ACFT EQUIP PROB. NOSE GEAR COLLAPSED AFTER LNDG.

Narrative

WHILE CONDUCTING A MULTI ENG TRAINING FLT; THE FLT INSTRUCTOR AND I WERE FLYING THE VOR 23 APCH INTO HUF ARPT; IN. UPON XING THE FINAL APCH FIX (VOR); I; UNDER THE SUPERVISION OF THE INSTRUCTOR; PERFORMED A GUMP CHK WHICH INCLUDED: MAKING SURE THE GAS WAS ON AND THE UNDERCARRIAGE WAS DOWN AND LOCKED. I VERIFIED THAT THE LNDG GEAR WAS DOWN AND LOCKED WITH THE 3 ILLUMINATED GEAR LIGHTS; NO RED 'UNSAFE' LIGHT; AND A VISUAL VERIFICATION OF THE NOSE GEAR DOWN BY LOOKING IN THE L NACELLE MIRROR. THEN; I PUT THE MIXTURES TO FULL RICH AND THE PROPS TO FULL FORWARD IN CASE A GAR WOULD BE NECESSARY. APPROX 1 MI FROM THE RWY DURING THE DSCNT; I; UNDER THE SUPERVISION OF THE INSTRUCTOR; PERFORMED ANOTHER GUMP CHK. AGAIN; VERIFYING THAT THE LNDG GEAR WAS DOWN AND LOCKED BY THE INDICATIONS OF 3 ILLUMINATED GEAR LIGHTS; NO RED 'UNSAFE' LIGHT; AND VISUALLY VERIFYING THE NOSE GEAR WAS DOWN BY LOOKING IN THE L NACELLE MIRROR. UPON COMPLETING THE APCH AND THE SUGGESTION ON THE INSTRUCTOR; I MANEUVERED THE ACFT FOR A HIGHER THAN NORMAL APCH TO SIMULATE A SHORT FIELD LNDG. I ALREADY HAD 2 NOTCHES OF FLAPS AND PUT IN THE THIRD NOTCH AND SLOWED TO THE SHORT FIELD APCH SPD. WITHIN 1000 FT OF THE RWY THRESHOLD; I VERIFIED; UNDER SUPERVISION OF THE INSTRUCTOR; THAT THE LNDG GEAR WAS DOWN AND LOCKED BY THE INDICATIONS OF 3 ILLUMINATED GEAR LIGHTS; NO RED 'UNSAFE' LIGHT; AND A VISUAL VERIFICATION OF THE NOSE GEAR DOWN BY LOOKING IN THE L NACELLE MIRROR. WITH THE PWR REDUCED FOR LNDG; THERE WAS NO SOUNDING OF THE LNDG GEAR WARNING HORN. ANOTHER INDICATION THAT THE LNDG GEAR WAS DOWN AND LOCKED. UPON THE LNDG ROLLOUT; THE NOSE GEAR TOUCHED DOWN AND COLLAPSED. THE ACFT'S NOSE IMMEDIATELY PITCHED DOWN AND STRUCK THE RWY SURFACE LEAVING NO TIME FOR RECOVERY. I SLOWED THE ACFT DOWN AS THE INSTRUCTOR SECURED THE ENG CTLS. WHILE THE ACFT SLOWED TO A STOP; I SHUT OFF THE FUEL; FUEL PUMPS; ENG MAGNETOS; AND THE ELECTRICAL EQUIP. THE INSTRUCTOR RADIOED THE TWR THAT WE WERE ALRIGHT AND WE DISEMBARKED THE ACFT.
