## Discrepancy

DOWNLOCK ACTUATORS COULD NOT BE RIGGED TO SPEC DURING ANNUAL INSPECTION CHECK.  FOUND ROD STICKING.  SENT IN FOR OVERHAUL, FOUND INTERNAL P/N 1280246-1 CRACKED AND P/N 1280120-3 DEEP SCRATCH.  UNIT CONSIDERED B.B.R. (17 YRS OLD).  REPLACED WITH OVERHAULED EXCHANGE UNIT.  PART SHOULD HAVE LIFE/LIMIT OVERHAUL TIME.
