It depends on what they service. If they focus on corporate jets and
larger airplanes and the few new designs such as Cirrus, they might

Except that newer aircraft are less likely to require maintenance than
older aircraft.

All aircraft require maintenance. If you are flying them, you are
stressing them, and if you are not flying them, some components become
unreliable. See the annual inspection requirements as a starting point.
