## Discrepancy

DURING LT PYLON ACCESS FOR ACB001, IT WAS NOTICED THAT THE LT ENIGNE UPPER AFT ENGINE MOUNT ANTI ROTATION DEVICE (FWD SIDE)  WAS ROTATED OUT OF POSITION. WITH A SLIGHT MANIPULATION OF THE  ENGINE MOUNT TVA (FWD SIDE) THE ANTI ROTATION DEVICE BECAME LOOSE WHICH THEN PRESENTED THE FWD AND AFT ENGINE MOUNT TVA'S TO BE LOOSE AND FREE TO MOVE.
