The blank looks simple. The track you are on is not. EASA Form 1 is an Authorised Release Certificate (FAQ 19466). It declares airworthiness of a product, part or appliance. It is not a delivery note, not a release of an aircraft, and not by itself authority to install on a particular aircraft, engine or propeller. The form says that last point in the user/installer block.
Who may complete it depends on production vs maintenance. Same form family. Different sides, different Block 11 words.
Key takeaways
- Production (POA / Part-21) signs blocks 13a–13e. Maintenance (Part-145 / CAO / Part-M) signs 14a–14e. Never both.
- After maintenance, Block 11 is only Overhauled, Repaired, Inspected/Tested, or Modified (FAQ 19044).
- Block 12 must detail the Block 11 work. “In accordance with the CMM” is not acceptable in the QCM restatement of the appendix.
- Do not mix production-released and maintenance-released items on one certificate. Do not mix approved-data and non-approved-data items on one certificate.
- A correction needs a new tracking number. Keep both certificates.
- Matching Blocks 7/8/10 to invoice and AWB is packet correlation if the article is moving. It is not a filling rule.
- Doana can extract the blocks from a PDF. It cannot sign, correct, or file the form.
Which track are you on, production or maintenance?
Production (POA holder): Form 1-21, Regulation (EU) No 748/2012 Appendix I to Annex I (Part-21) (legislation.gov.uk Appendix I). Maintenance (Part-145 / CAO / Part-M): Form 1-MF/CAO/145, Appendix II to Annex I (Part-M) of Regulation (EU) No 1321/2014.
Do not mix production-released and maintenance-released items on one certificate. Do not mix approved-data and non-approved-data items on one certificate. Correlation must exist between the certificate and the item.
QCM REV05 restates those appendices (QCM, vendor). Use it as a map; the legal text is the appendix.
| Track | Block 11 | Certification blocks | Other side |
|---|---|---|---|
| Production (Part-21) | PROTOTYPE or NEW | 13a–13e (approved vs non-approved design data, signature, approval number, name, date dd mmm yyyy) | 14 shaded |
| Maintenance (Part-145 / M / CAO) | Overhauled, Repaired, Inspected/Tested, or Modified | 14a–14e | 13 shaded |
FAQ 19044 (28 Jan 2021): after maintenance, those four Block 11 entries are the permissible set. “Inspected/Tested” means inspected and/or tested as in Part-M/Part-145. Block 12 should contain the detailed information on the status/work in Block 11.
Do not copy FAA Part 21 terms (NEW / PROTOTYPE / USED) onto Form 1. That split lives on 8130-3 Block 11.
What goes in each block?
Fourteen blocks, one track. Blocks 1–12 identify the organisation and the item. Blocks 13 and 14 are the certification sides. You complete one side. The other is shaded. Prefer ICA / CMM / IPC terms in Block 7. Put the part number as on the item in Block 8.
| Block | Content |
|---|---|
| 1 | Competent authority and country, or “EASA” when the Agency is the authority |
| 2 | AUTHORISED RELEASE CERTIFICATE EASA FORM 1 |
| 3 | Unique tracking number |
| 4 | Organisation name and address |
| 5 | Work order, contract or invoice |
| 6 | Item numbers |
| 7 | Description (prefer ICA / CMM / IPC terms) |
| 8 | Part number as on the item |
| 9 | Quantity |
| 10 | Serial number or N/A |
| 11 | See table above |
| 12 | Work detail / supporting data (see remarks) |
| 13 / 14 | Production or maintenance certification, not both |
What belongs in Block 12 remarks?
FAQ 19044: Block 12 details the Block 11 work. QCM’s restatement of the appendix: “In accordance with the CMM” is not acceptable. Examples it lists (vendor restatement, not a substitute for GM): AD/SB compliance, repairs, modifications, replacement parts, LLP status, shelf life, NDT methods, deviations, foreign CAA statements, batch numbers. EASA GM 145.A.50(d) is the continuing-airworthiness home for release-to-service remark practice (Easy Access Rules).
Illustrative pair (not a real certificate):
| Weak Block 12 | Better Block 12 (illustrative) |
|---|---|
| In accordance with the CMM | Inspected/tested per CMM 32-41-13 Rev 12, task 05-20-00; no defects found; NDT not required |
MAG dual-release remarks for a used US 8130-3 live on that FAA tag (Block 12 + 14a), not as a second Form 1 (BASA FAQ; FAQ 43770). Dual-release page: Dual release on FAA 8130-3.
What does a filled maintenance line look like?
A filled line is Blocks 7–12 plus the maintenance certification in 14, with 13 shaded. The values below are invented for teaching. They are not a real release. Do not photocopy them into service.
| Block | Illustrative value |
|---|---|
| 7 | BRAKE ASSEMBLY, MAIN WHEEL |
| 8 | 2-1585-3 |
| 9 | 1 |
| 10 | SN 4412 |
| 11 | Repaired |
| 12 | Repaired per CMM 32-41-13 Rev 12, SB 32-114 embodied; LLP cycles remaining recorded on attached card |
| 14 | Part-145 certification (13 shaded) |
How do you correct a Form 1, including an electronic one?
Identify errors in writing to the originator. A correction needs a new tracking number, signature and date. Block 12 on the correction states which blocks of the original it corrects and that it does not cover conformity/condition/release to service. Keep both certificates.
Electronic Form 1: do not allow signing a blank form; preserve integrity after signature. QCM restates printed copies watermarked “PRINTED FROM ELECTRONIC FILE.” Data exchange may use ATA Spec 2000 Chapter 16.
FAQ 66700 is which foreign ARCs a Part-145 organisation may accept, not how to fill Form 1. Equivalents: “Form 1 or equivalent”.
Matching Blocks 7/8/10 to invoice and AWB is packet correlation if the article is moving. It is not a filling rule and not a customs valuation method.
Next
Pick the track first. Then fill Block 11 from that track’s list, and make Block 12 detail that work. Matching 7/8/10 to invoice and AWB is packet correlation if the article is moving.
Definition and public “example” artefacts: EASA Form 1 example and definition. Packet: AOG customs packet.
Doana can extract the blocks from a PDF (Form 1 automation). It cannot sign, correct, or file the form.
