INSTALLED EXPLOSIVE SAFETY DEVICES (OPNAV 4790/26A)

This form (fig. 1-1) is used in the logbook and the Aeronautical Equipment Service Record (AESR). This section of the logbook/AESR contains a record of all explosive safety devices (for example, initiators and canopy releases) installed in the aircraft/major assemblies. Explosive devices installed in major assemblies/ equipment (for example, ejection seats and inflight refueling stores) must be recorded in the Installed Explosive Safety Devices page of the appropriate AESR. Explosive devices installed in personnel parachutes are recorded on the Parachute Configuration Inspection and History Record, and when installed in other safety and _{survival equipment,} on the History Card -Aviation Crew System. All other explosive safety devices must be recorded on the Installed Explosive Safety Devices Form of the logbook/AESR. This form is not required when the recording of escape system explosive components in F-14A aircraft is done in accordance with NAVAIR 11-100-1.1 (NOTAL).

Certain equipment is transferred from one aircraft to another during SDLM and replaced during periods of scheduled maintenance. This emphasizes the need to carefully and periodically check this record regarding the status of the explosive devices currently installed in the aircraft/equipment. This record is maintained in a current status by all activities having custody of performing rework on the aircraft/equipment in which explosive safety devices are installed.

Documentation requirements is a must. A single line entry is required for each installed explosive safety device. All data columns must be complete.

The following information explains what to report in each block.

Block 1-Aircraft Equipment/Model No. Enter the aircraft or equipment T/M/S.

Block 2-BUNO/Serial No. Enter the aircraft BUNO or equipment serial number.

Block 3-DODIC. Enter the Department of Defense Identification Code (DODIC) or the

Figure 1-1.-Installed Explosive Safety Devices (OPNAV 4790/26A) (Logbook) (AESR). 1-12

Navy Ammunition Logistic Code listed in the Navy Ammunition Stock Microfiche, TWO10-AA-ORD-010/NA 11-1-116A (NOTAL). DODICs are also specified in the four technical manuals mentioned in the details for block 11.

Block 4-Nomenclature or Type of Device. Enter the name/type device.

Block 5-Lot No. Enter the lot number of the device.

Block 6-Serial No. Enter the serial number of the device. For devices not serialized, enter"NA."

Block 7-Purpose or Location. Enter the purpose or the location of the device.

Block 8-Installing Activity/Date. Enter the short title of the activity and the month and year that the device was installed; for example, VA34/JUL90.

Block 9-Container Open Date. Enter the month and year the container was opened; for example, JUL 90. When the container open date is not required for AEPS devices, "NA" will be entered.

Block 10-Date of Manufacture. Enter the date, month, and year of manufacture; for example, JUL 90. For CADS enter manufacture date, and for AEPS enter propellant manufacture date.

Block 11-Expiration Date. Enter the computed month and year; for example, JUL 90. Installed service-life expiration dates for explosive devices are computed from the date of manufacture, the date the hermetically sealed container is opened, and the date the device is installed. The method used in computing the expiration date of explosive devices and the number of months/years a specific device may remain in service is contained in NA 1185-1-1.2(NOTAL), NA 11-100-1.1(NOTAL), NA 11-100-1.2(NOTAL), and NA 11-100-1.3(NOTAL). When installed explosive safety devices have extensions granted, the expiration date will be updated by drawing a line through the old expiration date and placing the new expiration date above it. The authority granting the extension, for example, message originator and date time group (DTG or IRAC number and manual), will be logged in the Remarks Column (block 12).

Block 12-Remarks. Make applicable remarks. This block is limited in size; use the Miscellaneous/History page if additional space is required.

Block 13-Removal Date. Enter the month and year the device was removed; for example, JUL 90.
