ARLINGTON, Va. (AP) - US Airways is investigating why flames were seen coming from the engine of an airplane as it landed at Reagan National Airport outside Washington.

US Airways spokeswoman Valerie Wunder says the captain of flight 1764 from Charlotte, N.C., to Washington declared an emergency as a precaution upon landing around 7 p.m. Saturday. Wunder says flames were seen coming from the Airbus 319's engine, but it does not appear that the engine was on fire. No one on board was injured.       

Metropolitan Washington Airports Authority spokesman Rob Yingling says by the time firefighters arrived, there were no flames. The plane taxied safely to the gate on one engine about five minutes later.
Wunder says US Airways mechanics are investigating the problem.
