Checking The Glider - Air Design Pure3 Betriebshandbuch

For cleaning, only use a soft sponge and clean water.
Do not use solvents, cleaners or abrasives.
Repairs:
Repairs must be done exclusively by the manufacturer, importer or authorized persons.
Use only original parts.
In case of questions, please contact AIRDESIGN directly.
Material Wear:
The PURE3 consists mainly of Nylon cloth.
This material does not lose much strength or become porous through exposure to UV
radiation. However, despite this, you should take care to not expose the glider unnecessarily to
sunlight. Unpack shortly before take-off and pack the glider right after landing.
The PURE3 is lined with unsheathed Aramid lines. Take care not to stress any line mechanically.
Overloading should be avoided as a stretching is non-reversible. Continuous bending of Aramid
lines at the same spot weakens their strength.
When putting the glider to the ground, avoid dirt and dust as much as possible. Dirt can get
between the fibres of the lines, which may shorten the lines and damage the covering.
When lines get caught during take-off, they can stretch or even break. Do not step on lines.
Sharp edges on the ground can damage the sheathing.
A brake line tangled around other lines can tear or cause damage.
Take care that no snow, stones or sand get into the canopy. The weight can pull down the
trailing edge and slows the glider. In the worst case scenario, the glider can be caused to stall.
When launching in strong winds, the canopy can, if not controlled, overshoot and hit the
ground hard. This can lead to tears in the ribs or damage the sail or stitching.
When landing, avoid the leading edge hitting the ground in front of you. This can damage the
materials in the leading edge.
After landings in trees or water the line length must get checked. After contact with salt water
wash the glider immediately with clean water.
Avoid contact of fabric with sweat.
Do not pull the glider over rough ground; his can damage the cloth at the contact points.
Do not pack the glider too tightly.
The total line length documents for each size of the PURE3 are found in the annex.

Checking the Glider

Even with the best possible care, each glider is subjected to a certain aging which can affect the
flying characteristics, performance and safety.
A thorough inspection of all components, including checking suspension line strength, line
geometry, risers geometry and permeability of the canopy material is mandatory.
Glider Inspection:
After 12 months or 150 flight hours the glider must be inspected. This check will be made by
the manufacturer, importer, distributor or other authorized persons. The checking must be
proven by a stamp on the certification sticker on the glider as well in the service book.
In the event that a glider is NOT checked according to this schedule, the airworthiness
warranty of the glider is invalidated.
