Departed ZZZ1 VFR; climbed to 4500 ft MSL. Contacted approach and set up flight following. When handed off; I checked ATIS at ZZZ2. When 15 NM from ZZZ2; asked approach for local IFR clearance to descend through scattered clouds at 3000 ft MSL. Once ZZZ2 was in sight; was cleared for visual approach and over to ZZZ2 tower. ZZZ2 cleared to land visual runway 32. Ran mental checklist (local control gump). At the same time; tower noted other traffic in pattern. I set up a short approach to stay clear of unseen traffic doing a '360 degree turn.' all system seemed fine. No warning buzzers; no warning lights -- until the sound of metal. I had landed 'gear up!' thoughts: though I had thought I had placed the gear down; tower's calls about other traffic made me skip lowering gear; though I did set propeller; mixture; fuel pump on; etc. Short approach caused me to skip final 3 green check. And finally automatic gear drop and warning lights/buzzer did not function. What I have learned: I know some may say better use of checklist would have resolved this problem. But the bottom line is; I am good about checklists -- both written and verbal queues. There was something about this approach that interrupted my process at a key moment. Yes; I need to create a 'fail safe' double/triple checklist process; and it is hard to imagine a more life changing event than a gear-up landing. But where I really failed was not periodically checking the gear down warning and fail safe system in the plane. The plane was just out of an annual; but I did not do an in-flight system check. This is the new area/process I will add. A working warning system would have 'saved' me when all other best intentions failed.

Title: A PA28 PLT LANDED GEAR UP FOLLOWING A SHORT APCH FOR TFC AND AN INOP GEAR WARNING HORN. MENTAL VERSUS PAPER CHKLIST USED.
Narrative: DEPARTED ZZZ1 VFR; CLBED TO 4500 FT MSL. CONTACTED APCH AND SET UP FLT FOLLOWING. WHEN HANDED OFF; I CHKED ATIS AT ZZZ2. WHEN 15 NM FROM ZZZ2; ASKED APCH FOR LCL IFR CLRNC TO DSND THROUGH SCATTERED CLOUDS AT 3000 FT MSL. ONCE ZZZ2 WAS IN SIGHT; WAS CLRED FOR VISUAL APCH AND OVER TO ZZZ2 TWR. ZZZ2 CLRED TO LAND VISUAL RWY 32. RAN MENTAL CHKLIST (LC GUMP). AT THE SAME TIME; TWR NOTED OTHER TFC IN PATTERN. I SET UP A SHORT APCH TO STAY CLR OF UNSEEN TFC DOING A '360 DEG TURN.' ALL SYS SEEMED FINE. NO WARNING BUZZERS; NO WARNING LIGHTS -- UNTIL THE SOUND OF METAL. I HAD LANDED 'GEAR UP!' THOUGHTS: THOUGH I HAD THOUGHT I HAD PLACED THE GEAR DOWN; TWR'S CALLS ABOUT OTHER TFC MADE ME SKIP LOWERING GEAR; THOUGH I DID SET PROP; MIXTURE; FUEL PUMP ON; ETC. SHORT APCH CAUSED ME TO SKIP FINAL 3 GREEN CHK. AND FINALLY AUTO GEAR DROP AND WARNING LIGHTS/BUZZER DID NOT FUNCTION. WHAT I HAVE LEARNED: I KNOW SOME MAY SAY BETTER USE OF CHKLIST WOULD HAVE RESOLVED THIS PROB. BUT THE BOTTOM LINE IS; I AM GOOD ABOUT CHKLISTS -- BOTH WRITTEN AND VERBAL QUEUES. THERE WAS SOMETHING ABOUT THIS APCH THAT INTERRUPTED MY PROCESS AT A KEY MOMENT. YES; I NEED TO CREATE A 'FAIL SAFE' DOUBLE/TRIPLE CHKLIST PROCESS; AND IT IS HARD TO IMAGINE A MORE LIFE CHANGING EVENT THAN A GEAR-UP LNDG. BUT WHERE I REALLY FAILED WAS NOT PERIODICALLY CHKING THE GEAR DOWN WARNING AND FAIL SAFE SYS IN THE PLANE. THE PLANE WAS JUST OUT OF AN ANNUAL; BUT I DID NOT DO AN INFLT SYS CHK. THIS IS THE NEW AREA/PROCESS I WILL ADD. A WORKING WARNING SYS WOULD HAVE 'SAVED' ME WHEN ALL OTHER BEST INTENTIONS FAILED.
