A SkyWest operated Bombardier CL600 passenger jet, flying for United Express, caught fire after landing at Denver International Airport (DIA), Colorado, 2nd July.
More than 63 people on board, passengers and crew, escaped without injury. The fire in one of the two engines mounted on the rear of the aircraft body was successfully extinguished by the airport fire services. The plane had just completed a one hour flight from Aspen. A preliminary report to the Federal Aviation Authority suggests that a tire fire on landing spread to the engine. Aviation applies extremely tight fire safety requirements to all materials, despite widespread use of polymers to achieve lower weight.
