Installed Explosive Safety Devices (OPNAV 4790/26A)

The Installed Explosive Safety Devices form, shown in figure 6-9, contains a record of all the explosive safety devices currently installed in the aircraft. These include, but are not limited to, lap belt cartridges, initiators, canopy release and seat ejection cartridges, or devices.

When explosive devices are installed in major assemblies or equipment (such as ejection seats and in-flight refueling stores), an entry or entries is/are made in the Installed Explosive Safety Devices form of the appropriate AESR. When explosive devices are installed in personnel parachutes, an entry is made on the parachute record. Explosive devices installed in other safety and survival equipment are made on the history card-aircrew systems record. The installation of all other explosive safety devices is recorded on the Installed Explosive Safety Devices form 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 necessity for careful and periodic checking of this record regarding the status of the explosive devices currently installed in the aircraft.

Expendable ammunition and stores and the associated igniters and fuses are not intended for inclusion in this record. However, information concerning certain cartridges or devices used to expel stores may be entered in this section if specifically directed for a particular application.

A single-line entry is required for each installed explosive safety device, and you must complete all data columns. For nonserialized devices and devices that do not require a container open date, you should enter NA in the appropriate columns. For the Department of Defense Identification Codes (DODICs), you should refer to Navy Ammunition Stock Microfiche, TW010-AA- ORD-010/NA 11-1-116A.
