Narrative:

After conducting a thorough preflight and WX brief I took off from anoka country for st paul airport. All system appeared normal. I monitored ATIS and contacted the checklist, confirming gear down (3 green) with a visibility confirmation in the nacelle mirror. Approach was normal with proper airspeed. There was no indication of problems as I reduced the throttle prior to T/D. I touched the mains first and lowered the nose. The nose gear collapsed (never accepting the aircraft's weight). As the nose dropped, the propellers struck. I went through emergency procedures; shutting down the engines using the mixture and fuel lines. I also shut down the fuel pump and electrical master. After clearing the aircraft from the runway I contacted our director of operations (per operations manual), and met with GADO officers. One week prior to this incident the nose strut actuator was removed, rebuilt and reinstalled. The aircraft had flown once prior to this incident west/O problems. I don't know what more I could have done but I have consulted more experienced airmen.

Title: SMA, ON SECOND FLT ATER LNDG GEAR OVERHAUL, EXPERIENCES NOSE GEAR COLLAPSE ON TOUCHDOWN.

Narrative: AFTER CONDUCTING A THOROUGH PREFLT AND WX BRIEF I TOOK OFF FROM ANOKA COUNTRY FOR ST PAUL ARPT. ALL SYS APPEARED NORMAL. I MONITORED ATIS AND CONTACTED THE CHKLIST, CONFIRMING GEAR DOWN (3 GREEN) WITH A VIS CONFIRMATION IN THE NACELLE MIRROR. APCH WAS NORMAL WITH PROPER AIRSPD. THERE WAS NO INDICATION OF PROBS AS I REDUCED THE THROTTLE PRIOR TO T/D. I TOUCHED THE MAINS FIRST AND LOWERED THE NOSE. THE NOSE GEAR COLLAPSED (NEVER ACCEPTING THE ACFT'S WEIGHT). AS THE NOSE DROPPED, THE PROPS STRUCK. I WENT THROUGH EMER PROCS; SHUTTING DOWN THE ENGS USING THE MIXTURE AND FUEL LINES. I ALSO SHUT DOWN THE FUEL PUMP AND ELECTRICAL MASTER. AFTER CLRING THE ACFT FROM THE RWY I CONTACTED OUR DIRECTOR OF OPS (PER OPS MANUAL), AND MET WITH GADO OFFICERS. ONE WK PRIOR TO THIS INCIDENT THE NOSE STRUT ACTUATOR WAS REMOVED, REBUILT AND REINSTALLED. THE ACFT HAD FLOWN ONCE PRIOR TO THIS INCIDENT W/O PROBS. I DON'T KNOW WHAT MORE I COULD HAVE DONE BUT I HAVE CONSULTED MORE EXPERIENCED AIRMEN.
