If the 7-pound weight causes complete withdrawal of the ripcord pins or the ripcord grip, then
remove the pack tray and ripcord grip from service.
If the pack tray and ripcord grip are new (part of a MIRPS assembly), or a new replacement pack
tray, submit a standard Form (SF) 368, Product Quality Deficiency Report (PQDR) for the new
If the pack tray is used and a new MIRPS ripcord grip pocket was applied, verify the application
procedures in WP 0028 00. If applied correctly, submit a PQDR for the new ripcord grip pocket
and ripcord grip.
12. Conduct a 27-Pound Maximum Ripcord Pull Test on the T-10R and the MIRPS as follows:
While standing to the left or right side of the T-10R or MIRPS, carefully attach a 27-pound weight
to the ripcord grip and very slowly remove your hands from under the weight to allow the weight
to be very slowly transferred to the ripcord grip. Do not release the weight suddenly or let it drop
since this will invalidate the test.
The weight must be evenly distributed around or centered on the ripcord grip to prevent the grip
The 27-pound weight must withdraw the ripcord pins from either the pack release cones or the
soft loops and the ripcord grip from the pocket.
If the 27-pound weight does not withdraw the ripcord grip and pins, then remove the weight and
re-inspect the ripcord pins, pack releasing cones, and the ripcord pocket to ensure there are no
bent pins and ensure proper alignment of the pinholes in the pack releasing cones. Bent pins or
misaligned holes can significantly increase the ripcord withdrawal force.
If the ripcord pins, cone holes and pocket are serviceable, carefully remove the ripcord pins and
at the same time, insert temporary pins to keep the pack tray closed. Leave the ripcord grip in
Do not rotate the grip completely around (360) within the pocket as
this may damage the ripcord pocket.
If the pack tray is used and a new T-10R or MIRPS ripcord grip pocket was applied, verify the
application procedures in WP 0028 00. If applied correctly, submit a PQDR for the new ripcord
grip pocket and ripcord grip.
If the MIRPS passes the 7-pound minimum and the T-10R and the MIRPS passes the 27-pound
maximum ripcord pull test, repack the T-10R IAW WP 0012 00 and the MIRPS IAW WP 0013
Annotate completion of this test (test conducted, name of tester, date completed) on the notes
page of the parachute log record book (DA Form 3912), or applicable location in the
NAVWPNCEN or NAVWPNS CL 13512/11 (Parachute History Record).
