TEST
7-Pound Minimum Ripcord Pull Test
During the annual re-pack cycle for the MIRPS, a 7-pound ripcord pull test will be performed on each system
to ensure the integrity of the ripcord grip pocket as follows:
NOTE
To conduct the minimum 7-pound pull test, the packed MIRPS shall be
firmly attached by its two-connector snaps to a suitable rigid structure
such that the pack tray is positioned horizontally with the ripcord grip
pointing down. There must be sufficient clearance beneath the
horizontally suspended MIRPS to suspend a weight from the ripcord
grip and allow it to withdraw the ripcord grip.
1. Prior to unpacking the MIRPS for the annual re-pack cycle, carefully attach a 7-pound weight to the
ripcord grip and very slowly remove your hand from under the weight to allow the weight to be 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
from tilting. The weight must not completely withdraw the ripcord pins from the soft loops or the ripcord
completely from the pocket.
2. If the 7-pound weight causes complete withdrawal of the ripcord pins or the ripcord grip, then the ripcord
pocket is too loose and must be replaced IAW WP 0028 00.
3. If the MIRPS passes the 7-pound minimum ripcord pull test, repack the MIRPS IAW WP 0013 00.
4. 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).
