KNOXVILLE, Tenn (WVLT) -- A Nashville-bound USAIR Express regional jet diverted to Knoxville's McGhee Tyson Airport has landed safely.
USAIR Express flight 2489 landed around 3:20 p.m. local time according to McGhee Tyson Airport spokesperson Becky Huckaby.
Surrounding rescue personnel and fire departments were put on an alert two status, a code meaning a plane is inbound with a potential problem.
They were released shortly after the plane landed.
Sources tell Volunteer TV news the pilot had radioed of a possible hydraulic problem, but a USAIR spokesperson wouldn't confirm that, saying it was too early to know the nature of the problem.
The spokesperson did say the plane was unable to make it to the gate under it's own power.
Passengers had to be bussed to the terminal and USAIR has arranged for bus transportation to take them on to Nashville.
The flight is operated by PSA Airlines, doing business as USAIR Express. The CRJ-200 regional jet had 40 passengers and three crew members on board, according to Huckaby.
Flight 2489 had departed Washington D.C.'s Reagan National Airport just before 2 p.m.
