If an item is INOP and not listed in the Minimum Equipment List (MEL), what is the first step?

When an item is inoperative (INOP) and does not appear in the Minimum Equipment List (MEL), the appropriate first step is to contact Dispatch and speak to Maintenance. This is essential because the MEL provides specific guidance on what equipment can be inoperative for the aircraft to safely conduct flight operations. If a part is not listed in the MEL, it may indicate that its absence could significantly affect the safety or legality of the flight, thus requiring a thorough assessment by qualified personnel.

In this scenario, reaching out to Dispatch allows for a coordinated response that may involve consultation with Maintenance personnel who can evaluate the impact of the inoperative item and provide guidance on whether the flight can proceed or if other measures need to be taken, such as grounding the aircraft or arranging for repairs. This process ensures adherence to safety protocols and regulatory requirements, which help maintain the highest safety standards in aviation operations.
