Narrative:
As aircraft come out of storage; circuit breakers and systems have not been reactivated correctly causing numerous rejected takeoffs or return to airfields.I suggest a task card or work assignment on an aircraft coming out of storage as a last item before aircraft release depicting a graphic of that fleet specific circuit breaker panels and an instruction to visually check all circuit breaker's to be pushed in except those that are deferred etc. Also a CAT 3 check should be assigned which could capture most system failures due to improper reactivation. Best prevention would include a high power runup.
