Aircraft
Started up the right engine and as I began to lean the mixture to stabilize the engine I heard a loud bang from the area of the right wing. As I looked out the right window of the cockpit I could see the wing had been severely damaged with flames coming out. I had not yet started the other engine and the airplane had not moved from its original position. After seeing the flames I immediately shut off the mixture to that engine and evacuated using the crew hatch. Once I was a safe distance away I call 911 to get the fire department and then notified supervisors.
Pilot reported evacuating the aircraft after the right engine failed and caught fire during start  up.
