Which record must be maintained for 12 CCM?

The correct answer pertains to the requirement for maintaining records of self-inspections for a period of 12 Continuous Compliance Monitoring (CCM). Self-inspections are crucial because they help ensure that the airport complies with safety, security, and operational standards set by regulatory authorities. Regular self-inspections demonstrate proactive management of airport safety protocols, contributing to the maintenance of an efficient operation.

Maintaining these records allows the airport to provide evidence of compliance during audits or inspections by authorities. This documentation can include findings, corrective actions taken, and timelines for implementing improvements, which are essential components of the CCM philosophy.

The other options, while pertaining to certain operational aspects of airport management, do not share the same specific requirement for a 12-month retention period as self-inspections, making that answer the most relevant in this context.
