SERVICE BULLETIN # SPSB: 03032000
SUBJECT: CLOSING LOOP RETAINER MODIFICATION
Javelin Harness and Container Assemblies: All Sizes manufactured
during August 1993 and earlier.
A small diameter suspension line got caught under the grommet on the main closing
loop retainer of a Javelin Harness and Container Assembly and resulted in a fatality.
The retainer in the main container pack tray of the above mentioned assemblies
is installed in such a way that the closing loop grommet
faces the main deployment bag when packed. Small diameter main canopy suspension
lines (similar to Microline 550 and Vectran 500) could get caught around the grommet
and may result in a reserve being deployed into a cutaway yet still
The grommet on the affected closing loop retainer should be shielded from any
interaction with the main canopy suspension lines, during stowage or
depoyment of the main canopy. The recommended method of
shielding the grommet is addressed in the attached pictures and explanation.
Before the next jump.

1. Existing closing loop retainer on rigs
manufactured prior to and including August 1993.
NOTE: This modification is to be carried out by
suitably qualified riggers.
CAUTION: BE CAREFUL NOT TO STITCH THROUGH ANYTHING BUT
THE CLOSING LOOP RETAINER ITSELF!
2. Fold exposed grommet on loop retainer back on itself (i.e. toward the
reserve container and get the folded over edge as close as
possible to the point of contact with the reserve).
Recommended tacking thread to be used is:
Waxed 5 cord, Super tack Type-1 - Size 2, Lite
Super Tack Type 1 - Size 3.
Begin hand tacking the closing loop retainer
from the inside of the fold over
(this is to end up with the knot on the hand tacking unexposed upon
completion) and make (5) five continuous looping stitches
from one side to the other. Refer to Figure 3 for the reverse view of the
3. Reverse side view of Figure 2.
Pull each revolution of hand tacking tight
to ensure a secure stitch pattern.
4. Continue with stitching pattern and return back to start
point completing a total of (9) nine looping stitches.
Both ends of the hand tacking thread should now
be on the same side of the closing loop retainer.
Remeber to end the last hand tack on the inside
of the fold over. Pull each revolution of hand tacking
tight to ensure a secure stitch pattern.
5. Reverse view of Figure 4.
6. Tie off both ends of thread with a surgeons knot (refer
to Poynter's Parachute Manual Volume 1).
7. Twist Ends of waxed thread together
and trim at 1 1/2 inch. Fold trimmed waxed ends
in between the layers of the Closing Loop Retainer.
8. Finished stitching view grommet side now
facing reserve container showing closing loop installed.
9. Finished stitching view of reverse side of Figure 8.
Refer to Figure 1 to ensure that the grommet
on the closing loop retainer now faces
in the opposite direction (i.e. toward the reserve container).
Modification to be recorded on the Reserve Packing Data Card as follows:
SPSB 001, Date, Rigger's Certificate Number and Signature
NOTE: Modification to be periodically inspected.
After completing the modification, the closing loop length
will need to be adjusted to compensate for the
shortening of the closing loop retainer.
