Easa Stc
Lees' EASA STCs don't cover the PA30 or PA31. EASA aren't like the FAA so don't allow multiple aircraft types on a single STC - you can stretch it a bit to maybe all of the Cessna single-engined range, but not more than that. The PA31 can't be approved yet as the Class 3 version of the Aspen doesn't have EASA ETSO.
Lees currently have the following approved for Aspen:
PA28, 32, 34
C182
R112/114
and for Garmin G500/600:
PA23, 28, 32, 34, 44
R112/114
Beech 33, 35, 36, 55, 58
In progress: Robin DR300/400/500.
