EASA to FAA transitions
Authorized release certificates review for an EASA to FAA transfer
Component release paperwork is the first thing a US-side reviewer pulls when an EASA-registered aircraft heads for the FAA register. This review works through the component release file, EASA Form 1 certificates, dual releases issued under the bilateral, FAA Form 8130-3s from earlier US history, and the installation entries that tie each certificate to the aircraft, and identifies which parts will raise conformity questions. It runs during transition preparation, before the records go to the buyer or the FAA-side reviewer. It delivers a release-document evidence map, a gap list, and requests for the certificates that need recovering or reissuing.
When this review is needed
- A US buyer's records auditor has started sampling the component file and asking about single-release Form 1 certificates.
- Parts were fitted by European maintenance organizations whose releases predate or sit outside dual-release arrangements.
- The component file mixes Form 1, 8130-3, and older national certificates across a long operating history.
- N-registration is planned on a fixed date and the release file is the least-reviewed part of the package.
The problem
A component file built up under EASA maintenance looks uniform until it is read with US acceptance rules in mind. Releases issued by organizations without FAA approval, Form 1 certificates issued for return to service in the EU system, and blocks completed in ways the US side reads differently all pass European reviews and then surface as questions during the FAA-side audit. The records team ends up defending certificate wording part by part with the delivery date already set.
What gets reviewed
- The component release file inventoried against installed rotables and recent removals
- EASA Form 1 certificates classified by issuing-organization approval status and release type
- Dual-release certificates verified for correct completion under the applicable maintenance annex guidance
- Legacy 8130-3 and prior national releases evaluated for continuity through the aircraft's EASA period
- Installation entries linking each certificate to a position, date, and work order on this aircraft
- New-part documentation from production organizations checked for acceptance on the US side

Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- Sampled installed parts trace to a release certificate acceptable in the FAA system, or are flagged with the reason they are not
- Dual releases carry both regulatory references and are completed consistently with the guidance in force at issue
- Certificate part and serial numbers match the installation record and the current status of the position
- Issuing organizations held the relevant approvals on the certificate date, checked rather than presumed
- No installed serialized part depends solely on a packing slip or a commercial certificate of conformity
Evidence normally required
- Component release file: Form 1, 8130-3, dual-release, and legacy certificates
- Rotable status list and removal and installation history
- Work orders and logbook entries covering component changes
- Approvals information for the maintenance and production organizations that issued releases
- Any prior audit findings on the component file
Common discrepancies
- Single-release Form 1 certificates from organizations without FAA approval, installed during EU-only operation
- Dual releases with one regulatory reference blank or an inconsistent release-status block
- Installation entries that cannot be matched to any certificate in the file for that serial number
- New parts delivered on production paperwork the US reviewer will question for lack of an acceptable release form
What is at stake
Parts whose release the US side will not accept generate hard choices late: source replacement paperwork from the issuing organization, replace the part, or accept a discounted position in the transaction. The registration and airworthiness certificate work can proceed while questions remain, but buyers and their auditors price unresolved release items, and a thin release file invites broad sampling that finds more.
How the work runs
Inventory the file
Index every release certificate against the rotable status and installation history.
Classify by acceptance route
Sort certificates into acceptable, dual-release, and problem categories under US rules.
Trace the problem parts
For flagged items, establish what alternative evidence exists and what must be requested or replaced.
Deliver map and requests
Hand over the evidence map, ranked gaps, and certificate requests to the issuing organizations.
What the buyer receives
- A release-document evidence map covering installed rotables and high-value components
- A gap list separating recoverable paperwork from parts needing replacement or negotiation
- Document requests to issuing shops and prior operators for missing or corrected certificates
Who uses the output
- Records teams preparing the file for the buyer's audit and N-registration
- Asset managers pricing and negotiating unresolved component items
- The incoming US operator's records organization setting up its system
How the work fits into the transaction or program
The release file underpins both the LLP trace and the equipment reviews in an EASA to FAA transition, since the same certificates serve as trace and as configuration evidence. Running the release review first lets those strands reuse its findings, and its request set is usually the longest lead item in the transition.

Jurisdiction-specific considerations
Acceptance of maintenance releases between the EU and US systems runs through the bilateral agreement and its maintenance annex guidance, which is what makes dual releases possible and defines their completion. Outside that framework, a Form 1 issued for return to service by an EU-only organization has no automatic standing in the FAA system, while US expectations trace to 14 CFR Part 43 and FAA Order 8130.21 practices for the 8130-3. The review applies the acceptance rules as they stood at each certificate's date and as the receiving reviewer applies them now.
Regulatory limits
This is a documentation review. It does not issue, reissue, or validate any release certificate, does not determine part eligibility for installation, does not approve suspected-parts dispositions, and does not make airworthiness determinations. Decisions about accepting parts and records remain with the certificating and receiving parties.
What this review does not cover
- Physical part inspection or dataplate verification on the aircraft
- Procurement of replacement parts or exchange units
- Suspected unapproved parts investigation beyond flagging the indicators
Specific to this review
- The date on a certificate matters twice: the issuing organization's approvals are checked as of issue, and the acceptance rules are applied as of the transition. A certificate can pass one test and fail the other.
- Dual releases fail on completion detail more often than on entitlement; a missing second regulatory reference costs the certificate its dual status regardless of the issuer's approvals.
- US-side auditors sample the release file by value and criticality, so settling landing gear, avionics units, and high-value rotables first removes most of the negotiating exposure.
- A part installed during a previous period of US operation may already have an 8130-3 buried in the historical file, which is cheaper to find than a reissued certificate is to obtain.

Frequently asked questions
Are EASA Form 1 certificates simply invalid on the FAA register?
No. A Form 1 issued as a dual release under the bilateral, correctly completed, is acceptable. The questions concentrate on single-release Form 1 certificates from organizations without FAA approval and on completion errors in dual releases. The review's job is to separate those populations before an auditor does.
