The arrest of an F.A.A. employee on assault and battery charges comes as flight operations at the airport have been under scrutiny since a passenger jet and an Army helicopter collided in January.

A Federal Aviation Administration employee working at Ronald Reagan Washington National Airport outside of Washington, D.C., was recently charged over a workplace altercation, authorities said.

Ronald Reagan National Airport was the scene of a recent near miss and control tower brawl, more than two months after a collision killed 67 people.
