If a discrepancy exists between the procedures in Publication 123 and the MEL, which procedures must be followed?

• A. Publication 123
• B. MEL
• C. Both
• D. Neither

Answer: (B)

When a discrepancy exists, the MEL is the procedures to follow. The MEL (Minimum Equipment List) is an authority-approved document that specifies what equipment may be inoperative and lays out the exact actions and limitations for operating the aircraft with that inoperative equipment. Because it is aircraft-specific and carries regulatory approval, it takes precedence over standard operating procedures found in Publication 123. Publication 123 provides normal, non-restricted procedures, but it can’t override the validated limits and corrective actions defined in the MEL. If a conflict arises, you must follow the MEL to maintain airworthiness and regulatory compliance, and only perform Publication 123 procedures to the extent they are consistent with the MEL.
