Narrative:
My student and I were doing takeoffs and lndgs on runway 17L. 30 mins into the flight we experienced a nosewheel shimmy on takeoff. Everything was normal on takeoff and climb out. We requested a full stop landing on runway 17R at dwh. On short final an aircraft landing runway 17L reported a tire and nose gear on the runway. At this time we initiated a go around. We asked ATC about our nose gear. They reported to us that it was missing. At the time we used all appropriate checklists for the emergency. The aircraft was landed on runway 17R dwh. Minor damage occurred on the aircraft, no fire occurred or propeller strike, some skin damage was done. FAA was notified about this incident. Callback conversation with reporter revealed the following information: reporter stated that the aircraft was a beechcraft, B23 sundowner, and that the entire wheel assembly with strut had fallen off during the takeoff. Later examination of the nose gear assembly disclosed that there were signs of metal fatigue, probably caused by hard lndgs. The reporter stated that the takeoff and landing made previously to the final one was completely routine and normal. He suspected that the reported gear on the runway may be from his aircraft since he knew that he was the last one to use the runway. He believed that it could be his gear on the runway, since none was observed during his takeoff!

Title: ENTIRE NOSE GEAR AND WHEEL ASSEMBLY FELL OFF THE ACFT UPON LIFTOFF DURING A TRAINING TKOF FLT.
Narrative: MY STUDENT AND I WERE DOING TKOFS AND LNDGS ON RWY 17L. 30 MINS INTO THE FLT WE EXPERIENCED A NOSEWHEEL SHIMMY ON TKOF. EVERYTHING WAS NORMAL ON TKOF AND CLBOUT. WE REQUESTED A FULL STOP LNDG ON RWY 17R AT DWH. ON SHORT FINAL AN ACFT LNDG RWY 17L RPTED A TIRE AND NOSE GEAR ON THE RWY. AT THIS TIME WE INITIATED A GAR. WE ASKED ATC ABOUT OUR NOSE GEAR. THEY RPTED TO US THAT IT WAS MISSING. AT THE TIME WE USED ALL APPROPRIATE CHKLISTS FOR THE EMER. THE ACFT WAS LANDED ON RWY 17R DWH. MINOR DAMAGE OCCURRED ON THE ACFT, NO FIRE OCCURRED OR PROP STRIKE, SOME SKIN DAMAGE WAS DONE. FAA WAS NOTIFIED ABOUT THIS INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT THE ACFT WAS A BEECHCRAFT, B23 SUNDOWNER, AND THAT THE ENTIRE WHEEL ASSEMBLY WITH STRUT HAD FALLEN OFF DURING THE TKOF. LATER EXAMINATION OF THE NOSE GEAR ASSEMBLY DISCLOSED THAT THERE WERE SIGNS OF METAL FATIGUE, PROBABLY CAUSED BY HARD LNDGS. THE RPTR STATED THAT THE TKOF AND LNDG MADE PREVIOUSLY TO THE FINAL ONE WAS COMPLETELY ROUTINE AND NORMAL. HE SUSPECTED THAT THE RPTED GEAR ON THE RWY MAY BE FROM HIS ACFT SINCE HE KNEW THAT HE WAS THE LAST ONE TO USE THE RWY. HE BELIEVED THAT IT COULD BE HIS GEAR ON THE RWY, SINCE NONE WAS OBSERVED DURING HIS TKOF!
