Definition

A Maintenance Control Centre (MCC) is the central control and data collection point for maintenance at an airline or other aircraft operator.

Description

At most airlines, the MCC operates 24 hours a day to track maintenance discrepancies and inspection status of all aircraft. Other operators, such as companies with large business aviation fleets, might also set up a 24-hour MCC.

The MCC's duties include taking calls from flight crews to record maintenance problems and to assign mechanics to address those problems. If the maintenance issue is minor, the MCC can instruct the flight crew on the proper corrective action and documentation of that corrective action in the aircraft's maintenance logbook. For example, a simple reset of a malfunctioning component might involve pulling a circuit breaker, waiting for a specified time, and then resetting the breaker.
