## Discrepancy

FLT 450 SJU-SXM, AIR TURNBACK DUE TO JUST AFTER TAKEOFF, BLEED 2 STARTED FLUCTUATING FROM 2 TO 118 PSI WITH NR 1 ENGINE BLEED ON MEL.  CREW PERFORMED QRH BLEED FAIL RESET, BLEED 2 CONTINUED TO FLUCTUATE.  AFTER RESET FOR 3-5 MINUTES THEN STABILIZED AT 45 PSI DURING THE REMAINDER OF THE FLIGHT.  FLUCTUATED AGAIN AT LEAST TWICE.  REMOVED AND REPLACED FAN AIR VALVE PER AMM 36-11-09-04.  OPS CHECK GOOD.
