The number of passengers suing American Airlines over an engine fire in March is now at 17, attorneys for those plaintiffs say. The fire happened aboard a Boeing 737 that had taken off from Colorado Springs en route to Dallas.

Part of the plane’s landing gear caught on fire during its departure from Denver International Airport on Saturday, according to Denver7’s reporting. The Miami-bound American Airlines flight 3023 reported a “maintenance issue” with an airplane tire about 2:45 p.m. and aborted takeoff, airline and federal officials said.

A small fire in the brake system just ahead of the jet’s takeoff prompted the evacuation of 173 passengers and six crew members, the authorities said.
