Below is a summary of reserve maintenance/life/testing limitations as per the available manufacturers' manuals.

Icarus
Canopies:
  • Icarus Reserve
Life limit:
  • None
Porosity Testing:
  • None required
Fabric strength testing:
  • None required
Limits of repair:
  • Not Significant: Damage that may be left unrepaired. Small snags and holes smaller than 3 mm2 (one ripstop box) located further than 25,40 centimetres from the closest line attachment may be left unrepaired as long as there are no more than one snag or hole in any 25,40 centimetres circle. A maximum of three such snags or holes per cell are allowed. Ripstop tape is not authorized for use on this reserve.
  • Minor Repairs: These may be performed by a senior rigger, master rigger, or foreign equivalent. Any hole or tear up to 25,40 centimetres in length may be repaired by as long as the closest area of the completed repair is at least 2,54 centimetres from the nearest seam and at least 12,70 centimetres from the nearest tape or line attachment. A maximum of 3 such repairs per panel or 15 per canopy are allowed.
  • Major Repairs: These may be performed by a master rigger or foreign equivalent. Any repair to line, tape or webbing damage is considered a major repair. Master riggers or their foreign equivalent may perform repairs that do not involve taking apart any bartacks on the canopy. Special bartack patterns and thread types are used. Any other type of bartack will affect the strength of the parachute. In addition, removal and replacement of these stitch patterns usually weakens the fabric to the point that it is necessary to replace portions of panels.

Performance Designs
Canopies:
  • PD Reserve
  • Optimum
Life limit:
  • None
Porosity Testing:
  • Must be checked after 25 uses or 40 repacks.
Fabric strength testing:
  • Annual fabric strength pull test along the warp at 30lb in 2 places on each colour.
Limits of repair:
  • Small snags and holes smaller than 1/8 inch square (one ripstop box) located further than 10 inches (25.4cm) from the closest line attachment may be left unrepaired as long as there are no more than one in any 10-inch (25.4cm) circle.
  • A maximum of three such snags per cell are allowed.
  • Ripstop tape is not authorized for use on Performance Designs reserves. If the damage is enough to warrant a repair, a sewn repair must be done.
  • Minor repairs - Any hole or tear up to 10 inches (25.4cm) in length may be repaired by a senior rigger as long as the closest area of the completed repair is at least 1 inch (2.54 cm) from the nearest seam and at least 5 inches (12,7cm) from the nearest tape or line attachment.
  • Major repairs - Applies to any line, tape or webbing damage. Lines may be replaced by a master rigger. However, it is recommended that these repairs be done at the factory.
  • Master Riggers may perform repairs that do not involve taking apart any bartacks on the canopy. Special bartack patterns are used that are not normally found in the field. In addition, removal and replacement of these stitch patterns usually weakens the fabric to the point that it is necessary to replace portions of panels. The original templates are needed to complete this correctly.
  • All replacement materials and thread must come from the Performance Designs factory and: must have been purchased within 2 years have been stored properly show no signs of discoloration. Under strength thread and fabric is frequently found in the field. The only way to be sure your materials are up to Performance Designs standards is to purchase them directly from Performance Designs.

  • Rip-stop tape is not authorized for use on Performance Variable reserves. If the damage is enough to warrant a repair, a sewn repair must be done.
  • Any hole or tear up to 10" in length may be repaired by a senior rigger as long as the closest area of the completed repair is at least 1" from the nearest seam and at least 5" from the nearest tape or line attachment.
  • Any line damage is a major repair. Lines may be replaced by a master rigger. However, it is recommended that these repairs be sent back to the factory. All replacement lines must come from the Performance Variable factory.
  • Master riggers may perform any repairs that do not involve taking apart any bar-tacks on the canopy. Special bar-tack patterns are used that are not normally found in the field. In addition, removal and replacement of these stitch patterns usually weakens the fabric to the point that it is necessary to replace portions of panels. The original templates are needed to complete this correctly.
  • Reserves may only be repaired using certified materials. Under-strength thread and fabric is frequently found in the field. One way to be sure your materials are up to Performance Variable standards is to purchase them directly from Performance Variable.
