    3. GENERAL The airplane is equipped with a Cirrus Airplane Parachute System (CAPS) designed to bring the aircraft and its occupants to the ground in the event of a life-threatening emergency. CAPS consists of a parachute, a solid-propellant rocket to deploy the parachute, a rocket activation sys- tem, and a harness imbedded within the fuselage structure.

  • Page 14: Incremental Bridle And Deployment Bag

    The CAPS parachute is fabricated from woven textiles in the form of fabrics, tapes, webbing, and thread. All of the textile components in CAPS are fabricated from either Kevlar or Nylon and are woven to military specifications that define specific parameters such as yarn count, yarn twist, weave type, and finish.

    Exercise caution when sanding composite surface to prevent sanding into laminate. Control dust migration. Using die grinder and disc, at CAPS cover edge-seam reference mark, sand in a 0.5 inch (1.3 cm) area, and locate CAPS cover seam line. Sand around cover circumference follow- ing seam line to reveal entire perimeter of cover.
  • Page 24 Using die grinder and sanding disc, remove all remnant adhesive from fuselage flange, burnish lightening protection mesh, and abrade flange surface for adhesive application. Draw an offset line 0.25 inch (0.64 cm) from scribeline on new CAPS cover, and trim to off- set line to facilitate trimming and fitting.
  • Page 25 Note: To prevent cover deformation and generation of air pockets in adhesive, tape CAPS cover to fuselage with two people working on either side of air- plane. For RH and LH sides, cut 10, two-foot strips of filament tape and make ready for quick-use by lightly hanging each piece to the leading edge of horizontal stabilizer.
