Checking The Glider - Airdesign UFO 21 Betriebshandbuch Und Serviceheft

unnecessarily to sunlight. Unpack shortly before take-off and pack the glider right after landing.
The UFO 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 the 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 the pilot. This can damage
the materials in the leading edge.
After landings in trees or water the line length must be checked. After contact with salt water
wash the glider immediately with clean water.
Avoid contact between the fabric and sweat.
Do not pull the glider over rough ground; his can damage the cloth at the contact points.
Do not too pack the glider too tightly.
The total line length documents for each size of the UFO are found in the annex.

Checking the glider

Even with the best possible care each glider is subjected to a certain ageing which can affect
the flying characteristics, performance and safety.
A thorough inspection of all components, including checking suspension line strength, line
geometry, riser geometry and permeability of the canopy material is mandatory.
After 24 months or 100 flight hours (whichever occurs first) the glider must be inspected.
This check will be made by the manufacturer, importer, distributor or other authorised
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.
More information about servicing and inspections can be found in the document "Inspection
Information" available on the AIRDESIGN website www.ad-gliders.com
Ground-handling times must be multiplied by factor of 2 due to the greater contact with
abrasive surfaces.
