The first one concerns a runway overrun of an RJ CL600.
"There were no injuries among the three crewmembers and 49 passengers (including 3 lap-held children). The airplane was substantially damaged."
"Substantial damage" probably makes this an accident (although one can't be sure without knowing the exact nature of the damage; e.g. a contained engine failure would be considered an incident, even if the engine itself was substantially damaged).
The second one is about a Beechcraft 400A which lost power on both engines.
"After landing, the aircraft rolled off of the runway onto a taxiway, and the right landing gear tire deflated. [...] The two pilots on board were not injured."
I too would rate this an incident, based on the given information (probably a "serious incident", i.e "an incident involving circumstances indicating that an accident nearly occurred" - Annex 13). However, if the deflated tire would have caused secondary damage to e.g. the landing gear, wing, or airframe structure, it could be an "accident", depending on the nature of the damage.
