3. Check the main deployment system, of which there are three basic types in use today. The first is a ripcord similar to the pilot emergency system. The second type is the throw-out pilot chute (TOP). The third is the pull-out pilot chute (POP). 

a. Next, inspect the main ripcord system. Check the ripcord and main pilot chute the same as with the pilot emergency system. Inspect the ripcord pocket for proper holding of the ripcord handle. 

b. For throw-out pilot chutes, inspect the pilot chute fabric and mesh for holes. Check the TOP handle at the top of the pilot chute for security, paying special attention to the tape holding the handle, which is particularly prone to wear. Check the bridle attachment to the pilot chute. If it is of a centerline collapsible design, check the centerline for wear and stretch and make sure the length of the bridle is correct. Check the curved locking pin for wear or damage as well as the tape, which attaches it to the bridle. [Figure 5-28]  Check the pilot chute pocket for fit and wear. Most of today’s installations are what is known as a “bottom of container” (BOC) configuration. It is particularly important that the elastic material from which the pocket is made is in good condition. A loose pocket can result in a premature deployment of the main parachute. 

c. If repacking a pull-out parachute, check the pilot chute and bridle in the same manner of the throw- out parachute inspection. Check the lanyard and handle for wear.

4. If Velcro $^{®}$ is used on the main pin protector flap, be sure to inspect its condition. If a plastic closing flap or tongue is used, check for deformation or breakage. [Figure 5-29]

5. If Velcro $^{®}$ is used on the main riser covers, be sure to check its condition. If plastic, check for breakage and deformation. If the plastic is excessively deformed, it is a sign that the covers do not fit properly and may open prematurely causing problems. 

6. For the container-closing loop, the same criteria applies as in the pilot emergency parachute. In addition, make sure the loop material is the same as specified in the owner’s manual, especially if an AAD is installed. With certain AADs, a particular type of knot and washer to be used is specified as well. 

## Ripcord 

All the areas mentioned in the pilot emergency parachute section apply to the sport rig. In addition, some assemblies utilize a ripcord that has a webbing loop handle or a pillow-type handle similar to the 3-Ring ® release handle. [Figure 5-30] It is important that the rigger check these handles for proper markings and fit to the assembly. Make sure that there is sufficient slack in the cable to allow no loading of the pin in any attitude or position that the wearer may conceivably get into. Most, if not all of these style handles, utilize Velcro$^{®}$ to secure them to the harness. Make sure the Velcro$^{®}$ is in good condition for holding ability but not so much as to inhibit the pull force. 

Remember, while both the pilot emergency parachute and sport piggyback assemblies share many areas in common, each has peculiar requirements for its use. It is important for the rigger to recognize these and handle each system accordingly.
