The Stroke Simulator must be able to pull both reserve ripcord pins positively and completely to ensure adequate travel of the AR2 power cable. Inadequate travel of the AR2 power cable may cause the parachute to not deploy, resulting in serious injury or death of the parachutist. 

If ripcord pins fail to pull completely, check the length of the reserve closing loop, the condition of the backing plate, power cable housing and routing of power cable assembly. 

## WARNING 

## NOTE 

1. Test routing and installation of the power cable assembly in the parachute harness/container while the harness/container is being worn in the normal fashion. 

2. Connect stroke simulator to power cable assembly in place of the AR2. 

3. Firmly hold stroke simulator adjacent to the AR2 pocket in a vertical orientation (i.e. stroke simulator plunger pointing down). 

4. With assistance from another individual, carefully attach a 33-pound weight to the stroke simulator plunger and very slowly remove your hand from under the weight to allow the weight to be slowly transferred to the stroke simulator. 

5. The weight must completely withdraw the ripcord pins within the available stroke. 

6. Maintain control of the reserve pilot chute in an effort to prevent the entire contents of the reserve parachute from falling to the floor. 

7. If the 33-pound weight hesitates or fails to pull the ripcord pins, remove and inspect the entire power cable assembly IAW this technical manual, WP 0047 00 and TM 10-1670-305-23&P, WP 0019 00. If unserviceable, replace with a new item from stock, then repeat Slack Checker Test and Stroke Simulator Test above. If the system fails a second time, it must be tagged and removed from service IAW WP 0011 00. 

8. Detach stroke simulator from power cable. 

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

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