Care Of The Parachute; Inspection Of The Parachute; Packing The Parachute - NPI NATIONAL 360 Manual

CARE OF THE PARACHUTE

Parachutes are simultaneously very rugged and quite delicate. They are life saving pieces of
equipment and should be treated with care. Parachutes are made of nylon, a very strong and
durable material, but even nylon has enemies. Most acids will destroy nylon and ultra-violet
light from the sun weakens nylon over time. This is a surface effect so that the thicker
materials (webbing or pack fabric) are not seriously affected, but canopy cloth is very
vulnerable. If your National 360, 425 or 490 parachute is opened, avoid continued exposure
to direct sunlight. Grease and oil will not damage the nylon but can stick the canopy fabric
together, preventing it from functioning properly. Excessive moisture should be avoided; if the
canopy becomes wet or damp, it should be aired and repacked. If your National 360, 425 or
490 parachute is opened or used, it should be taken to a Certified Parachute Rigger,
Parachute Loft or returned to the Manufacturer, for inspection and repack.

INSPECTION OF THE PARACHUTE

Canopy Check: Inspect fabric for stains, cuts and tears. Check all stitching and accomplish
all repairs as per Mil-P-6645 or use best practice. Contact the Manufacturer if in doubt.
Pilot Chute: Inspect fabric and mesh for stains, cuts and tears. Check the spring for
damage. Inspect the pilot chute bridle for cuts or burns. Check stitching. Repair or replace
as required.
Harness: Check harness for cuts, abrasions, and excessive wear. Inspect all hardware for
proper function. Check all stitching.
Container: Inspect for cuts, holes and stains. Tears under one inch may be patched. Use
best practice. Damage to stiffeners or webbing shall be cause for assembly replacement.

PACKING THE PARACHUTE

The Federal Aviation Administration (USA) specifies that Emergency Parachutes are to be
repacked every 120 days* by a Certified Parachute Rigger that is properly rated for the type
of parachute to be packed. All necessary tools and equipment must be available in the
packing facility. After recording all pertinent data on the parachute, proceed to the following
packing steps.
*The repack cycle may vary in other countries; see "REPACK SCHEDULE" on previous page.
