EASA Maintenance Release& CRS Software
Issue an EASA-compliant Certificate of Release to Service from the same platform that runs the work order. Two-stage sign-off, Part-145 and CAMO references, airworthiness limitations per M.A.801(e)(4), and full installed-part traceability — every release defensible the moment it is signed.
An EASA Release to Service Is a Document, a Signature, and a Chain of Evidence
Returning an aircraft to service under EASA rules is not a status toggle. A Certificate of Release to Service has to name the organisation that signed it — the Part-145 approval or the CAMO reference — list any airworthiness limitations and derogations under M.A.801(e)(4), and account for every part installed, including the Form 1 / 8130-3 certificate behind each one. Get one detail wrong and the release is not airworthy — it is a finding at the next audit.
Aviatize builds the certificate as the work happens. The work order already knows the tasks closed, the parts fitted and where each came from, and the technicians and inspectors who signed. When it is time to release, you sign the Maintenance Form Certificate to authorise the check flight, then issue the CRS — each as its own PDF, with the references snapshotted so the document can never drift from what was true at release. Signed certificates are locked; corrections go through an Amendment CRS. This is the continuing-airworthiness layer most flight school platforms do not have.
Everything an EASA Release Has to Carry — Built In
From the two-stage sign-off to part-level traceability, Aviatize produces a release document that stands up to a regulator's review.
Two-Stage Release Sign-Off
Sign the Maintenance Form Certificate to authorise the maintenance check flight, then issue the Certificate of Release to Service once the check flight is complete. Each stage produces its own signed PDF, and logbook entries stay pending until the final release is signed. Preview the in-progress certificate before you commit.
Part-145 & CAMO References
Configure your Part-145 approval reference and default maintenance location once — both appear on every CRS. Set a CAMO reference number and override the maintenance location per work order for cross-organisation traceability. Every reference value is snapshotted at release for legal immutability.
Limitations & Derogations (M.A.801(e)(4))
Record airworthiness limitations and derogations directly on the certificate. They are rendered on the CRS PDF exactly as EASA M.A.801(e)(4) requires, so the release document is complete and defensible the moment it is signed.
Next-Due Snapshot on Every CRS
The CRS PDF captures the next scheduled maintenance — date, hours, and cycles — as a snapshot at release time, giving the pilot an at-a-glance preview of when the aircraft is next due before they accept it.
Full Installed-Part Traceability
Every installed part carries its origin. A Source column on the CRS components table distinguishes customer-supplied parts from components cannibalized off another aircraft (for example, From PT-XYZ), so an inspector can see at a glance how each part arrived.
Component Cannibalization
Replace a part by cannibalizing it from a donor aircraft. Pick the donor and the matching installed component, and the swap writes logbook entries on both aircraft — each side of the history shows exactly where the part went.
Customer-Supplied Parts & WO Files
Every work order has a Files tab for photos, delivery notes, and customer paperwork. Customer-supplied parts require an EASA Form 1 / FAA 8130-3 to be uploaded before install, and that certificate is mirrored to the Files tab automatically.
Signed-CRS Immutability + Amendment CRS
Once signed, a Certificate of Release to Service cannot be deleted — the inspector signature and supporting items are preserved in the audit trail. Corrections are made through a formal Amendment CRS, never by overwriting the original.
Consolidated My Work for Certifying Staff
Technicians, inspectors, and independent inspectors open one My Work view that lists every work order with a task waiting for them, then act from a focused side panel with just the steps they need to take.
Fleet-Status Reports for Audits & Handovers
Aircraft and fleet status reports show maintenance state at a glance — next-due dates, remaining hours, and the top reminders per aircraft. Export to PDF for an external audit or an operator handover.
Why Maintenance Organisations Release on Aviatize
The release is generated from the live work order — not retyped into a separate document — so the certificate matches the maintenance that was actually performed.
Built for How Airworthiness Is Actually Organised
Whether you hold a Part-145 approval, manage a CAMO in-house, or work a mix of your own and customer aircraft, the release workflow adapts to you.
Part-145 Maintenance Organisations
Issue the CRS from the same system that holds the work order, the parts, and the technician hours. Your Part-145 reference prints on every certificate, customer-supplied-part certification is enforced before install, and the signed record is immutable for the regulator.
In-House CAMO & ATO Fleets
Flight schools and ATOs managing continuing airworthiness in-house get the CAMO reference on every release, next-due snapshots for their pilots, and fleet-status reports for the annual oversight audit — without leaving the platform that already runs scheduling, training, and billing.
Mixed In-House & Third-Party Work
Override the maintenance location per work order, track parts cannibalized between tails, and keep customer paperwork on the work order Files tab. The release document carries full traceability whether the aircraft is yours or a customer's.
The EASA release workflow is part of the wider Aviatize maintenance system — tracking, work orders, and parts inventory all feed the certificate.

Frequently asked questions
What is an EASA Certificate of Release to Service (CRS)?
A Certificate of Release to Service (CRS) is the document that returns an aircraft to airworthy status after maintenance under EASA rules. It identifies the approved organisation that performed and released the work — the Part-145 approval or CAMO reference — records any airworthiness limitations or derogations required by M.A.801(e)(4), and accounts for the parts installed. In Aviatize the CRS is generated directly from the work order, so the certificate reflects the tasks closed, the parts fitted, and the staff who signed, and exports as a PDF for the aircraft records.
How does the two-stage Maintenance Form Certificate sign-off work?
Aviatize splits the release into two signatures. First you sign the Maintenance Form Certificate (MFC), which authorises the maintenance check flight. After the check flight is complete, you issue the Certificate of Release to Service. Each stage produces its own signed PDF, and the logbook entries stay pending until the final release is signed — so an aircraft is never shown as released before the check flight has confirmed the work.
Where do the Part-145 and CAMO references appear on the release?
You configure your Part-145 approval reference and default maintenance location once in maintenance settings, and they print on every CRS. A CAMO reference number can also be set, and the maintenance location can be overridden per work order for cross-organisation work. Every reference value is snapshotted at the moment of release, so a certificate always shows the references that were valid when it was signed, even if the settings change later.
How does Aviatize handle customer-supplied parts and cannibalized components?
Customer-supplied parts must have an EASA Form 1 / FAA 8130-3 uploaded before they can be installed, and that certificate is mirrored to the work order's Files tab automatically. When a part is cannibalized from a donor aircraft, the swap writes logbook entries on both aircraft. The CRS components table then shows a Source column that marks each part as customer-supplied or cannibalized (for example, From PT-XYZ), so an inspector can trace how every installed part arrived.
Can a signed CRS be edited or deleted?
No. Once a Certificate of Release to Service is signed, Aviatize locks it — it cannot be deleted, which preserves the inspector signature and supporting items in the audit trail. If a signed certificate needs correcting, you issue a formal Amendment CRS rather than overwriting the original, keeping the full release history intact for audits.
Is the EASA Release to Service workflow available to every Aviatize operator?
Yes. The EASA Release to Service and CRS workflow is available to every Aviatize operator. You can move your whole fleet to the digital release workflow or switch aircraft over one tail at a time, so adoption fits the way your maintenance organisation works. The same platform also runs scheduling, training, billing, and parts inventory, so the release connects to the rest of your operation rather than living in a separate system.
