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.
