After 2 touch and go lndgs on runway 10 at dvt, we changed to the south runway for a full stop landing. Gear was lowered on downwind prior to midpoint on the runway. Gear was verified down and locked on downwind, base and final (by both instrument and student). T/D was normal. On rollout landing gear warning horn sounded. Immediately after horn sounded nose settled to runway. This was the first flight on the aircraft since the annual inspection had been accomplished. Maintenance is investigating the reason for the failed nose gear. Callback conversation with reporter revealed the following: instrument was confident about aircraft in spite of age because this was first flight after annual inspection. No way possible failure or weld could have been detected with normal inspection procedures. Several ad's on gear lock problems complied with, but not really related to this incident. Trnee was licensed a&P.

Title: NOSE GEAR COLLAPSE ON ROLLOUT AFTER LNDG.
Narrative: AFTER 2 TOUCH AND GO LNDGS ON RWY 10 AT DVT, WE CHANGED TO THE S RWY FOR A FULL STOP LNDG. GEAR WAS LOWERED ON DOWNWIND PRIOR TO MIDPOINT ON THE RWY. GEAR WAS VERIFIED DOWN AND LOCKED ON DOWNWIND, BASE AND FINAL (BY BOTH INSTR AND STUDENT). T/D WAS NORMAL. ON ROLLOUT LNDG GEAR WARNING HORN SOUNDED. IMMEDIATELY AFTER HORN SOUNDED NOSE SETTLED TO RWY. THIS WAS THE FIRST FLT ON THE ACFT SINCE THE ANNUAL INSPECTION HAD BEEN ACCOMPLISHED. MAINT IS INVESTIGATING THE REASON FOR THE FAILED NOSE GEAR. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING: INSTR WAS CONFIDENT ABOUT ACFT IN SPITE OF AGE BECAUSE THIS WAS FIRST FLT AFTER ANNUAL INSPECTION. NO WAY POSSIBLE FAILURE OR WELD COULD HAVE BEEN DETECTED WITH NORMAL INSPECTION PROCS. SEVERAL AD'S ON GEAR LOCK PROBS COMPLIED WITH, BUT NOT REALLY RELATED TO THIS INCIDENT. TRNEE WAS LICENSED A&P.
