emergency use”.  The continued airworthiness of an assembly is at the discretion of the FAA licensed parachute 
rigger’s inspection during repack.  While proper care can no doubt extend its usefulness, an older parachute 
should be examined more closely for signs of deterioration.  Your parachute is a sensitive piece of life saving 
equipment and should be treated as such.  However, it should not be expected to last forever, even with proper 
care.

1.9 Preflight Inspection

The parachute must be inspected by the wearer prior to each use.  Check it visually for any unsafe 
condition.  Be sure the harness is not twisted or misrouted.  Be sure the fittings are not rusted. 
Be sure the ripcord handle is securely in its pocket (under the fabric pocket covering).  Unzip the 
cushion and check the ripcord pins.  Be sure they are properly seated in their loops.  All pins should 
extend at least 1/2-inch beyond the fabric locking loop.  Be sure the rigger’s seal and thread are still 
intact around the furthest pin.  That is your assurance it has not been opened since it left the rigger’s 
packing table.  Check the packing data card in the nearby pocket to be sure that the parachute is 
current and has been repacked in accordance with regulations.

1.10 Fitting the Parachute Harness

Strong Enterprises produces 3 basic harness designs: the standard fixed harness, the fully adjustable 
harness, and the aerobatic harness.  Below, please find proper fitting for each of these models.

Standard Fixed Harness - This harness has 3 adjustment points, one on the chest, and one on 
each leg.  If you are putting the parachute on for the first time, unsnap the hardware on the straps, 
loosen the three adjustment points, and slip your arms through the main lift web (the vertical straps 
in front), much like putting on a jacket.  Next, reach between your legs, pick up each leg strap, 
untwist them if necessary, and snap them in place on each side of the lower portion of the main lift 
webs.  Lean forward, pull the leg straps below your hips, and tighten them snugly, yet comfortably 
around your thighs.  Finally, snap and adjust the chest strap.  Fold and stow the webbing ends in 
the elastic keepers.  Be sure the ripcord handle is securely stowed, yet accessible.

Fully Adjustable Harness - The fully adjustable harness allows you to custom fit your harness. 

 

To properly adjust this harness, first loosen all adjustment points all the way out.  Then put on the 
parachute as explained above being sure to fit the leg straps snugly.  Then stand at attention and 
take up the slack in the main lift web (vertical straps) by pulling on the harness ends located just 
above the leg pads.  This should pull the straps down snug over your shoulders.  Next adjust the 
horizontal back strap (located behind you at the leg junction) to come in contact with your back.  
This strap need not be tight for a comfortable fit.  Finally, snap and adjust the chest strap, fold and 
stow the webbing ends in the elastic keepers.  Be sure the ripcord handle is securely stowed, yet 
accessible.

Aerobatic Harness - The Aerobatic, or two-point harness moves the snaps normally located on the leg, to the 
middle of the chest, thereby preventing interference with your seat belt.  To properly don this harness, loosen 
the two adjusters all the way out.  Slip your arms through the main lift webs (the vertical straps in front), much 
like putting on a jacket.  Then reach between your legs, pick up the right leg strap, untwist if necessary and 
thread the right strap through the loop located on the right main lift web at the leg junction.  Take care not to 
twist the strap.  Next, snap it in place at the chest on the opposite (Left) main lift web.  Repeat the process for 
the left strap.  The straps should be adjusted tight, but not so tight that it restricts your ability to stand upright.  
Resist the urge to over tighten the straps once you are seated.  Fold and stow the webbing ends in the elastic 
keepers.  Be sure the ripcord handle is securely stowed, yet accessible.
