Sharp end
You are correct that an annex 2 aircraft administered by the UK CAA does permit an appropriately licensed engineer to issue an “A” conditions ferry permit.
EASA has a much more expensive and involved process for annex 1 aircraft involving issuing a ferry permit and subject to an engineers inspection.
If this was a brexit debate it would be a perfect example of the EU making things far more expensive by producing lots of paperwork that fails in any way to enhance safety.
