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.

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).
- 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.
- 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.
- 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.
- 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.
- 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).
- 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.
