Airline spokesman James Faulkner said Tuesday that the landing gear was still working and the plane made a safe landing.
Faulkner says the pilot of the MD-80 jet declared an emergency but passengers weren't told to brace for a crash landing.
Flight 1862 was carrying 121 passengers and five crew members. The airline says passengers have been put on another plane for the trip to St. Louis.
