Narrative:

I landed my airplane nose gear up. Earlier in the week I had problems with a severe nose gear shimmy. I took into a repair facility and had it repaired. I took it out for a high speed taxi, no shimmy. I then took the airplane around the pattern for several lndgs. During the second touch-and-go (soft field) during the round out I heard the gear horn and the stall horn. Somehow I totally disregarded the horns and did not attempt to take the airplane around. The speed was too slow for me to keep the nose up and apply power. I still didn't trust the cure for the shimmy that's why I was doing soft field (slow speed) lndgs. I had an idea that there was something wrong that last approach, the gear handle did not go to the neutral position and I did not have a green light. This has happened to one of my partners before (broken wire) -- gear was down but the gear doors were open. In my situation looking back I should have contacted tower to confirm the gear down -- I didn't. Talking to tower after the incident, the individual said they thought my gear was down. At this time I don't know why the gear failed. When the aircraft nose was raised, the emergency gear extension worked lowering the nose gear. It was late in the afternoon when this happened and I was somewhat tired from working that day. I was a little stressed from the day's activities and flying the airplane seemed to relax me. The air was smooth and I liked my first soft field landing. I feel I used poor judgement on that last landing. I have a lot of time in retractable aircraft (about 3000 hours) but only about 100 hours in a single pilot aircraft. I guess I was waiting for someone to tell me what to do. One of the things I could correct is I have a habit of using small aircraft manufacturer in my call sign if I had used small aircraft model X, tower would have been alerted to my retractable gear aircraft. At the end of the runway at riverside in 'wheels' in big bold lettering, I did do a 'gumps' check but disregard the green light being on as I did visually check the mains. I feel this incident may have been prevented (pending findings on the nose gear) if I would have asked tower to confirm gear and if I had taken the aircraft around.

Title: NOSE GEAR DID NOT EXTEND ON TOUCH AND GO LNDGS AFTER REPAIR.

Narrative: I LANDED MY AIRPLANE NOSE GEAR UP. EARLIER IN THE WK I HAD PROBLEMS WITH A SEVERE NOSE GEAR SHIMMY. I TOOK INTO A REPAIR FACILITY AND HAD IT REPAIRED. I TOOK IT OUT FOR A HIGH SPD TAXI, NO SHIMMY. I THEN TOOK THE AIRPLANE AROUND THE PATTERN FOR SEVERAL LNDGS. DURING THE SECOND TOUCH-AND-GO (SOFT FIELD) DURING THE ROUND OUT I HEARD THE GEAR HORN AND THE STALL HORN. SOMEHOW I TOTALLY DISREGARDED THE HORNS AND DID NOT ATTEMPT TO TAKE THE AIRPLANE AROUND. THE SPD WAS TOO SLOW FOR ME TO KEEP THE NOSE UP AND APPLY PWR. I STILL DIDN'T TRUST THE CURE FOR THE SHIMMY THAT'S WHY I WAS DOING SOFT FIELD (SLOW SPD) LNDGS. I HAD AN IDEA THAT THERE WAS SOMETHING WRONG THAT LAST APCH, THE GEAR HANDLE DID NOT GO TO THE NEUTRAL POS AND I DID NOT HAVE A GREEN LIGHT. THIS HAS HAPPENED TO ONE OF MY PARTNERS BEFORE (BROKEN WIRE) -- GEAR WAS DOWN BUT THE GEAR DOORS WERE OPEN. IN MY SITUATION LOOKING BACK I SHOULD HAVE CONTACTED TWR TO CONFIRM THE GEAR DOWN -- I DIDN'T. TALKING TO TWR AFTER THE INCIDENT, THE INDIVIDUAL SAID THEY THOUGHT MY GEAR WAS DOWN. AT THIS TIME I DON'T KNOW WHY THE GEAR FAILED. WHEN THE ACFT NOSE WAS RAISED, THE EMER GEAR EXTENSION WORKED LOWERING THE NOSE GEAR. IT WAS LATE IN THE AFTERNOON WHEN THIS HAPPENED AND I WAS SOMEWHAT TIRED FROM WORKING THAT DAY. I WAS A LITTLE STRESSED FROM THE DAY'S ACTIVITIES AND FLYING THE AIRPLANE SEEMED TO RELAX ME. THE AIR WAS SMOOTH AND I LIKED MY FIRST SOFT FIELD LNDG. I FEEL I USED POOR JUDGEMENT ON THAT LAST LNDG. I HAVE A LOT OF TIME IN RETRACTABLE ACFT (ABOUT 3000 HRS) BUT ONLY ABOUT 100 HRS IN A SINGLE PLT ACFT. I GUESS I WAS WAITING FOR SOMEONE TO TELL ME WHAT TO DO. ONE OF THE THINGS I COULD CORRECT IS I HAVE A HABIT OF USING SMA MANUFACTURER IN MY CALL SIGN IF I HAD USED SMA MODEL X, TWR WOULD HAVE BEEN ALERTED TO MY RETRACTABLE GEAR ACFT. AT THE END OF THE RWY AT RIVERSIDE IN 'WHEELS' IN BIG BOLD LETTERING, I DID DO A 'GUMPS' CHK BUT DISREGARD THE GREEN LIGHT BEING ON AS I DID VISUALLY CHK THE MAINS. I FEEL THIS INCIDENT MAY HAVE BEEN PREVENTED (PENDING FINDINGS ON THE NOSE GEAR) IF I WOULD HAVE ASKED TWR TO CONFIRM GEAR AND IF I HAD TAKEN THE ACFT AROUND.
