REMOVAL OF BALLISTIC
SPREADING GUN
Before you work on a spreader gun, always
ensure that a safety pin is installed. If you have
to remove a damaged or defective spreading gun,
proceed as follows:
1. Loosen the screws holding the plates to the
spreading gun slugs to allow suspension lines to
be removed.
2. Slip all the suspension lines and attached
loops from under the plates.
3. Disconnect the retaining cord from the vent
lines.
4. Tie one end of a temporary 20-foot line to
the vent lines, and tie its other end to the free end
of the retaining cord.
5. Pull the retaining cord out of the canopy
from the skirt end.
6. Untie the temporary 20-foot line from the
retaining cord, and remove the damaged or
defective gun from the table.
7. To install a new or repaired spreading gun,
follow the procedures outlined in the applicable
parachute assembly chapter in the Emergency
Personnel and Drogue Parachute Systems
Manual, NAVAIR 13-1-6.2.
