Communication Cord

1. Visual Inspection

• Check the entire length of the communication cord for cuts, fraying, or exposed wiring.
• Inspect the connectors for bent, corroded, or missing pins that could affect performance.
• Ensure the cord’s outer sheath is intact and free of cracks or excessive wear.
• Look for kinks, twists, or knots that could impact signal transmission or durability. Pay special attention to any areas with after market attachments, bundling or hardware

2. Connection & Fit Check

• Securely plug the communication cord into the aircraft’s audio port and ensure a snug fit.
• Connect the cord to the external communication system and check for loose or unstable connections.
• Verify that all strain points (near connectors) for signs of excessive bending or stress. Pay special attention to where flexible cords are entering hard casings.
  

3. Functional Test

• Conduct a communication check by transmitting and receiving audio to confirm clarity and functionality.
• Listen for static, interference, or dropouts that may indicate internal wire damage or poor connections.
• Move and flex the cord gently and turn your head side to side while testing audio to detect intermittent connection issues.
• Test push-to-talk (PTT) functionality, if applicable, to ensure smooth and responsive operation.
