Caution,
This is a game where precision with terms pays dividends.
There are no 'EASA Annex1' aircraft.
Instead:
There are 'EASA aircraft' & 'non-EASA Aircraft'.
Annex II (of the Basic Regulation) contains details of which aircraft are 'non-EASA'.
All the rest are 'EASA aircraft'.
Annex I of that regulation is about essential requirements for airworthiness.
