## Discrepancy

NOSE GEAR COLLAPSED ON LANDING.  FOUND NOSE GEAR PIVET BOLT FOR DOWNLOCK, PN 502-341 BENT. PN 86275-03, DOWNLOCK MAY BE BENT.  THIS PART INCLUDES THE HOOK.  THE LEVER ON DOWNLOCK MICROSWITCH, PN 86409-02 WAS BENT WHEN GEAR RETRACTED.  BELIEVE THAT WAS THE REASON THEY HAD 3 GREEN BEFORE LANDING.  SUSPECT A HARD LANDING PRIOR OF THE INCIDENT.  RECOMMEND TO INSPECT GEAR AND DOWNLOCKS AFTER EACH HARD LANDING.
