IPC record
Identity and application.
The reviewed catalog row establishes the part identity and its location in the combined Hawker IPC. It does not establish the condition of a particular unit or approve that unit for installation.

Cross-reference check
Relationships and limits.
- Both IPC rows print quantity 2 for the ZM and ZN battery positions.
- The two catalog figures carry different serial-effectivity lists, so both placements remain visible.
- Concorde lists STC ST00415LA as the Hawker 800 and 800XP path for replacing 23491 or 23491-3 with two RG-390E batteries.
The IPC placement and the manufacturer STC eligibility are separate evidence. Installation of RG-390E in place of a nickel-cadmium battery requires the applicable approved STC data and configuration work, not just a matching directory record.
Mechanic's lookup notes
Common questions about RG-390E.
Is RG-390E listed for the Hawker 800XP?
Yes. It appears in the reviewed IPC and in Concorde manufacturer eligibility material for Hawker 800 and 800XP aircraft.
Can RG-390E replace 23491-3?
Concorde identifies that replacement under STC ST00415LA using two RG-390E batteries. The approved STC instructions and aircraft records control the installation.
Why are the RG-390E effectivity blocks different?
The rows come from two different ATA 24 figures. The part record preserves both printed lists rather than forcing them into one simplified serial range.
