Your
PV
reserve must be inspected thoroughly before it is assembled and at every
repack. This inspection should be performed with even more care and attention when
first assembled and after a deployment.
An FAA-certified rigger must inspect your new
PV
reserve and determine its compatibility
with your rig.
Here is the
PV
recommended procedure for inspecting your reserve canopy. Consult the
owner’s manual and the Maintenance and Inspection Manual for your rig and other
components for instructions on inspecting them.
The permeability of the fabric is very important. As the permeability increases, the
canopy will open more slowly and flight performance will deteriorate. The rate of descent
will increase and the forward speed will decrease. The ability of the canopy to flare to a
soft landing will decrease.
To insure the canopy remains in compliance with TSO requirements and to insure the
canopy is safe to use,
PV
has established an average permeability limit of 6cfm for the
top and bottom fabric.
Fabric permeability does not change while the canopy is packed. It changes as a result
of use and handling. That’s why it’s important to maintain a complete history of the
parachute.
Fabric permeability must be tested if any of the following events occur:
♦
The canopy is completely submerged in water.
♦
25 jumps have been made on the canopy since it was new or last certified.
♦
The canopy has been repacked 40 times since it was new.
♦
Flight performance appears to be substandard.
♦
There are other reasons to believe the fabric porosity may exceed specifications.
The Performance Variable factory is equipped to perform permeability testing. It is
recommended that any canopy needing such testing be returned to the factory.
