Russia violates NATO airspace repeatedly with attack aircraft.
Does this invoke article 5?
For all practical purposes, article 5 is invoked by member governments, not by Russian provocations. After such an event, they would confer and decide what, if any, action becomes necessary to "to restore and maintain the security of the North Atlantic area." It is conceivable that serious provocations trigger a chain of events which lead to "action as [the member states] deem[s] necessary, including the use of armed force," but this would be based on a more comprehensive judgement than the mere fact of overflights taking place.
The apparent purpose of Russian provocations is to distract Western countries from giving aid to Ukraine. By now, it would be newsworthy if no Kremlin spokesperson threatens nuclear war on a given day, so they have to escalate their provocations.
