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 in-
flight 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 log-
book/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.
