An O-ring was severed when being installed on a fuel tube during maintenance. The damage degraded the O-ring sealing function at the right engine FFT-to-fuel OUT tube flange. During the next takeoff, high-pressure fuel flowed past the damaged seal and sprayed into the engine core compartment. The fuel contacted hot engine surfaces and ignited. The right nacelle fire detection system detected the fire and a right engine fire warning alerted in the cockpit. The flight crew shut down the right engine, which cut off the engine fuel supply. The fire extinguished after the fuel supply was stopped. The fire damaged the right engine external components and burned through the right nacelle inboard core cowl.
Probable Cause: Maintenance personnel's failure to ensure proper installation of a fuel tube O-ring, which resulted in an undercowl engine fire during initial climb.
