What information must be reported to Dispatch when reporting a maintenance discrepancy?

When reporting a maintenance discrepancy to Dispatch, it is crucial to include the tail number and a detailed description of the discrepancy. The tail number uniquely identifies the aircraft, enabling Dispatch to track and manage the specific maintenance issues associated with that aircraft effectively. The description of the discrepancy provides essential information about the nature of the problem, which helps in determining the appropriate course of action for repairs and maintenance scheduling. This detailed reporting ensures that all relevant personnel are informed and can take the necessary steps to address the issue promptly.

Other options, while they may be useful in specific contexts, do not encompass the critical information required for assessing and resolving maintenance issues as directly as the tail number and discrepancy details do.
