PD Reserves: After 40 repacks or 25 deployments have been reached, the reserve must have its permeability tested. (In most
countries, 40 repacks are usually performed over a 10 to 20 year period.) The testing is performed to insure that
the fabric permeability has not reached a point where the openings and landing performance would be unacceptable.
Subsequent to passing this testing, an additional label is affixed and the canopy is then returned into service.
The label will contain additional boxes, the specific number being chosen according to the results of the test. Mike "Hike" Levandier
