Scheduled Removal Component (SRC) Card (OPNAV 4790/28A)

Figure 7-16.—Module Service Record (OPNAV 4790/135). Once the module is installed in a particular propulsion system, this record is maintained concurrently with, and becomes part of, the propulsion system AESR. Assembly Service Record (ASR) (OPNAV 4790/106A) The ASR (fig. 7-17) is a two page form that provides data tracking on assemblies. Items that require an ASR are items with rework or overhaul life limits and subassemblies designated to be removed by any organization and discarded. Equipment History Record (EHR) Card (OPNAV 4790/113) The EHR card (fig. 7-18) is a two page form used to record maintenance, inspections, TD compliance, and usage data on maintenance engineering cognizant field activity (MECFA) designated components, quick engine change kits (QECKs), and armament equipment. An individual card for each EHR component is maintained as part of the aircraft logbook, AESR, or MSR while the component is installed in or on the aircraft. When the component is removed, the EHR accompanies the component. Scheduled Removal Component (SRC) Card (OPNAV 4790/28A) The SRC card (fig. 7-19) is used to record maintenance history data of aeronautical components that are (through engineering analysis) determined to be life limited. The SRC card is used to record maintenance history, installation, and usage data on designated SRCs. An individual card for each SRC item is maintained as part of the logbook, AESR, MSR, or equipment as long as that item is installed. When the item/component is removed from the aircraft, the SRC card accompanies the component. 7-17
