PILOT OF C210 FAILS TO PERFORM BEFORE LANDING CHECKLIST AND LANDS GEAR UP.

Narrative

IT WAS A COLD; CLEAR DAY WITH NO TFC IN THE PATTERN OR NEARBY THAT SHOWED UP EITHER VISUALLY OR ON MY GARMIN TFC AVOIDANCE SYSTEM. I WAS RETURNING FROM A SHORT TRIP WITH 2 PAX. I ENTERED A L DOWNWIND FOR RWY X AT ZZZ. I THEN PROCEEDED TO GO THROUGH MY LNDG GUMP RITUAL. I PULLED BACK ON THE THROTTLE; PUT MY PROP FULL FORWARD; AND MIXTURE RICH; AND GAVE IT A NOTCH OF FLAPS. SOMEHOW; I MISSED THE UNDERCARRIAGE WHICH IS DIRECTLY TO THE L OF ALL OF THE ABOVE. THERE WERE NO DISTRS; NO TFC; NO TALKING IN THE ACFT; NO REASON TO MISS IT WHATSOEVER. WHEN I CALLED BASE; I NOTICED MY SPD WAS HIGHER THAN NORMAL; SO I TRIMMED UP AND REDUCED MY THROTTLE. AS I WAS TURNING FINAL; I SAW THAT I WAS HIGHER THAN NORMAL SO I THROTTLED BACK. I HEARD A BONGING IN MY EAR BUT ASSOCIATED THAT WITH AN OM AND PROCEEDED ON TO THE RWY. I CONTINUED DOWN AND DOUBLECHKED MY MANIFOLD PRESSURE AND MIXTURE TO MAKE SURE I WAS GOOD FOR A GAR. WHY I DIDN'T DO MY NORMAL CHK OF THE GEAR IS BEYOND ME. AS I WENT DOWN THE RWY; I SEEMED TO BE IN THE AIR FLOATING A LONG TIME BLEEDING OFF AIRSPD AND I WAS WONDERING WHY I WAS NOT TOUCHING DOWN. THE SCREECHING SOUND GAVE ME THE ANSWER. THE LNDG WAS REMARKABLY SMOOTH. I SHUT OFF THE MASTER AND EVACED MYSELF AND MY PAX. WE PROCEEDED IMMEDIATELY TO THE FBO TO NOTIFY FSS THAT THERE WAS AN AIRPLANE ON THE RWY. WE THEN CALLED THE STATE POLICE TO RPT AN INCIDENT INVOLVING MY ACFT. ARRANGEMENTS WERE MADE TO REMOVE THE ACFT FROM THE RWY AND MOVED TO STORAGE. WE WILL NOTIFY THE FAA FIRST THING IN THE MORNING. NO DRUGS OR ALCOHOL WERE INVOLVED; NOT EVEN AN ASPIRIN. I VOLUNTARILY PROVIDED A URINE SAMPLE TO THE STATE POLICE TO VERIFY AS MUCH. THE CORRECTIVE ACTION WOULD HAVE BEEN TO UTILIZE A WRITTEN CHKLIST. THE ACFT WAS LIFTED IN PLACE AND THE GEAR EXTENDED WITH NO PROB. THE ACFT WAS THEN TOWED THE HALF MILE TO THE HANGAR; THUS CLEARING THE RWY. THE ACFT SUSTAINED THE LOSS OF AN ANTENNA ON THE BOTTOM OF THE PLANE; A FEW MINOR SCRATCHES; A TRASHED PROP; AND A DESTROYED ENG. UPON FURTHER REVIEW OF MY RECORDS; I DISCOVERED THAT THE ACFT WAS OUT OF ANNUAL. THE ANNUAL WAS DUE IN AUG/08. IT WAS SUPPOSED TO HAVE BEEN SCHEDULED IN JUL/08; BUT WAS PUT OFF DUE TO SCHEDULING DIFFICULTIES AT THE SHOP. FOR WHATEVER REASON; THE PLANE WAS NOT RESCHEDULED AND MANAGED TO SLIP THROUGH THE CRACKS OF EVERYONE'S MIND. MY OTHER PLANE IS DUE IN JAN/09 AND I SUPPOSE I JUST CONFUSED THE 2 DATES.
