WASHINGTON, June 11 (Reuters) - The U.S. Army will

curtail VIP military helicopter flights around the Pentagon

after safety concerns were raised following the January 29 fatal

collision of a Black Hawk helicopter with an American Airlines ( AAL )

passenger jet near Reagan airport, a senator said on

Wednesday.

The Federal Aviation Administration in early May barred the

Army from training or priority transport flights after a May 1

close call and is currently negotiating a memorandum with the

Army to govern future military flights near commercial planes.

Senator Jerry Moran, a Republican who chairs an aviation

subcommittee, told reporters that the Army will limit training

missions near Reagan Washington National Airport and limit the

number of senior military and defense officials who can use

helicopters for transport.
