Some aeroplane types are explicitly excluded from the similar FAA rule (FAR 26.11(g)). Are these types also excluded from EASA requirements?

How can we as DOA identify if an aircraft model is applicable or otherwise has been made compliant (by means of a retroactive requirement) to this rule?

We anticipate that a CRI may be needed for each STC because of the need to at least have the applicants use the checklist. Has EASA considered the effect on the hours to be allocated for each task to include the extra work? In addition may this not also affect the classification of an STC from Simple to Standard because of the need to include an electrical specialist each time?

To avoid the extra workload would it not be an idea to have EU DOAs include consideration of the ICA requirements as part of their procedures? This would make EWIS part of their normal practises?

Will we need to amend the TC basis for each type to include this CS-25 requirement and publish in amended TCDSs?
