## Discrepancy

(CAN) DURING A 500HR INSPECTION THE NLG OLEO LEATHER SLEEVE LOWER METAL COLLAR WAS OBSERVED TO HAVE BECOME DISENGAGED FROM THE OLEO PISTON STEP AND APPEARED TO HAVE BEEN DISTORTED.  UPON FURTHER INSPECTION OF THE NLG OLEO, AFTER DISASSEMBLY, IT WAS ALSO DISCOVERED THAT THE INTERNAL ELASTOMERIC BEARING "BUMPER" HAD BECOME DETERIORATED AND BRITTLE, IT WAS ALSO DISCOVERED THAT THE PISTON BEARING LOWER RETAINER HAD A SPLIT IN 1 AREA, ALTHOUGH THE FRACTURE OF THE RETAINER WOULD NOT ALLOW THE BEARINGS TO ESCAPE THE RACEWAY.
