MRCs are the working documents for squadron aircraft and equipment inspections and preventive maintenance actions. These 5- by 8-inch cards specify the tasks that relate to a particular system, subsystem, area, or component and state a logical sequence to accomplish the tasks. MRCs identify the recommended rating that is needed to perform the task, the performance interval, and the work area or the work zone involved. Assembled into sets and numbered in sequence, the cards contain pertinent information that maintenance personnel require to complete each task. Data for each task includes the following information: description; approximate time that is required to perform the task; whether power, tools, equipment, or material is needed; and information on such items as pressures and torque values. Also included, when necessary, is a diagram of the affected area in which the work is to be accomplished. A master file copy of current MRCs should be maintained within the maintenance department. This master file copy reflects revisions to the published card sets and additional local requirements. Local periodic maintenance requirements for equipment that is not covered by published MRC sets should be added as specified in the NAMP. When an aircraft undergoes an inspection, MRCs are given to the maintenance person in the specified order of the cards. Certification of completion of the work is not made on the MRC cards; therefore, the cards are used until they are worn out. Before a set of cards is issued, the check crew supervisor should check each card against the master file set to ensure that the set of cards is complete and current. Periodic Maintenance Information Cards Periodic maintenance information cards (fig. 4-2) are decks of cards that refer to the maintenance of aeronautical equipment and aircraft. The cards support maintenance actions and cite, when necessary, requirements for documentation and operating limits. PMIC decks contain the following information: Requirements for items that have approved mandatory removal and replacement intervals as well as requirements that require special monitoring with emphasis on failure trends. The card cites the component or assembly removal and replacement schedule, Equipment History Record (EHR), Scheduled Removal Component (SRC) card; Assembly Service Record (ASR), or Module Service Record (MSR) that contains the requirement. Airframe structural life limits. Maintenance requirements system index that lists, by Work Unit Code (WUC), the system and the MRC number of the requirement to be performed. Conditional inspection listing that contains a brief description of the condition, type inspections to be performed, and a reference to the manual or directive that contains the detailed requirements. Phase change implementation card that provides a list of requirements to be performed to maintain the required inspection interval of critical components when an update changes the order of inspections. NOTE: NALCOMIS OMA allows users to input, update, and delete maintenance requirement card information for special, phase, and conditional aircraft and engine inspections. This information provides pertinent information that is required to print inspection control and look phase MAFs. The QA work center verifies that MRC information is added or updated in the NALCOMIS database as changes occur to MRC decks. Sequence Control Cards (SCCs) Sequence control cards (SCCs) are graphic, sequential work displays. They help ensure the orderly planning and timely performance of aircraft and engine maintenance requirements. SCCs integrate all required periodic maintenance work to reduce the total out-of-service time that is required to complete unscheduled and scheduled maintenance jobs. SCCs are used to control the assignment of work and personnel. SCCs provide the following information: Specific MRCs to be complied with Number of personnel and rating specialty that are required to complete the tasks Estimated task completion times Whether POWER/AIR OFF or ON conditions are required during tasks Affected areas where work will be performed 4-4
