Which of the following actions should NOT be taken with equipment?

Tampering with equipment is an action that should not be taken because it compromises safety and integrity. Maintaining the proper functioning of aviation equipment is crucial for the safety of all involved in aviation operations. When equipment is tampered with, it can lead to malfunctions or failures, endangering pilots, passengers, and crew.

In contrast, displaying irregular operating status information, reporting malfunctions, and regularly testing equipment are all essential practices that promote safety and ensure that equipment is functioning correctly. These actions contribute to the overall maintenance and reliability of aviation systems, ensuring that any issues are detected and addressed promptly. By adhering to safety protocols and maintenance practices, the likelihood of accidents and equipment failures is significantly reduced.
