Glider Maintenance Inspection


Glider Maintenance Inspection includes the following

  1. Visual glider check
  2. Porosity 8 point check
  3. All attachment points checked to 20kg loading
  4. Riser check including O Ring replacement
  5. Full line laser length test and glider re-trimmed to factory specifications

A PDF report is provided showing all test results.


Your wing should be technically checked to ensure proper airworthiness. Regular checks will ensure that your wing remains in a good condition and in the correct trim. This will not only make flying safer but it will also give you peace of mind. If you sell your glider, you should poduce an inspection certificate to prove its airworthiness.

Your wing should be checked for the first time after 24 months and every 12 months thereafter. If you are a frequent flyer (more than 80 hours per year), or perform acrobatics or you use a lightweight wing then we recommend that you get your glider checked after every flying season. If your glider is used professionally for training purposes or for tandem flights then a complete maintenance check must be carried out every 12 months. Without this periodical maintenance check, the airworthiness of the glider cannot be guaranteed and it may not conform to the EN/LTF standard that the glider was manufactured to.

We recommend that the maintenance check up is carried out by a qualified professional. You are responsible for your flying kit and your safety depends on it. Take care of it and regularly inspect all of its components. Changes in a wings launching and/or flying characteristics indicates the aging of the glider, if you notice any changes you should have the wing checked before flying again.



A full visual check should be carried out.

This will also help identify any damage to the coating of the cloth. All the components of the wing should be checked: panels; stitching; ribs; diagonals; line attachment points; tabs etc.
Checking for any tears, holes or damaged/loose stitching and repair accordingly. Large areas of damage will need replacement panels. Complex or large scale damage, especially to the ribs or in structurally important areas may need a factory repair. 


The canopy should be measured for porosity values in several different areas of the top and bottom surface. We recommend 5 measurements on the top surface and 3 on the undersurface. The measurements should be made approximately 20 -30 cms inboard from the leading edge in the approximate positions indicated in the diagram below using a porosity meter; this measures the time taken for a certain volume of air to pass through the material.


The overall length (riser lines + mid lines + upper lines) has to be checked under exactly 5DaN of tension. The difference between the measured length and the original length should not exceed +/- 10mm. The length of the line connection tabs is also be included in the measurement. Any significant changes to the overall line lengths will take the wing out of the certified trim configuration and will possibly make the wing more dangerous to fly. The consequences of any changes can include a slower trim speed, difficult inflation, parachutal tendencies etc.

10mm tolerance (overall line length with 5kg tension)


Check lengths and check that the risers are in visually good condition with no abrasion damage, paying particular attention to the maillon hang loops and the main suspension loop. Ensure that all maillons are undamaged and are done up correctly. Replace any missing rubber O rings.
