What information is recorded in block 3 of the Preflight/Daily/Turnaround/Postflight Maintenance Record?

Block 3 of the Preflight/Daily/Turnaround/Postflight Maintenance Record is designated for recording the T/M/S, which stands for Type/Model/Series of the aircraft. This is an important detail as it specifies the exact model of the aircraft being maintained, allowing for accurate tracking of maintenance history and compliance with specific operational and maintenance requirements. Knowing the T/M/S helps maintenance personnel ensure that they are referencing the appropriate technical manuals, procedures, and parts specific to that aircraft type, which is crucial for efficient and safe maintenance operations.

The other options, while important in their own contexts, are recorded elsewhere in the maintenance documentation. The type of inspection is categorized in other blocks, discrepancies or Job Control Numbers (JCN) are captured in designated sections regarding specific maintenance issues, and tool container numbers are tracked separately to ensure accountability of tools used during maintenance. These elements all contribute to comprehensive maintenance tracking, but block 3 specifically focuses on identifying the aircraft type.
