How often should EMI gaskets be inspected for moisture intrusion?

The correct choice emphasizes the importance of regular inspection of EMI gaskets for moisture intrusion based on their usage. EMI gaskets play a critical role in preventing electromagnetic interference and moisture penetration, which can lead to corrosion and affect the performance of avionics systems.

Regular inspections allow for the timely detection of any deterioration or failure of the gaskets, particularly in environments where exposure to moisture is more likely or operational demands are high. This proactive approach ensures that any issues can be addressed before they escalate, maintaining the integrity of the protective barrier that gaskets provide.

By tailoring the inspection frequency to the specific usage and environmental conditions, maintenance personnel can implement an effective corrosion control strategy, thus enhancing the reliability and longevity of the avionics equipment.
