Where the ATA 32 records repeat and connect.
This map groups published records by IPC figure. It is a catalog relationship map, not a hydraulic schematic or system-operation diagram.

AC61518, AC67732, and AC69784 appear in both the valve-and-mounting figure and the wheel-brake piping figure. Repeated placement gives catalog context. It does not establish flow direction, internal function, or interchangeability.
Valve records by figure and item
| Part number | IPC name used for this site | Figure and item | Printed configuration note | Quantity |
|---|---|---|---|---|
| AC61518 | Brake reducing valve | 32-40-10-10 item 165; 32-40-20-10 item 10 | Unit exchange item | 1 |
| AC67732 | Brake control valve assembly | 32-40-10-10 item 65; 32-40-20-10 item 15 | MOD state 4; unit exchange item | 1 |
| AC69784 | Emergency reducing valve assembly | 32-40-10-10 item 170; 32-40-20-10 item 20 | MOD 253522A | 1 |
| AH081963 | Outer shuttle valve assembly | 32-40-30-10 item 355 | Unit exchange item | 1 |
| AH081964 | Inner shuttle valve assembly | 32-40-30-10 item 405 | Unit exchange item | 1 |
Every row in this comparison prints effectivity 8266-8999. The technical source supports the printed identities and catalog locations.
Why three valves appear twice
AC61518, AC67732, and AC69784 each appear in Figure 32-40-10-10 and Figure 32-40-20-10. The first is the valve-and-mounting breakdown. The second is the wheel-brake piping breakdown. Repeated catalog placement helps confirm the same part identity in two assemblies.
It does not establish pressure direction, hydraulic sequence, port function, or internal operation. Those subjects require the applicable system schematic and maintenance data.
Configuration notes that need to stay on the request
AC67732 is printed as MOD state 4. AC69784 is printed with MOD 253522A. Those are not side notes to drop from a quote request. The offered unit’s identification and release documents should show the configuration required for the aircraft.
AC61518 and AC67732 are identified as unit exchange items in the reviewed rows. Exchange status does not establish the condition or modification state of a particular unit. Confirm the core, offered condition, release paperwork, and repair-source capability separately.
The AC69784 CMM conflict
The two AC69784 rows agree on the part number, name, quantity, effectivity, and MOD 253522A. They do not agree on the maintenance reference:
- Figure 32-40-10-10 prints CMM 32-44-32
- Figure 32-40-20-10 prints vendor CMM 29-09-08
This guide does not choose one reference. The discrepancy is carried forward as an unresolved source conflict. Check the current IPC and applicable approved technical data before using either CMM reference for maintenance.
Inner and outer shuttle valves
AH081963 is the outer shuttle valve at item 355. AH081964 is the inner shuttle valve at item 405. Both rows reference CMM 29-09-10 and identify the unit as an exchange item.
Inner and outer are separate catalog positions with separate numbers. The reviewed IPC does not state that one can replace the other. Keep the exact position and removed-unit identity on the request.
What this map can support
Use this page to locate the correct part record, preserve the figure and item, compare repeated catalog placements, and spot the modification or source note that needs follow-up. Do not use it as a troubleshooting chart, plumbing diagram, or installation instruction.
Direct lookup answers
Common questions.
Which Hawker brake-control valve is identified as MOD state 4?
AC67732 is identified as the brake control valve assembly at MOD state 4 in both reviewed ATA 32 rows. Both rows print effectivity 8266-8999.
Why does AC69784 show two different CMM references?
The supplied export is inconsistent. Figure 32-40-10-10 prints CMM 32-44-32, while Figure 32-40-20-10 prints vendor CMM 29-09-08. Current technical data must resolve the reference.
Are AH081963 and AH081964 interchangeable shuttle valves?
The reviewed IPC does not say that. It assigns AH081963 to the outer position and AH081964 to the inner position as separate part numbers.
