## Discrepancy

FLT NR 0219 - EWR - THE GPWS SOUNDED AT 300 FEET WITH FLAPS SET AT 30 DEGREES WHILE ON APPROACH TO EWR.  A 'GO AROUND' WAS PERFORMED AND ON THE NEXT APPROACH THERE WAS NO GPWS WARNING WITH THE SAME CONDITIONS.  THE GPWS COMPUTER WAS REMOVED AND REPLACED IAW MM 34-52-11 AND SYSTEM OPERATION CHECKED GOOD.  (M)
