Common use of Essential Unscheduled Maintenance Demand (EUMD) Clause in Contracts

Essential Unscheduled Maintenance Demand (EUMD). An unscheduled maintenance event resulting from an essential function failure or system abort. Fully redundant component failures, albeit do not cause the loss of a mission essential function due to redundancy, should be classified in this category since they are necessary for the system to be fully capable. An EFF that is corrected by the crew/operator (and authorized in the TM or other applicable document), generates both an EUMD and a CCMD.
