## Discrepancy

AT TOUCHDOWN THE LT MAIN GEAR DID NOT LOCK OVER CTR RESULTING IN THE LT GEAR RETRACTING, PROP STRIKE AND DAMAGE TO LT TIP FUEL TANK.  APPEARS BOLT (NAS464P4-26) AND SPACER (S133-4P32) THAT ATTACHES BELLCRANK (5041001-11) TO LT GEAR ASSY UPPER TRUNNION BROKE RESULTING IN BELLCRANK BREAKING AND GEAR NOT LOCKING OVER CENTER.  RECOMMEND INSP AND REPLACEMENT OF ATTACH HARDWARE.
