Gary Busey Accused of Knocking Woman Down at Airport

The woman -- named Carla Loeffler -- filed the lawsuit in L.A. County Superior Court, claiming she and Busey were waiting for the same flight at Tulsa airport back in May ... when Busey shouldered her without provocation.

According to Loeffler, Busey had been biding his time downing drinks at the airport ... and by the time their flight was called, he was completely faded.

Loeffler claims she was waiting in line on the jetway to board the flight -- and Busey barreled past her in an effort to cut the line, violently knocking her to the ground.
