Paraglider inspection

When should I send my glider in for an inspection?
After one year, or about 100 hours of use and sun exposure (which ever comes first), or check with us whenever you think your wing isn't performing as it used to.

If you plan to purchase a used glider, have it inspected first.
What are the possible risks if I do not have my glider inspected?
A good inspection will help determine if your wing has any weak spots, which will compromise your safety. Weak spots include:

1. UV damage to lines and fabric
2. High porosity
3. Inner core or outer sheathing damage to lines
4. Stretched and/or damaged lines
5. Seam failure
6. Damage to hardware, such as quick links or pulleys
7. Undetected rips or holes
8. Wing deformities

Weak line strength may cause the lines to break in cascade partially or completely during any wing maneuvers such as wingovers and spirals.

Fabric porosity plays a big role in the way your wing will react and may cause parachutals, changes in wing speed including glide ratio, and difficulties during wing inflations.

Lines that shrink or stretch change the geometry of your wing therefore causing your wing to react differently. This will compromise the safety of your paraglider.

Should I have a partial or full inspection?
When buying or selling a wing, or if you haven’t had your wing inspected in a long time, a complete inspection is in order. If your glider hasn’t been flown much in the last year, you take very good care of it and check it regularly, a partial inspection could be the answer. When in doubt, a complete inspection will give you peace of mind and may save your life.

What does an inspection entail at your shop?
- Verification of the serial number and production date
- Thorough cleaning of the wing (usually done on a wing hoist)
- Complete visual inspection of the top and bottom surface of the fabric and of the interior and cell walls
- Inspect the condition of all seams and stitching
- Porosity test
- Rip test (to check fabric strength)
- Inspection of each line for inner core damage and damage to the outer sheathing
- Measure of each line with a tension weight, comparing them to original line charts and correcting their length
- Line break test (we break “A” main and intermediate lines and measures line strength with a digital sensor - more lines are tested if the results are not favorable)
- Inspection of the brake lines for wear, proper adjustment and length, and attachment to the toggle (our shop will automatically replace both brake lines for free if the glider is two or more years old)
- Inspection of the risers for stretching and shrinkage, inspect all stitching, confirming the integrity of each attachment point and inspecting the trimmers, quick-links, keepers, pulleys, snaps, speed system and toggles
- Replacement of worn rubber O rings

Upon completion, you should receive a written report of the inspection and all repairs with a sticker of “certification/approval” for your paraglider.


Aging of the material

Do all wings age in the same way?
Wing manufacturers use different materials, so each fabric will age differently. The wing has many components; the fabric, the lines and its profile. All these have their individual aging factors. This is why each manufacturer issues a manual with all the pertinent characteristics and statistics of the wing.

Are the paraglider manufacturers responsible for this aging?
Aging of the material is normal and manufacturers do their best to make the wings as resistant to aging as possible. The reason a wing ages prematurely is neglect, abuse and/or ignorance. These factors may result in its safety to be compromised and its life expectancy to be cut in half. The wing owner plays an essential role in its aging process.

What precautions should I take to optimize my glider's longevity?
Kept in the best conditions, an average wing should offer a lifespan of approximately 500 hours. We suggest that after 250 hours, all the main lines be changed.

The principal elements responsible for the premature aging of a paraglider are UV factor, mildew / humidity, heat or severe temperature changes.

Leaving your wing out in the sun when not in use may shorten its lifespan. Packing a wet wing will also shorten its lifespan considerably. One should make sure it is stored in a dry environment, not too hot, nor too cold. Launch sites may be important also and a grassy field is preferable to sand and rocky terrain. Although there is no substitute for a certified inspection, you should visually inspect your wing often between professional inspections.

Can you give me an estimate?
It would be impossible to give an estimate over the phone without seeing the damage. However, if you e-mail one or more pictures of the damage, we can usually give an approximate estimate. Otherwise you’ll need to send us your wing and we’ll contact you with the estimate and get your approval prior to beginning the repair.
