I think you're right. When looking up "crash" with the NTSB web site I get bounced to "accident". The Canadian TSB doesn't address the word "crash".
In the absense of a definition, I guess it's left to anyone's interpretation. We cant really deem someone to be wrong or right.
In the case of Skyservice, the plane did collide with something. It hit the ground. That's what caused the damage to the plane, and some less sturdy passengers, experiencing different levels of force across the length of the plane as they were levered up and down.
