3.2. Check
Quality control
Before a glider leaves our company, it is tested and surveyed by Firebird expert technicians. During
the standard quality control, materials and line lengths are checked and inspected so that they meet
approved norms. Any unauthorized and unapproved modifications to Firebird equipment releases
irebird and its staff from any liability and will cancel any warranty provided by the manufacturer.

Pre-flight check
We recommend that all pilots perform routine inspection and maintenance of their glider, especially
before the first flight and after long or difficult flights, after changing their flying technique or have been
in situations which cause pilot concern.
It is always necessary to test a canopy in a practice area after making adjustments of any kind.
In order to keep insure your gliders maximum performance, we recommend the following pre-flight
material check: (To avoid forgetting points, it is useful you always use the same system)
1. Is there any damage to the sewing on the harness or risers?
2. Any knots or damage to the brake lines or brake handles?
3. Are the quick-links closed and not twisted?
4. Any damage to the lines?
5. Any loose stitching, tears or damage to the line connection points on the sail?
6. Any tears in the ribs or sail?
7. Any damage or fatigue on the sail sewing?
In case of any damage, consult the manufacturer or your dealer for advice.
