The restriction is on the AOC, not the aircraft. So, looking at the earlier post regarding flying the aircraft out of the country, that ought not to be an insurmountably difficult exercise, I shouldn't have thought.
Interestingly, the preliminary ATSB investigation report into the MEL incident, just to hand at
this site indicates that, while the crew misread the paper plate, the FMS database contained an incorrect level to which they subsequently descended.
Doesn't excuse the error, but alters the complexion somewhat, I would have thought ?
