The Federal Aviation Administration says two flight attendants were injured when a Southwest Airlines pilot took sudden evasive action to avoid a collision with a private plane near Burbank over the weekend.

FAA spokesman Ian Gregor said Tuesday the pilot of Southwest Flight 2534 from Las Vegas got an automated alert because it was briefly on a collision course with another aircraft. The plane was flying at about 6,000 feet Saturday about 20 miles away from Bob Hope Airport.

Gregor says the Southwest pilot made some sudden maneuvers to avoid the other plane, which was about two miles away. He says one Southwest flight attendant suffered a broken shoulder, the other was bruised.

The FAA and National Transportation Safety Board are investigating the incident.
