Sofema Aviation Services (SAS) www.sassofia.com considers roles, responsibilities & best practice
Introduction
In accordance with EASA Part 145 the Aircraft Maintenance Organisation (AMO) is responsible to perform the “work” in accordance with approved documentation using approved material and to release on completion In Accordance with the requirements of EASA Part 145.A.50 Certificate of Release to Service (CRS).
Workscope Considerations:
- Component Service Bulletins
o Service Bulletins are not mandatory – however, for multiple reasons is sensible – even best practice to consider performing SB’s when the opportunity presents. But note the “owner” should concur with the requirement often after a combination risk assessment / return on expenditure analysis.
- Findings during the initial assessment
o It is possible that findings may result in the component being beyond economical repair (BER) so it is important to have established communication protocols with the customer to ensure effective and documented decision making takes place.
o To release a component with a CRS means that the component is fully compliant with assessment / test / inspection criteria – therefore any defect which impacts this will prevent a CRS from being issued. (again appropriate communications)
o How to establish customer acceptance?
– Multiple ways including a signature of acceptance.
– Issue an Engineering Order (Controlled Document) or similar to reference the task.

What Constitutes Approved Data
Approved data is data that the FAA / EASA has approved and is usually identified as such.
Approved data includes:
- Type certificate data and specification sheets,
- Supplemental type certificates (STC),
- Airworthiness Directives (AD),
- Manufacturer’s approved data under a DOA, (AMM / SRM / CMM, etc)
- FAA Designated Engineering Representative (DER) data (Note & Consider Several differences between FAA & EASA – PMA / TSO.
