PA34 PLT HAD THE NOSE GEAR COLLAPSE AFTER LNDG.

Narrative

AS I TURNED FROM L BASE TO FINAL AT PSM; I SAW THAT I WAS SET UP ON VASI GS WITH 2 WHITE; 2 RED. I DID MY GUMP CHK AND PROCEEDED WITH MY DSCNT. AT THIS POINT; I HAD 2 NOTCHES OF FLAPS WITH AN IAS OF 100-105 KIAS. ON SHORT FINAL; I ADDED THE LAST NOTCH OF FLAPS. I REDUCED PWR; WENT TO RICH MIXTURE AND FULL [LOW PITCH] PROPS AND AT THE APPROPRIATE TIME; I FLARED. I RAISED THE NOSE TO ANTICIPATE A MAIN GEAR TOUCHDOWN; THEN NOSEWHEEL LNDG. AFTER LNDG; I BROUGHT THE PWR COMPLETELY BACK AND MY FRIEND (PAX) COMMENTED ON MY GOOD LNDG CONSIDERING I HADN'T FLOWN IN A WHILE. WE ROLLED DOWN THE RWY APPROX 200-300 FT AND THEN I APPLIED A VERY LIGHT BRAKE TO SLOW THE PLANE DOWN TO EXIT THE RWY ON TXWY B. AS I APPLIED THE BRAKE; THE NOSE DROPPED TO THE RWY INDICATING A NOSEWHEEL COLLAPSE. WE THEN SKIDDED TO THE L OF CTRLINE; APPROX 100 FT FROM THE INITIAL IMPACT WITH THE GND; BEFORE COMING TO A COMPLETE STOP. THE GEAR LIGHTS WERE STILL INDICATING GEAR SAFE -- 3 GREEN; NO RED. I SHUT EVERYTHING DOWN AND WE IMMEDIATELY EXITED THE AIRPLANE.
