After complete reassembly of equipment, what must be performed?

After the complete reassembly of equipment, conducting an operational check is essential to ensure that the equipment functions correctly and meets the required specifications. This step is critical as it verifies that all components have been assembled properly and are operating as intended. An operational check helps identify any issues that may have arisen during the reassembly process, such as improper connections, misalignments, or components that may have been reinstalled incorrectly.

The operational check typically involves running the equipment through its normal operating procedures and monitoring its performance to ensure that all systems are responding appropriately. By performing this check, technicians can ensure reliability and safety in the equipment, which is particularly important in aviation where equipment performance can significantly impact flight safety.

While visual inspections, continuity tests, and calibrations are also important processes in maintenance and assembly, they serve different purposes. Visual inspections focus on identifying any obvious defects or issues, continuity tests check electrical connections, and calibration ensures that instruments are providing accurate measurements. An operational check, however, comprehensively assesses the overall functionality after reassembly, making it the most critical step in this scenario.
