MR is a part of the MDS; however, the primary responsibilities for the detailed procedures that are involved in MR are NOT the direct responsibility of the AZ. Therefore, MR will not be discussed further. Q2.    What reporting system is used to report all supply actions that support aircraft maintenance? MAINTENANCE DATA REPORTING (MDR) LEARNING OBJECTIVES: Define the purpose of Maintenance Data Reporting. Identify the purpose of various Maintenance Data Reports. Identify the purpose of selected NALCOMIS reports. MDR deals with the most complex and the widest range of data in the MDS. Maintenance data is generated at the most basic level—from the mechanic or technician who performs the maintenance task. Source documents that are used in maintenance data reporting include the MAF and the Metrology Equipment Recall (METER) card. By using coded information that is documented on these source documents, the local DSF compiles maintenance and material data reports. Aircraft maintenance workers use source documents to report the following information: What equipment was worked on (which system, subsystem, or component) What caused the failure or malfunction When the failure or malfunction was discovered What action was taken to repair the equipment What parts were used to repair the equipment The number of man-hours that were expended in repair The identity of the work center or work centers that did the work Once this information is compiled in a useable format (for example, monthly maintenance summaries), maintenance managers can use the information to manage aircraft maintenance organizations. MAINTENANCE DATA REPORTS Maintenance technicians at the local level generate large amounts of maintenance data. This data consists This MAF copy 1 DAR is prepared from data that was submitted on MAFs and is compiled in three parts. Part I and Part II are shown in figure 5-1. Part I contains data that have no errors, and each data element is considered valid. Part II contains records for the current reporting period that contain errors that have not been previously corrected. Part III will be produced only if there are correction or deletion records that cannot be applied to the local database due to erroneous data. In part III, an asterisk (*) indicates erroneous data. When erroneous data is indicated, the work center supervisor should verify the MAF copy 1 daily audit report to ensure that data that is contained on production work center MAFs has been correctly processed by the DSF. Monthly Production Report (MDR-2) The MDR-2, shown in figure 5-2, lists all maintenance actions in work center sequence, which includes technical directive compliance and data that has been entered in the (H-Z) Failed/Required Material blocks of the MAF. The MDR-2 also provides the work center supervisor with statistical data that pertains to the work center, for example, man-hours that were expended in repair of a subsystem. 5-3 Job Control Number (JCN) Consolidation Report (MDR-3) The MDR-3 (fig. 5-3) is a consolidated list of all maintenance and technical directive compliance actions that were submitted during the month by the parent organization and the supporting activity. This report is prepared from data on all MAFs except those with transaction codes 00, 02, and 03 (inventory gain, change in material condition reporting status, and inventory loss). The MDR-3 gives the maintenance officer (MO) a record of maintenance on the equipment for which he or she is responsible. of coded elements that the DSF summarizes into daily and monthly reports. For a detailed description and examples of MDS reports, refer to the Naval Avia- tion Maintenance Program (NAMP), OPNAV- INST 4790.2. Some of the DSF-generated MDS that we will discuss are available in both organizational- and intermediate-level maintenance activities. MAF Copy 1 Daily Audit Report (DAR)
