Multiple possibilities concerning the layout and functionality of the Maintenance Control Centre (MCC) are possible depending on the organisations’ size, scope and objective. To work as an independent unit or integrated within the CAMO Basic Functionality. (Note Basic Functionality is Planning – Engineering – Reliability – Technical Records)

MCC sits between the Operators – Operations Control Centre (OCC) and the Aircraft Maintenance Organisation (AMO).

The Maintenance Control Centre usually works side by side with:
