Approved suppliers (ASL)

The Approved suppliers screen holds the ASL (Approved Supplier List): the sources whose fitness the organisation has validated. This is a Part-145 requirement — a maintenance organisation must control its sources.

Catalog ≠ approval

Two distinct things, not to be confused:

  • A supplier may sell an item (catalog) without you being allowed to buy it from them.
  • An order (a later phase) is only possible from an approved source valid on the date — unless a traced derogation (AOG, sole source), which will come later.

What an approval holds

  • The supplier and its approval reference.
  • Evidence (certificate, supplier audit) — an optional document.
  • A validity (from / to).
  • A status: Approved, Suspended (temporary, reversible) or Revoked. Suspended blocks like revoked; the distinction is informative.
  • One or more scopes: an approval rarely covers a single item, rather a category or an ATA chapter. Each scope targets exactly one item or category or ATA chapter.

Expiries first

Approvals expiring within 90 days rise to the top, with a badge. An approval that expires unnoticed blocks purchasing overnight — the risk this screen makes visible.
