Buying aircraft hardware without documentation is a common shortcut with serious consequences. The FAA Form 8130-3 Authorized Release Certificate is the document that makes surplus aircraft hardware legally distinguishable from uncertified parts. If you've seen "ships with 8130-3" on hardware listings and weren't entirely sure what that means — this guide explains every aspect of the form, who issues it, and what protection it actually provides.
What the 8130-3 Is
FAA Form 8130-3 is the Authorized Release Certificate / Airworthiness Approval Tag. It has two distinct uses depending on context: it certifies that a new part conforms to the approved design data and is in condition for safe operation, or it certifies that a used part has been returned to airworthy condition by an approved maintenance entity.
The primary purpose of the 8130-3 is traceability — it creates a documented chain from the manufacturer (or approving entity) to the installer. That chain is what makes the hardware legally distinguishable from an unapproved or counterfeit part. Without 8130-3 documentation on surplus hardware, you have no way to verify the part's origin, material, or production history beyond the physical item itself.
The form is governed by FAA Order 8130.21 and accepted by EASA under bilateral agreement (though EASA uses Form 1 as their equivalent). For international shipments, the 8130-3 is recognized as the U.S. release document.
Who Can Issue an 8130-3
Not everyone can sign an 8130-3. The issuer must hold specific FAA authorization, and the issuer's credentials should always be verified as part of hardware acceptance.
- Production Approval Holders (PAH): Manufacturers holding a Production Certificate (PC), Parts Manufacturer Approval (PMA), or Technical Standard Order (TSO) Authorization. This is the most common source for new hardware — the original manufacturer issues the 8130-3 as part of production.
- Designated Manufacturing Inspection Representatives (DMIR): FAA-delegated individuals authorized to approve parts on behalf of PAH manufacturers.
- FAA Aviation Safety Inspectors (ASI): FAA employees directly authorized to issue 8130-3 forms for new production and return-to-service approvals.
- FAA-Certificated Repair Stations (Part 145 CRS): Can issue 8130-3 for used parts returned to service within their approved ratings.
- Air Carriers (Part 121/135): Can issue 8130-3 for parts within their maintenance program scope.
The issuer name and authorization number appear in Block 13c of the form. Always verify this block when accepting hardware from a new supplier.
How to Read the Form — Block by Block
The 8130-3 has 20 numbered blocks. For new AN/MS surplus hardware, the critical blocks are:
| Block | Field Name | What to Check |
|---|---|---|
| Block 1 | Approving Authority / Country | Should read "FAA / United States" for domestic new hardware |
| Block 7 | Description | Part description — verify matches what you ordered |
| Block 8 | Part Number | Exact part number — check against your order. AN4-7A not the same as AN4-7. |
| Block 9 | Eligibility | Aircraft type or "All" for general AN/MS hardware |
| Block 10 | Quantity | Must match quantity shipped to you |
| Block 11 | Serial/Batch Number | Lot number for traceability back to manufacturing batch |
| Block 12 | Status / Work | For new surplus: reads "NEW". For overhauled parts: reads "OVERHAUL". |
| Block 13a | Certifies conformance | Checkbox for "new" conformance — must be checked for new hardware |
| Block 13b | Certifies airworthiness | Checkbox for return-to-service — checked for used/repaired parts |
| Block 13c | Authorized Signature | Name, certificate number, date — the issuer's legal authorization |
| Block 14a | Certifying Statement | Regulatory basis for the certification — PAH will cite their production approval |
| Block 19 | Remarks | Any limitations, exceptions, or conditions. For clean new hardware this should be empty or contain only storage/handling notes. |
For new AN/MS hardware from a PAH: Block 12 reads "NEW", Block 13a is checked, Block 13b is unchecked, and Block 19 should be empty or unremarkable. If Block 19 contains language like "not eligible for installation on type-certificated aircraft" or any airworthiness limitation, that changes the regulatory basis for installation.
What "New Surplus With 8130-3" Means
The phrase appears constantly in hardware listings. It means the part was manufactured under a production approval, passed inspection at the production facility, was issued an 8130-3 at the time of manufacture, and was never installed on an aircraft.
New surplus typically originates from contract cancellations, program overstock, manufacturer inventory rationalization, and government surplus. The hardware was made, documented, and stored — it just didn't go through normal distribution channels. This distinction matters:
- New surplus with 8130-3: Full documentation from original PAH. Same hardware as new production, different distribution path. Eligible for installation on certificated aircraft under the same conditions as any new part. This is what we sell.
- New surplus without 8130-3: May be legitimate surplus hardware, but provenance cannot be verified. No legal basis for installation on type-certificated aircraft without additional investigation. Not appropriate for primary structural use.
- Used / pulled hardware: Removed from a previous installation. Requires return-to-service approval (Block 13b on 8130-3, issued by Part 145 CRS) to be reinstalled on certificated aircraft. Condition is variable. We do not sell used pulled hardware for structural AN/MS fasteners.
For EAB builders and MRO shops doing certificated work, the 8130-3 on new surplus hardware is the document that puts it in the same legal category as hardware purchased new from a distributor.
What the 8130-3 Does NOT Do
The form is powerful documentation, but it has clear limits that the mechanic and builder must understand:
- Does not authorize installation by itself. The 8130-3 certifies the part's conformance and condition. The maintenance record entry, logbook signoff, or repair station documentation authorizes the actual installation. The 8130-3 is attached to that record, not a standalone authorization.
- Does not certify remaining service life for life-limited parts. For time-limited parts, the applicable overhaul manual or airworthiness limitation governs remaining life — the 8130-3 doesn't address this.
- Does not replace engineering judgment. Correct part number, correct spec, correct application — the 8130-3 doesn't verify you're using the right part for the job. That's the installer's responsibility.
- One 8130-3 cannot cover multiple serialized parts. Each serialized part requires individual documentation. For non-serialized parts like AN bolts, lot coverage is acceptable — verify that Block 10 (quantity) matches what you received.
The 8130-3 and Experimental Aircraft
Under FAR Part 21.191, experimental amateur-built aircraft are exempt from the type certification requirements that mandate approved-parts installation. Strictly speaking, the 8130-3 is not legally required to install AN/MS hardware on an experimental aircraft.
However, there are strong practical reasons for EAB builders to use documented hardware anyway:
- Traceability at condition inspection: DAR inspectors and EAA technical counselors are increasingly asking for parts documentation. Having 8130-3s in the aircraft records simplifies the inspection process.
- Resale value: An experimental aircraft with documented hardware sells for more and sells faster. Buyers — especially buyers who fly a lot — care about what's in the airframe.
- The hardware is the same either way: You're not paying a premium for the 8130-3 on new surplus — you're paying for surplus pricing on hardware that already has full documentation. There's no cost reason to skip the documentation.
AeroSpaceSpecBolt includes 8130-3 on all hardware regardless of whether the buyer is building experimental or performing certificated maintenance. The documentation costs nothing extra when it already exists — and it's the kind of thing you don't think about until you need it.
