Approved sources

Every maker's reference the catalogue files against this item of supply — the parts someone holding this number can use. The design-control reference is the one that controls the item; a secondary reference is a real codified fact and a weaker one.

Historical & informational references

Numbers the catalogue records against this item but marks as not for procurement — withdrawn entries, information-only listings, drawings, and references that need more than the number to identify the item. If you arrived holding one of these, this is the item it points to; the sources above are what can actually be used.

no longer valid — this reference was withdrawn from the catalogue record (RNVC 9) — the history trail: hold it, do not buy to it

Substitutes — other stock numbers

Codified interchangeability across stock numbers (FLIS I&S), with the catalogue's order of use where it states one.

Export paused

The monthly allowance for this address is used — the pattern reads as catalogue work, not a line to settle.

Whole-catalogue work is what Stage 1(a) is for: every line human-checked against the cited evidence, discrepancies annotated, back inside 24 hours. Free searching stays free — this gate only catches bulk pulls.

Staying inside the regulation — routes from candidate to approved

Codification and qualification say who vouches for a part — they are not installation eligibility. Under EASA Part-21, eligibility flows from the approved design (type design / IPC) or an approved change; under Part-145, acceptance needs an EASA Form 1 or, for genuine standard parts, conformity traceable to the officially recognised standard (145.A.42).

  1. Classify the part. Is it a GENUINE standard part? If the IPC/CMM references only a public specification (AN/MS/NAS/SAE-AS/ISO/EN) with no OEM source-control drawing, buy at source with conformity traceable to that standard.
  2. Check for an approved alternate. The IPC/CMM/vendor list may already carry an alternate part number or vendor code — an already-approved alternate needs no new approval.
  3. Ask the design approval holder. Request the source-control data, written equivalence, or addition of the alternative source to the approved data. Document a refusal.
  4. Raise a design change. Via a Part-21J DOA (or EASA/ADOA): a 21.A.95 minor change adding the alternate to the approved data, backed by an identicality/equivalence file — dimensions, material, class, load rating, lubricant/seal, corrosion protection, acceptance criteria. Critical applications escalate to major change/STC.
  5. FAA-PMA / BASA path. Where the product is also FAA-certificated: PMA parts reach EASA aircraft under the BASA/TIP (non-critical directly; critical via EASA-validated STC).
  6. Production, release, traceability. Approved parts are produced under a POA, released on an EASA Form 1 (marked EPA where applicable), with EN/AS 9120-grade traceability into Part-145/CAMO acceptance.

Stage 1(a): we assemble the equivalence/identicality starter file — the cited evidence this graph holds, shaped for your DOA or compliance department to take forward. See pricing.

Regulatory explainer, not legal advice: paragraph numbers, derogations and the BASA/TIP revision change — verify against the current consolidated Regulation (EU) 748/2012, the EASA Easy Access Rules and the current TIP, and engage your DOA and competent authority early.
