What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) After landing and taxiing to parking sport, the Chino control tower noticed "flames" coming from the right engine. The tower notified the crew who immediately shutdown the engines and discharged the number two engine fire bottle before safely evacuating the aircraft. The fire department arrived to perform fire standby duties at the aircraft. There was no evidence of fire damage to the engine or cowling. The crew mentioned that they applied a "too rich" fuel/air mixture during taxi. This mixture caused the "burp" of flame to exit the exhaust. My investigation of the aircraft revealed no evidence of fire.
