LITTLE ROCK, Ark. — A Southwest Airlines flight ultimately headed for Baltimore landed safely at Little Rock National Airport after malfunctioning equipment caused a spark and some smoke in the cockpit.

Southwest Airlines spokesman Chris Mainz says airport emergency officials were alerted about 12:25 p.m. Wednesday after a small spark occurred in an overhead light fixture on Flight 871.

Mainz says the malfunction caused some smoke in the cockpit, and a fire extinguisher was used as a precaution.

He says the plane landed safely and no injuries were reported to the 103 passengers and crew members on board.

The flight was en route from Dallas, and was scheduled to stop in Little Rock before continuing to Baltimore.

Mainz says the plane was taken out of service and another aircraft was used to fly passengers to Maryland. — The Associated Press
