Ripcord Maintenance Checklist: Inspect, Replace, and Stay SafeA ripcord is a small but critical component in many safety systems—most famously in parachutes, but also in seatbelts, emergency egress systems, and specialized rescue equipment. Regular maintenance and inspection of ripcords ensures that when you depend on them, they work without fail. This checklist explains how ripcords function, what to look for during inspection, when to replace them, and safety best practices to minimize risk.
What a Ripcord Is and Where It’s Used
A ripcord is typically a cord, cable, or handle mechanism designed to release or deploy a safety device when pulled. Common uses include:
- Parachute deployment (skydiving, military parachutes)
- Emergency evacuation handles (aircraft, trains)
- Rescue equipment and survival kits
- Mechanical safety releases and seatbelt cutters
Key point: A ripcord’s reliability depends on material quality, correct installation, and regular maintenance.
Materials and Common Designs
Ripcords come in several materials and designs:
- Braided nylon or polyester cords (durable, flexible)
- High-strength synthetic lines (e.g., Dyneema, Spectra)
- Stainless steel cable (used in high-load mechanical systems)
- Handles with molded grips, sometimes with protective covers or pins
Designs vary from simple pull cords to integrated mechanisms with locking pins, shear pins, or breakaway features. Know the specific design and manufacturer guidelines for the ripcord you’re inspecting.
Tools and Supplies You’ll Need
- Bright inspection light and magnifying loupe (for close inspection)
- Clean, lint-free cloths
- Mild soap solution and water (or manufacturer-approved cleaner)
- Corrosion inhibitor (for metal parts), silicone-free lubricant (if allowed)
- Replacement cords, pins, or handles (manufacturer-specified)
- Torque wrench or basic hand tools (for assemblies)
- Inspection log or checklist form
Pre-Inspection Safety Steps
- Ensure the system is in a safe state for inspection (disarmed, grounded, or otherwise rendered non-operational).
- Follow lockout/tagout procedures where applicable.
- Wear appropriate PPE—gloves, safety glasses, and any other gear required for the equipment.
Visual Inspection Checklist
Inspect visually under good lighting, using magnification where needed:
- Cord condition: Look for fraying, broken fibers, thinning, kinks, or localized wear.
- Discoloration: UV fading, chemical staining, or heat damage signals weakened material.
- Handles and grips: Check for cracks, deformation, or broken attachments.
- Stitching and terminations: Inspect splices, knots, whipping, and stitched terminations for integrity.
- Metal parts: Examine ferrules, crimps, pins, and cable ends for corrosion, cracks, or deformation.
- Protective covers: Ensure sheaths, boots, or guards are intact and secure.
- Mounting hardware: Check for loose bolts, worn housings, or misalignment.
- Accessibility: Verify the ripcord is unobstructed and the pull path is clear.
Quick-fail indicators: Any exposed broken fibers, cracked handle, significant corrosion, or missing safety pin/retaining clip.
Functional Tests
Where allowed and safe, perform functional checks:
- Smoothness of pull: The cord should move freely without snags.
- Activation test: In non-critical systems or with a safe test setup, confirm the ripcord releases the mechanism.
- Return/reset: Verify the mechanism can be properly reset following manufacturer procedures.
- Tactile feedback: Ensure the handle provides expected resistance and release feel.
Always follow manufacturer instructions and avoid live-system tests that could endanger personnel or equipment.
When to Clean and How
- Clean ripcords when contaminated with dirt, salt, oil, or chemicals.
- Use a mild soap and water solution for textile cords; rinse thoroughly and air dry away from direct heat or sunlight.
- For metal components, remove corrosion with a soft brush and apply a light corrosion inhibitor as recommended.
- Do not use solvents, bleach, or petroleum-based cleaners on synthetic cords unless manufacturer permits.
Replacement Criteria
Replace ripcord components if any of the following are present:
- Visible fraying, broken fibers, or significant thinning
- Damage from heat, chemical exposure, or UV degradation
- Corrosion or deformation of metal elements affecting strength
- Cracked, deformed, or loose handles and terminations
- Failed functional test or inability to reset the system properly
- Ripcord exceeds manufacturer’s service life or scheduled replacement interval
If in doubt, replace. The cost of a new ripcord is negligible compared to the risk of failure.
Recordkeeping and Inspection Intervals
- Log every inspection, cleaning, test, and replacement with date, inspector name, findings, and actions taken.
- Follow manufacturer-recommended inspection intervals; if unavailable, adopt a conservative schedule:
- High-use or harsh environments: weekly to monthly inspections
- Moderate-use: monthly to quarterly
- Low-use or stored equipment: before each use and quarterly inspections
- Include ripcord checks in broader pre-use or safety inspection routines.
Storage and Handling Best Practices
- Store cords away from direct sunlight, extreme heat, and chemicals.
- Keep in dry, ventilated spaces; avoid contact with oils, fuels, or solvents.
- Coil textile cords loosely—avoid tight bends or kinks that create stress points.
- Protect detachable handles and pins in labeled containers to prevent loss or damage.
Training and Human Factors
- Train all users on correct grip, pull technique, and emergency procedures.
- Emphasize clear labeling and visibility of ripcord handles (bright colors, reflective tape).
- Conduct periodic drills to ensure familiarity without stressing equipment unnecessarily.
- Encourage reporting of any noticed abnormalities immediately.
Special Considerations for Parachute Ripcords
- Parachute ripcords are subject to strict manufacturer and regulatory standards; always defer to those instructions.
- Reserve live deployment tests for certified rigger facilities.
- Pay extra attention to packed deployment bags, pilot chutes, and container interfaces where ripcord interaction occurs.
Emergency Replacement Kits
Keep a small kit with:
- Manufacturer-approved replacement cord or cable
- Spare handle and retaining pins
- Ferrules, crimps, and basic tools
- Instruction sheet for emergency replacement steps
Use emergency replacements only as temporary fixes until a full, certified replacement/repair can be performed.
Troubleshooting Common Issues
- Stiff pull: Check for foreign debris in the housing; inspect for corrosion or bent guides.
- Intermittent release: Inspect for partial frays, kinks, or misrouted cord; test activation under controlled conditions.
- Handle wiggle or looseness: Replace handle or tighten mounting; inspect for cracked housings.
Final Safety Reminders
- Never jury-rig or splice a ripcord with non-approved materials.
- Replace components rather than attempting questionable repairs.
- When life-safety equipment is involved, err on the side of conservative action—replace, document, retest.

- Convert this into a printable checklist sheet,
- Create a short inspection log template,
- Or tailor the checklist to a specific ripcord type (parachute, aircraft egress, rescue kit).
