WASHINGTON, June 11 (Reuters) - U.S. Transportation

Secretary Sean Duffy said on Wednesday he supports an

independent audit into airspace operations and safety oversight

in the Washington, D.C., region after a January 29 fatal

collision between an American Airlines ( AAL ) regional

passenger jet and an Army helicopter killed 67 people.

On Monday, two dozen U.S. senators asked the inspector

generals for the Pentagon and the Transportation Department to

open audits in response to the collision and ongoing

coordination issues between the Army and air traffic control at

Reagan Washington National Airport, following the collision and

a serious close call on May 1.
