FORT WAYNE, Ind. (AP) — The director of operations at the Fort Wayne airport says an inspection of an Allegiant Air plane that made an emergency landing there after a fire warning light went on shows no sign of a fire.

Craig Williams says a search of the cargo bay Friday night showed no sign of smoke or fire and officials don’t know what caused a cargo fire indicator light to turn on, leading to the emergency landing.

Allegiant Air spokeswoman Jessica Wheeler says the flight from South Bend to Punta Gorda, Florida landed in Fort Wayne shortly before 1:30 p.m. All 149 passengers and five crew members were safely evacuated.

Wheeler says a replacement plane was headed to Fort Wayne from Bellingham, Washington near Seattle.
