## Discrepancy

BOTH PROPS OVERHAULED ON 1-20-96 TO C/W AD 95-24-05, SB 209, SL 1993-11-OIL FILL-AT OVERHAUL.  ALL 6 DE-ICER BOOT LEADS REPLACED.

AFTER APPROXIMATELY 20 HRS OPERATION, ALL 6 CLAMPS BROKE AT FLANGE BOLT HOLE AREA.  REPLACED ALL 6 CLAMPS WITH LIKE PART AND THEY AGAIN BROKE AT APPROXIMATELY 4 HRS.  AFTER REPLACEMENT, APPEARS NEW CABLE IS HEAVIER THAN ORIGINAL AND CENTRIFUGAL FORCE IS CRACKING ORIGINAL CLAMPS.  CURRENTLY REPLACING ORIGINAL ALUMINUM ADEL CLAMPS WITH STAINLESS STEEL ADEL CLAMPS.
