inspections. You will find more detailed information concerning automatic parachute ripcord release assemblies in the Emergency Personnel and Drogue Parachute Systems Manual, NAVAIR 13-1-6.2, and the Maintenance Requirements Cards, NAVAIR 13-600-4-6-3. MAINTENANCE Maintenance on any automatic ripcord release in service must be performed each time its parachute assembly is repacked. Maintenance consists of the following: . Disarming . Inspection . Firing altitude check . Arming and assembly . Checkout of armed mechanism As you work on a automatic ripcord release assembly, you are required to per- form several different types of maintenance and inspections. You are required to in- spect the operational condition of the auto- matic ripcord release before installing it in a parachute assembly. If you find any damage or an inspection discrepancy, submit a quality deficiency report, as discussed in OPNAVINST 4790.2 (series). NOTE: Under no circumstances should an unsatisfactory ripcord release be in- stalled. The first step in performing the normal inspection and maintenance on a automatic ripcord release is to disarm it. Then you are ready to inspect and perform the firing altitude checks. DISARMING Anytime you are required to disarm a ripcord release assembly, follow the procedures outlined in NAVAIR-13-1-6.2. The discussion that follows closely parallels those procedures. A parts breakdown can be seen in figure 2-1. NOTE: To remove the arming cable housing from the ripcord release, de- press the safety retainer release (fig. 2-1). NEVER try to remove the arming cable from an armed ripcord release assembly by pulling on the cable. This fires the auto- matic ripcord release. 1. Open the ripcord release pocket, and remove the ripcord release only a sufficient distance to allow disassembly. 2. Remove the locking screw and washer. NOTE: The cover and power cable housing assembly and the receiver and barrel assembly are serialized matched sets. Do not mix these assemblies. 3. Slide the cover off the receiver and barrel assembly. 4. Disengage the barrel snap lock. A close-up of this operation is shown in figure 2-2. 5. Remove the cartridge from the barrel as- sembly (fig. 2-1). Do not proceed until the quality assurance inspector (QA) has verified this step. 6. Remove the ripcord release assembly and the arming cable housing from the parachute container. Figure 2-2.—Disengaging barrel snap lock. 2-3
