## Discrepancy

CLT - FLT 1722  FLL TO CLT.  A BURNING ODOR WAS NOTED WITH THE NUMBER ONE FORWARD EQUIPMENT FAN SELECTED ON, ALONG WITH AN EICAS MESSAGE "FWD EQUIP SUPPLY FAN 1".  THE ODOR DISSIPATED WHEN THE FAN WAS CHANGED TO ALTERNATE.  MAINTENANCE REPLACED THE FORWARD NUMBER ONE EQUIPMENT SUPPLY FAN.  OPERATIONALLY CHECKS OK.
