The DC-10 is already certified in Canada as Canadian airlines flew it. As for crew and maintenance there is a wealth of ex-DC-10 mintenance and crew around. I know many people who have flown the 10 worked on it and endorsed on it. As well MTU in YVR do CF6-50 eng overhaul and maintenance. There is also room for maintenance to be done in YYZ with that new enormous hangar. I hear they are renting the bays out for nothing since AC backed out of the deal. Westjet has snapped up one bay at amazing rates and has options on another. I for one am happy to see things are looking up for work and the airline industry. Let's hope it lasts more than a couple of years. ACE also has some Capt's with heavy experience as well.
