Commercial operation on an EASA AOC "on condition"

[Alexander Pichler]

Dear all,


I was wondering, if it is possible, to operate an aircraft (PA34) commercially on an EASA AOC whilst one engine would be on condition due to its 12 year time expiration?


However, the engine is not expired hours wise just calendar.


The other engine such as both propellers are within calendar and hours TBO.


Is this eventually possible under Austrian, German, Swiss, Luxembourg, Maltese, Guernsey, San Marino etc. registration?


Would appreciate your feedback.


Thanks,


Alex
