Why is it important for QA to monitor chafing?

The importance of monitoring chafing primarily revolves around the prevention of potential wiring failures. Chafing occurs when wires or cables rub against other surfaces, which can lead to insulation wear and, subsequently, electrical shorts or failures. Monitoring chafing is critical because damaged wiring can pose serious safety risks during flight operations, including malfunctions of vital electrical systems or even fire hazards.

By detecting and addressing chafing early, quality assurance personnel can ensure that the wiring remains intact and functions properly, ultimately safeguarding the integrity of the aircraft’s systems. Other aspects, such as compliance with standards or repair times, may be relevant but do not directly address the critical safety issues associated with wiring failures stemming from chafing.
