Mechanic's lookup notes

Common questions about AIR45408.

What part number replaces AIR45408 for spares?

Both reviewed catalog placements tell the reader to order AIR45408-0 for AIR45408 spares. Confirm the offered unit and aircraft configuration against current approved data.

Why does AIR45408 appear in ATA 29 and ATA 32?

The same steering-valve identity is carried in a hydraulic-system figure and the nose-wheel steering breakdown. Repeated placement supplies catalog context, not a flow schematic.

Which CMM is referenced for AIR45408?

The IPC references CMM 32-50-1108 in both rows. The CMM was not supplied here, so this page does not state maintenance or test procedures.
