Aircraft-part documents: CoC, FAA 8130-3 and EASA Form 1
Understand common aircraft-parts documents, match identity and condition to the quotation, and clarify acceptance requirements before ordering.
Ask about this requirementThe quick answer
Ask which documents will accompany the exact item before approving a quotation. A supplier or manufacturer CoC, FAA Form 8130-3 and EASA Form 1 serve different purposes; their presence is not automatically interchangeable. Match the document to the P/N, serial or batch, quantity, condition and issuing organisation. The applicable acceptance and installation requirements depend on the aircraft, jurisdiction and transaction and must be confirmed by the responsible organisation.

State the required evidence before price comparison
Include required release documents, traceability and material or test certificates in the enquiry. If the requirement is uncertain, ask your maintenance or receiving organisation to define it. Quotes for the same P/N may cover different condition, documentation, warranty or exchange terms. Compare the complete scope, not only the unit price. The word “certified” on its own does not identify the certificate, issuer or covered item.
Check identity, remarks and scope together
Read the document as a whole. Check P/N, description, S/N or batch where applicable, quantity, date, stated condition or work and remarks. A release for a different serial number, an attachment missing from the reference, or a discrepancy between the label and document needs clarification before acceptance. Keep the delivered record and its supporting documents together with the purchase reference.
Separate release status from installation eligibility
FAA and EASA explain that their release forms do not, by themselves, approve installation on a particular aircraft, engine or propeller. The responsible receiver or installer must establish eligibility using the applicable technical and regulatory basis. This guide explains purchasing questions; it does not decide whether one release is acceptable in a particular Israeli or cross-border maintenance situation.
What to compare
| Document | Purchasing question | Important distinction |
|---|---|---|
| CoC | Who issued it, and what requirement/item does it cover? | Scope depends on the actual statement and issuer |
| FAA Form 8130-3 | What item, status and remarks are recorded? | Not an aircraft-specific installation approval |
| EASA Form 1 | Does its release scope meet the receiving requirement? | Acceptance and installation eligibility still need review |

Common questions
Should every enquiry request the same certificate?
No. Define the document requirement for the item, its condition, receiving organisation and applicable rules before ordering.
What if a serial number does not match?
Keep the item and records identified and ask the supplier and responsible receiving organisation to resolve the discrepancy before acceptance or use.
