Section 4. INSPECTION OF THE WING The sail should be inspected once every three months or after each 50 flying hours. The frame should be inspected once a year, after every 100 flying hours, and after every hard landing. 4.1. SAIL CHECK-UP 4.1.1.
4.3. CHECKING THE TUBINGS To check the condition of the wing tubes the sail should be removed from the wing frame and the tubes should be detached at the joints. The tubes are to be inspected visually. When there is suspicion of damage, the points in question should be inspected using a magnifying glass of (5-10) X magnification.
Section 5. MAINTENANCE 5.1. WING TUNING The Still-17 wing should fly straight and level without any pilot input with a cruising speed of between 60 kph and 75 kph. Before making any adjustments to the wing, first check that the wing is in the standard condition and that the battens all conform to the Still-17 batten template.
5.2. MAINTENANCE With correct maintenance your wing will retain its good condition for many years. We recommend that you do not expose your wing to any more direct sunlight than necessary. Do not leave it standing in the sun for long periods of time when you are not flying it.
If you are in doubt about any aspect of your wing you should consult your dealer or Aeros for advice. Only fly after having attended a good school. Fly a wing suited to your level of ability. A new risk may arise when you first fly a new type of the wing.
