How often must a transponder be inspected to comply with regulation?

The regulation mandates that transponders must be inspected every 24 months to ensure they are functioning correctly and in compliance with aviation standards. This inspection is crucial because transponders play a vital role in aircraft operations, especially in maintaining safe air traffic management. They provide essential information to air traffic controllers about an aircraft's identity, altitude, and location, which is critical for avoiding collisions and ensuring safe navigation. Regular inspections every 24 months help maintain the reliability and accuracy of these systems. Additionally, these periodic checks ensure that any potential issues are addressed before they can impact flight safety.
