## Discrepancy

(CAN) NLG SHOCK STRUT ASSY PIVOT PIN FOUND BROKEN.  PIVOT PIN REPLACED IAW CMM 32-21-04. PIVOT PIN IS BEING RETURNED TO MFG FOR INSPECTION AND ANALYSIS INVESTIGATION.  NOTE: IT WAS NOT THE LARGE PIVOT PIN THAT BROKE BUT INSTEAD IS THE SMALLER BOLT RETAINING THE LOCK ARM SAFETY DEVICE THAT PREVENTS PIVOT PIN MIGRATION.
