Hawker 800XP AIR45396 Steering-Jack Replacement Chain

The two IPC figures answer different catalog questions

The AIR45396 family appears in two ATA 32 locations:

IPC location	What is printed there	Numbers involved
Figure 32-20-00-30 item 185	Nose-gear installation, alternate-spare language, and used-on parent assemblies	AIR45396, AIR45396-6, AIR45396-7
Figure 32-50-00-15 item 10	Nose-wheel steering breakdown and forward spares directions	AIR45396, AIR45396-5, AIR45396-7

Both locations print quantity 1, effectivity 8266-8999, and CMM 32-50-1103. Those matching fields help establish that the rows belong to the same steering-jack family. They do not remove the differences in the relationship language.

The forward spares directions

The steering breakdown gives two direct instructions:

• AIR45396 says to order AIR45396-7 for spares
• AIR45396-5 says to order AIR45396-7 for spares

Read those arrows in the printed direction. The export does not say that an AIR45396 or AIR45396-5 can be supplied in place of an AIR45396-7 request.

AIR45396-5 is also marked as a unit exchange item. That note affects the expected commercial transaction, such as core eligibility and return terms. It does not create interchangeability by itself.

The alternate-spare group and parent assemblies

The nose-gear installation figure groups AIR45396, AIR45396-6, and AIR45396-7 as alternate spares. The same row set prints used-on parent assemblies:

Steering-jack number	Used-on parent assemblies printed in the export
AIR45396	25-8UN1-363A; 25-9UN1-83A
AIR45396-6	25-9UN1-353A; -355A; -363A; -375A; -383A
AIR45396-7	25-9UN1-389A; -395A; -401A; -407A

The shortened suffixes in the table retain the 25-9UN1 prefix from the first number in each row. Use the full number from the source or aircraft record on a quote request.

These parent-assembly notes are the reason a useful lookup cannot stop at “AIR45396 alternate.” The exact removed number and next higher assembly need to stay together.

What to put on the quote request

Start with the removed-unit data plate and the aircraft record. Include:

1. The complete AIR45396 family part number, including the dash number.
2. The steering-jack serial number when available.
3. Aircraft model and full aircraft serial number.
4. The 25-8UN1 or 25-9UN1 parent-assembly number.
5. Required condition, release paperwork, and traceability.
6. Exchange-core part number, serial number, and return requirements.

If the offered unit uses another family number, ask the source to identify the current approved data supporting that configuration.

What this chain does not establish

This catalog comparison does not provide steering rigging, hydraulic servicing, leakage limits, actuator travel, overhaul criteria, or return-to-service instructions. The CMM reference points the technician toward maintenance data, but the CMM itself is not part of the supplied source set.

Use this guide to keep catalog identities and cross-reference language straight. Use the applicable approved manuals and aircraft records for maintenance and installation decisions.
