NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
During the climb-out, a 15% decrease in the right eng epr was noted by the flt crew. This was followed by a loud bang & failure of the #2 eng. The #2 eng was shut down & the acft was flown back to the departure arpt. An initial exam revealed that the right eng top cowling had separated & the lower section of the combustion case was split. Eng removal & teardown revealed the #5 fuel nozzle nut lock ring was mis-assembled. This detracted from the torque on the fuel nozzle nut & inadequately compressed the #5 fuel nozzle seal. Subsequently, the fuel nozzle leaked & allowed local overtemp of the outer combustion chamber case at the 6 o'clock position.
