY SIX MONTHS
1. Check the sail washout as described in the last section.
2. Check your battens on a flat level floor against the batten diagram provided, and correct any that
deviate from the pattern by more than 6 mm (1/4").
3. If you fly in a dusty or sandy environment, it will help to prolong the life of your batten pockets if you
wipe each batten with a rag before you install it in the sail.
4. Have a complete inspection performed on the wing and replace any suspension system component
that shows any wear, and any cable that shows any kinks, wear, damage, corrosion, etc.
5. Inspect all bolts for tightness, all safety rings for proper installation and possible damage. Inspect
plates and fittings for damage, holes in tubes for elongation.
6. Inspect the sail for wear, tears, UV damage, loose stitching, etc.
7. Lightly spray all zippers on the wing with silicone spray lubricant. Also spray your battens before you
install them in the wing to lubricate the insides of the batten pockets. Do not use any other type of
lubricant. Wipe off any excess silicone so that it does not attract dirt.
8. Inspect the outboard sprogs. If the sprogs have been loaded heavily, it is possible that the sprog tubes
may have been bent.
EVERY YEAR
In addition to the normal six month service items, also perform the following:
1. Have the sail completely removed from the frame and disassemble all frame components. Inspect
every part of the wing for any damage or wear. Inspect the tubes for straightness and for signs of
corrosion.
2. Anytime you have the sail off the frame, inspect all of the batten pockets and batten pocket
terminations.
SPECIAL CIRCUMSTANCES
1. Any time you suffer a crash or extremely heavy landing you should have an “annual” inspection done
on your wing to insure that you find all damaged parts.
Heavy landings may also impose very high loads on the sprogs and bridle lines. Inspect them
accordingly.
2. If your wing is ever exposed to salt water you will need to have the wing completely disassembled in
accordance with the recommended annual inspection procedure. All frame parts will need to be
