212 man,
I think you're right the DOCs on a Dash 8 should be minimal, but if the aircraft were leased on a rip-off contract that ensured that almost all of the profit on it went to a certain company in Holland, (then on top of that a monthly fee to the lessors), I guess it could become more marginal. I wouldn't be a bit surprised if most of the spares were also purchased from a certain company in Holland too, rather than from Canada.
