I was approaching grass valley airport after flying for about one hour without incident. The aircraft contacted the runway at grass valley unexpectedly in a slightly lateral motion after a fully stabilized approach. I elected to go around; the left gear light remained on and I decided to proceed to sacramento executive airport to verify gear problem by tower inspection. After cycling gear several times with fly by tower it was determined that the left gear remained dangling and unlocked. I executed a smooth low speed landing but the left gear collapsed in the final 10 seconds of roll out. Damage was minimal and limited to the left propeller, left landing gear and left flap. Cause of this incident was landing gear malfunction. Supplemental information from acn 87373. Aircraft contacted runway at grass valley unexpectedly sideways after fully stabilized approach.

Title: GA SMA DAMAGED LNDG GEAR LNDG AT 017 THEN MADE GO AROUND AND RETURNED TO SAC WHERE DAMAGED GEAR COLLAPSED.
Narrative: I WAS APCHING GRASS VALLEY ARPT AFTER FLYING FOR ABOUT ONE HOUR WITHOUT INCIDENT. THE ACFT CONTACTED THE RWY AT GRASS VALLEY UNEXPECTEDLY IN A SLIGHTLY LATERAL MOTION AFTER A FULLY STABILIZED APCH. I ELECTED TO GO AROUND; THE L GEAR LIGHT REMAINED ON AND I DECIDED TO PROCEED TO SACRAMENTO EXECUTIVE ARPT TO VERIFY GEAR PROB BY TWR INSPECTION. AFTER CYCLING GEAR SEVERAL TIMES WITH FLY BY TWR IT WAS DETERMINED THAT THE L GEAR REMAINED DANGLING AND UNLOCKED. I EXECUTED A SMOOTH LOW SPD LNDG BUT THE L GEAR COLLAPSED IN THE FINAL 10 SECONDS OF ROLL OUT. DAMAGE WAS MINIMAL AND LIMITED TO THE L PROP, L LNDG GEAR AND L FLAP. CAUSE OF THIS INCIDENT WAS LNDG GEAR MALFUNCTION. SUPPLEMENTAL INFO FROM ACN 87373. ACFT CONTACTED RWY AT GRASS VALLEY UNEXPECTEDLY SIDEWAYS AFTER FULLY STABILIZED APCH.
