## Discrepancy

REPEATED ELECTRICAL POWER AND SUPPLY PROBLEMS WITH THIS AIRCRAFT REVEALED A LOOSE GALLEY GROUND WIRE CONNECTION.  FURTHER INVESTIGATION FOUND INDICATIONS OF ARCING AND FIRE/SMOKE DAMAGE.  *S/D*  DISCOVERED WIRE W3666000410 WAS NOT CONNECTED SECURELY TO  AIRCRAFT GROUND.  WIRE WAS INSTALLED ON THE TERMINAL WITHOUT A RETAINING NUT.  ALSO, A NEW DELIVERED AIRCRAFT WAS RECEIVED IN SIMILAR CONDITION.  REPLACED WIRE AND CORRECTED DAMAGE, OPERATION CHECKS NORMAL.
