There is a source of up to date type specific maintenance programmes that have been in use for years... France.
EASA part M is based on the old French system which has long used the concept of 'controlled' & 'uncontrolled' environment.
All French registered & certified aircraft will have been maintained under an approved type specific programme. Under part M those programmes were simply adopted by EASA under a form of grandfather rights. So any CAMO which wishes to obtain a fully up to date type specific and equipment specific maintenance programme will find them in the files of OSAC. But of course they are written in French which is one of the EUs official languages. Seems fair enough to me, we make French pilots speak English, so now our engineers should fix aircraft using French programmes.
