## Discrepancy

PURCHASED 2 NEW NOSE LANDING GEAR CYLINDER ASSEMBLYS WITH INCORRECTLY MACHINED CENTER BORE.  THE BORE OF THE CYLINDERS IS TOO SMALL AT THE TOP WHICH DOESN`T ALLOW UPPER GEARINGS FULL TRAVEL TO TOP OF CYLINDER.  THE COULD CAUSE BEARING TO FAM IN BORE AND LANDING GEAR TO MALFUNCTION ON RETRACTION/ EXTENSION.  (K)
