## Discrepancy

MAINTENANCE AND REPAIR PROBLEM.DURING OVERHAUL OF A300-600 LANDING GEARS SHIPSETS IN SHOP, WE HAVE FIGURED OUT THAT PARTS REMOVED FROM TWO DIFFERENT GEARS HAVE BEEN EXCHANGED. THE DIFFERENCE IS ON THE BARREL PN C23135910-4. ONE OF THE BARREL IS WITH HOLE DIAMETER IN ACCORDANCE WITH STANDARD DIMENSION. THE SECOND BARREL IS DEIGNED WITH OVERSIZE HOLE DIMENSION. 

REVIMA HAS SUBMITTED A CONCESSION REQUEST TO THE TC HOLDER, TO CHECK IF THE NOSE LANDING GEAR ASSEMBLED WITH THE OVERSIZE HOLE DIMENSION CAN REMAIN IN OPERATION WITH THE PART.
