Narrative:

I made a landing at the minneapolis flying cloud airport carrying approximately less than a half inch of rime ice on the leading edge of the pneumatic deicing boots on the wings and horizontal and vertical stabilizer. I did not activate the boots after picking up the ice between 2500 and 3000 ft AGL as I was making a normal stabilized approach and did not want to disrupt my descent profile. I crossed the fence at about 90 KTS IAS, the crosswind component was 7 KTS, and landed. At touchdown, everything seemed normal and as the main gear touched down and the nose dropped, the aircraft lurched, the nose gear retracted and the aircraft came to a stop on the runway.

Title: NOSE GEAR COLLAPSED AFTER LNDG WITH A LOAD OF AIRFRAME ICE.

Narrative: I MADE A LNDG AT THE MINNEAPOLIS FLYING CLOUD ARPT CARRYING APPROX LESS THAN A HALF INCH OF RIME ICE ON THE LEADING EDGE OF THE PNEUMATIC DEICING BOOTS ON THE WINGS AND HORIZ AND VERT STABILIZER. I DID NOT ACTIVATE THE BOOTS AFTER PICKING UP THE ICE BTWN 2500 AND 3000 FT AGL AS I WAS MAKING A NORMAL STABILIZED APCH AND DID NOT WANT TO DISRUPT MY DSCNT PROFILE. I CROSSED THE FENCE AT ABOUT 90 KTS IAS, THE XWIND COMPONENT WAS 7 KTS, AND LANDED. AT TOUCHDOWN, EVERYTHING SEEMED NORMAL AND AS THE MAIN GEAR TOUCHED DOWN AND THE NOSE DROPPED, THE ACFT LURCHED, THE NOSE GEAR RETRACTED AND THE ACFT CAME TO A STOP ON THE RWY.
