SAFETY BULLETIN
National Parachutes
BACKGROUND
It has come to our attention that some pilots are incorrectly adjusting the
harness on National
back style parachutes resulting in the chest strap riding high under the
pilot's chin where in the event of a bailout there may be a risk of serious
injury or death when the canopy opens.
Some pilots are apparently using the floating harness Velcro to tighten the
leg straps because the leg strap adjustment buckle/thread though adapter
has disappeared under the leg pad cushion. They are stepping through the
leg loops and never undoing the leg straps at the Thread Through adapter on
parachutes with the Thread Through type leg strap connector.
This may also be happening with parachutes equipped with B12 snaps or Quick
Ejectors(QE's)
ACTION
The correct donning procedure including a diagram is described on pages 8,9
and 10 of the manual that accompanies the parachute.
Note that National Parachutes have a "floating" harness with a Velcro
adjustment where the Main Lift Web crosses the Side Strap. This adjustment
allows for different torso lengths, it is NOT, REPEAT NOT, so that you may
tighten the leg straps without using the leg strap adjustments.
In normal use the Velcro adjustment is adjusted for the individual pilot
and will not need changing unless a pilot with a different torso length
uses the parachute.
Once the Velcro adjustment has been made for that pilot the correct donning
procedure is as follows:
Put shoulders through shoulder yokes.
Fasten chest strap.
Bring leg straps around thighs, thread them through the adapters or if
harness is equipped with snaps, hook snap up with V-ring adapter and pull
to remove slack.
Stand up and move leg pads to desired position and tighten leg straps.
Tuck leg strap ends into leg pad cushion.
-------------------------------
Note it is a CHEST strap not a THROAT strap.
Note the "THREAD THROUGH" leg strap adapters are not designated "STEP
THROUGH".
