For Rolls. Royce engines where the SoD is Germany, and the SoM is the UK, the organisational interfaces for data access and cooperation in continuing airworthiness matters between design and production are satisfied by common systems applied by RR and RRD, under the global Rolls-Royce corporate structure. The acceptability of these design- production links is a key element of the award of the EASA Design Organisation Approval (DOA) held by RRD, which combines RRD and RR design activities, and the UK CAA Production Organisation Approval (POA) and the EASA POA held by RR, both of which will continue to apply after December 31, 2020. The aforementioned approvals assure the reporting of issues relevant to continued airworthiness to the SoD and the SoM. The requirement to ensure the necessary arrangements are in place are set out in Part 21.A.133(c), which is a rule common to both Germany’s and the UK’s legal system. Part 21.A.133(c)’s interpretation and applicability is the same in both States.
