the interim rapid action change [IRAC] number and manual affected) should be logged in the Remarks or Local Use column. A single-line entry is required for each installed explosive device. All data columns must be completed. For nonserialized devices and devices that do not require a container open date, you should enter NA in the appropriate columns. When explosive devices are installed in major assemblies or equipment (such as ejection seats and in-flight refueling stores), entries are made in the Installed Explosive Device Record of the appropriate AESR. When explosive devices are installed in personnel parachutes, entries are made on the Parachute Record. Explosive devices installed in other safety and survival equipment are recorded on the Seat Survival Kit (SSK) Record or Aircrew Systems Record. The installation of all other explosive devices is recorded on the Installed Explosive Devices Record of the aircraft logbook. The possibility of transferring certain equipments from one aircraft to another during inspections, rework, periods of periodic maintenance, etc., emphasizes the need for careful and periodic checking of the Installed Explosive Device Record regarding the status of the explosive devices currently installed in the aircraft. The Installed Explosive Device Record is maintained in a current status by all activities that have custody of and perform rework on aircraft in which explosive devices are installed. During SDLM, the rework activity transcribes all current information to a new form and discards the old form. Q21. When the Installed Explosive Device Record is documented, what specific entry should be entered in the Serial Number block for nonserialized devices? INVENTORY RECORD (OPNAV 4790/27A) The Inventory Record form, shown in figure 6-12, is used to maintain a current inventory of all components or assemblies that require ASRs, EHR cards, SRC cards, and MSRs. Mission configuration items, such as bomb racks or searchlights, are not required to be entered on this record. It is impractical to include a specific list of such components since requirements vary according to the aircraft model. However, all airframe components/ assemblies that require an ASR, an EHR, an SRC card, or items that require an MSR should be recorded on this record. Sound maintenance practices and flight safety considerations dictate the items, other than mandatory, that should be recorded on this form. Aircraft engines, propellers, auxiliary power units, ejection seats, and other major assemblies that require an AESR are NOT listed on this or any other form in the aircraft logbook. Remember, components, assemblies, or modules associated with equipment that require an AESR are to be recorded in the applicable section of AESRs and not with airframe components in the aircraft logbook. NOTE: AESR, SRC card, EHR, ASR, MSR, Parachute Record, Seat Survival Kit Record, Aircrew Systems Records, and Aircrew Personal Equipment Record items are inventoried during each phase inspection for the applicable equipment that is being inspected. A locally prepared form that lists items that require an ASR, MSR, EHR card, or SRC card should be used. This form should consist of a preprinted item list with a column to record item serial numbers. The items in the list should match the record of installed items in the aircraft. ASSEMBLY SERVICE RECORD (ASR) (OPNAV 4790/106A) The Assembly Service Record (ASR) (figs. 6-13 and 6-14) provides data tracking on assemblies and subassemblies that have rework or overhaul life limits and are designated to be removed at organizational-, intermediate-, or depot-level maintenance activities and discarded. The loss of an ASR can cause the loss of the assembly to the supply system; therefore, you must be able to reconstruct the assembly’s history to determine a course of action if the ASR is not available. The Aeronautical Time Cycle Management Control Repository at COMNAVAIRSYSCOM determines what action is needed if an ASR is lost. To enable the repository to accomplish this task, the repository must receive misplaced and canceled ASRs, copies of all updated records after rework, and copies of all new ASRs generated for new ASR items. A description of the ASR follows. The top section of the ASR is used to identify the assembly by nomenclature and to record the assembly’s replacement due, replacement interval, and time remaining information. Replacement due indicates the number of hours or counts on the equipment or aircraft at which time the 6-20
