Stock number · one item of supply — the parts codified against it, and the stock numbers it substitutes for
← Search another part, spec or stock number
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.
NONMETALLIC CHANNEL
design-control reference — the reference that controls this item of supply (RNCC 3 · RNVC 2)
Also filed by the same company as 287-1009PT1 (49956) — one product, several catalogue rows.

NONMETALLIC CHANNEL
codified reference — recorded against this stock number; the catalogue grade is not held
Numbers the catalogue records against this item but marks as not for procurement — withdrawn entries, information-only listings, drawings, and references that need more than the number to identify the item.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.
NONMETALLIC CHANNEL
no longer valid — this reference was withdrawn from the catalogue record (RNVC 9) — the history trail: hold it, do not buy to it

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