What does block 5 of the Preflight/Daily/Turnaround/Postflight Maintenance Record record?

Block 5 of the Preflight/Daily/Turnaround/Postflight Maintenance Record is designated for the side number of the aircraft being inspected. This information is essential for accurately identifying the specific aircraft in maintenance records, as each aircraft has a unique side number. This enables maintenance personnel to track and manage inspections, repairs, and discrepancies associated with that particular aircraft throughout its operational life.

Having the side number clearly recorded aids in maintaining aviation safety, accountability, and adherence to maintenance schedules. It ensures that all data logged in the maintenance record corresponds to the correct aircraft, which is crucial for effective fleet management and operational readiness.
