## Discrepancy

FUEL LEAK ON RT WING BY WW.  REPLACED THE RT AFT BOX & NACELLE FUEL BLADDERS.  LEAK CHECKED OK.  ACFT WAS RETURNED TO SERVICE.  THIS SDR IS BEING SUBMITTED DUE TO A TREND OF NUMEROUS B300 WHEELS UP FLEET FUEL BLADDER LEAK REPORTS.  BELIEVES THAT THE LEAKING FUEL BLADDERS ARE THE RESULT OF A BAD BATCH FROM ONE MANUFACTURER.  THE REPLACEMENT FUEL BLADDERS ARE FROM A DIFFERENT MANUFACTURER HAVE BEEN RELIABLE.
