## Discrepancy

IN FLIGHT THE NR 2 FUEL TANK TEMPERATURE WAS ABOVE RED LINE ON THE GAUGE.  THE TEMPERATURE DROPPED WHEN PULLING POWER BACK OR SELECTING AUXILIARY PUMP.  THERE WAS A REPORT OF SMELLING BURNT POPCORN IN THE CABIN AREA.  WHEN 934HA WAS IN ROA THE FUEL/OIL WAS REMOVED AND REPLACED FIXING THE HIGH TEMPERATURE PROBLEM.  ALSO THE RIGHT HAND BLEED PIPE ASSEMBLY WAS REPLACED WITH NO FURTHER SMELLS OF  BURNT POPCORN.
