## Discrepancy

MFG HAS COME OUT WITH A SB 78B, TO REPLACE THE MAIN AND AUX FUEL TANKS WITH BLADDER TYPE TANKS FOR THIS SERIES ROTORCRAFT.  HAVE NOTICED THAT AT THE FIRST INSPECTION FOLLOWING THE FUEL TANK MODIFICATION THA THE GASCOLATOR/AIR FRAME FUEL FILTER IS HALF COVERED WITH LINT.  SUBSEQUENT INSPECTIONS SHOW NO MORE SIGNS OF LINT CONTAMINATION.  HAVE HAD NO FUEL STARVATION ISSUES DUE TO THE LINT TO DATE.
