It is my understanding that the newer Q400's have a redesigned landing gear?
As for the report, it is not conclusive. Yet. So all of you jumping to conclusions based on "could", "possible" and "unknowingly", are doing the same error as the people you are poining your fingers at.
Introducing a new Q400 would take a lot of
PR, but the old one was as dead as a rotten fish after three accidents due to unsafe landing gear, at least as far as the majority of the Scandinavian pax were concerned. CPR on a rotten fish is pretty much pointless.
SAS is pretty much the same as everyone else out there. Inhouse maintenance is a thing of the past. Outsourcing is the name of the game.
Money, money, money. Or so they think.
