## Discrepancy

(CAN) A FRESH D-CHECKED GEAR LEG (RT) WAS TO BE INSTALLED ON ACFT.  WHEN ATTEMPTING TO MOUNT THE LWR PLATE ASSY TO THE GEAR LEG, IT WAS FOUND THAT 3 OF THE 4 MOUNT HOLES HAD IMPROPERLY INSTALLED HELI-COILS.  WHILE ATTEMPTING TO INSTALL BOLTS, THESE HELI-COILS WOULD WIND OUT OF THEIR RESPECTIVE HOLES. NEW HELI-COILS WERE THEN INSTALLED.
