## Discrepancy

(AUS) RIGHT MAIN LANDING GEAR ATTACHMENT BOLT SHEARED.  MLG STRUT ROTATED IN ITS HOUSING AND THEN COLLAPSED. BOLT SHEARED DURING LANDING WHEN THE AIRCRAFT STRUCK A PILE OF GRAVEL.  SUSPECT BOLT HAD ALREADY BEEN DAMAGED ALLOWING IT TO EASILY SHEAR WITHOUT CAUSING DAMAGE TO THE ATTACHMENT STRUCTURE.
