This is a pretty bold statement considering the facts (none.)
Did shoddy mx cause the wheel to fall off?
Did pilot error cause the wheel to fall off?
Did a manufacturers defect cause the wheel to fall off?
Did bombardier get a bad set of hardware for the gears that was not casted correctly and was softer than normal causing a shear in some of the bolts?
Do you get where I am coming from with this?
Do not be so quick to fry a regional when there is no information. If it later comes out that mx failed to torque the wheel to specs and then incorrectly fastened the safety wire then you can revisit this post and blame the airline.
The amount of "incidents" that happen daily in the airline industry are numerous, Colgan obviously has a spotlight on it as of now so if they taxi out missing a seatbelt extender it will be all over the news.
