The following ripcord pull test and the stroke simulator test are performed on all MC-4 systems each time the main parachute is initially placed in service and when the main closing loop is replaced. 

## NOTE

It is not necessary to start the pack process over again if the same initial packer is conducting the Ripcord Pull Tests. If a different Parachute Rigger has taken over any of the tasks associated with the Ripcord Pull Tests, then a complete re-pack of the main parachute is required. 

Re-closing the container after the ripcord pull test does not constitute a repack toward the normal repack cycle (120-days).
