Cross-reference check

Relationships and limits.

  • The reviewed row references CMM 29-10-3 and gives no printed supersession.
  • 2125H4 is separate from 25HC31A and AIR87366-0, which occupy different filter positions in the same ATA chapter.
Important limit

Do not select an internal filter element from the assembly number alone. Element identity, bypass condition, servicing, and maintenance limits require the applicable component and aircraft data.
