Cross-reference check

Relationships and limits.

  • The hydraulic row calls for quantity 2 and references CMM PAO396.
  • Because HTE4350 is also cataloged in ATA 28 positions, system context is required to avoid a false match.
Important limit

HTE4350 also appears in Hawker fuel-system records. A part-number-only search can mix systems, so the hydraulic figure, item, and requested function must stay with the quote.
