## Discrepancy

DURING NR 1 ENGINE CHANGE NOTICED THAT BOTH FORWARD ENGINE MOUNTS 65B90335-7 & -8 WERE LOOSE.  IT WAS REPORTED THAT AN APPROX .125 INCH SIDE TO SIDE MOTION RELATIVE TO THE ADJACENT WEB WAS POSSIBLE.  *S/D*  FITTING MOVEMENT DUE TO LOOSE FASTENERS.  UAL REPLACED FITTINGS WITH NEW FASTENERS.  UAL WILL CHECK OTHER 747-200 ACFT IN FLEET FOR SIMILAR CONDITION.
