THE PLT STATED THAT THE GEAR INDICATED DOWN AND LOCKED PRIOR TO LANDING AND DURING THE FIRST PART OF THE LANDING ROLL. AFTER ABOUT 1,000 FT OF ROLL THE PLT GOT AN UNSAFE INDICATION AND THE LEFT WING BEGAN TO SETTLE. AFTER THE LEFT GEAR COLLAPSED THE ACFT SWERVED TO THE LEFT OFF THE RWY. THE BOLT, P/N NAS464P4-26, WHICH ATTACHES THE BELLCRANK, PN 5041001-1, TO THE STRUT WAS SHEARED AND ONE SIDE OF THE CLEVIS AT THE LOWER END OF THE BELLCRANK. BOTH OF THESE BROKEN COMPONENTS COULD BE ASSOCIATED WITH OVERLOAD CONDITIONS INDUCED WHEN THE GEAR COLLAPSED AND NEITHER SHOWED EVIDENCE OF PREVIOUS DAMAGE. THERE WAS NO EVIDENCE OF A HARD LANDING. THE LANDING GEAR COMPONENTS APPEARED TO HAVE ADEQUATE LUBRICATION. DUE TO IMPACT DAMAGE THE RIGGING OF THE RETRACTION LINKAGE PRIOR TO THE ACCIDENT COULD NOT BE DETERMINED.
