ARMING AND ASSEMBLING THE AUTOMATIC PARACHUTE RIPCORD RELEASE

WARNING AFTER TEST FIRING, YOU MUST NOT USE A METAL TOOL TO PUSH THE HAMMER AND LOCK AS- SEMBLY BACK FROM THE FIRING WALL. TAKE EXTREME CARE TO AVOID SCRATCHING OR ABRADING THE POLISHED SURFACE OF THE LOCK. THE PURPOSE OF THE LOCK ASSEMBLY IS TO MATE WITH THE ANEROID SEAR AND INITIATE FIR- ING AT A PRESCRIBED ALTITUDE. A ROUGH OR SCRATCHED LOCK- ING ASSEMBLY MAY CAUSE A HANGUP DURING THE UNLOCKING FUNCTION. NOTE: Ripcord release assemblies with part number 711-07022-30 (10,000-foot) must fire at 10,000 feet (plus or minus 1,000 feet) pressure altitude. Ripcord release as- semblies with part number 711-07022-34 (14,000-foot) must fire at 14,000 feet (plus or minus 1,000 feet) pressure altitude. 10. Three firing altitude checks must be made. Any ripcord release that does not meet test requirements on all three checks will be rejected. Adjustments are not to be made. 11. Remove the dummy cartridge and inspect it for an indentation caused by the hammer firing pin striking the cartridge. This dent must be visible to the QA performing the inspection. ARMING AND ASSEMBLING THE AUTOMATIC PARACHUTE RIPCORD RELEASE The following instructions are the same type you will follow in the shop when arming and assembling the Model 7000 ripcord release. When you use the NAVAIR 13-1-6.2 manual and come to a step that is followed by “(QA),” that step must be inspected by a QA. 1. To arm the ripcord release that is installed in a parachute, your first step is to insert the arming cable housing through the holes in the parachute container and ripcord release pocket. 2. Next, feed the arming cable through the arming cable housing. Depending on application, the arming cable may be inserted at either side of receiver and barrel assembly (fig. 2-11). Figure 2-11.—Installing an arming cable. Figure 2-12.-Installing an arming cable housing. 3. With the ripcord release barrel in the open position, install the arming pin into the ripcord release. The pin must pass through the hole in the side of the receiver, through the firing mechanism lock, and out the opposite side of the receiver. 4. Next, you connect the arming cable housing to the receiver and barrel assembly. Ensure the safety retainer secures the housing to the receiver (fig. 2-12). Be sure that you check the cartridge service life at this time. You should not install a cartridge that will expire prior to the next scheduled repack of the assembly. Refer to NAVAIR 11-100-1 for the service/total life of cartridges. 2-7
