MOONEY M20K PLT FORGOT TO PUT THE GEAR DOWN DUE TO TFC WATCH AND STEEP APCH OVER TREES NEAR THE END OF THE RWY. THE ACFT RECEIVED DAMAGE TO THE PROP AND BOTTOM SKIN OF THE FUSELAGE.

Narrative

THOUGH I THOUGHT I HAD HAD ENOUGH REST; IN RETROSPECT; THE RECENT ARRIVAL OF A BABY HAD ADVERSELY AFFECTED ME. I FORGOT TO PUT THE LNDG GEAR DOWN. IT WAS AN UNFAMILIAR ARPT; RELATIVELY SHORT. THERE WERE TREES UP TO THE END OF THE RWY; SO I USED A RELATIVELY STEEP APCH WITH THE HELP OF SPD BRAKES; WHICH WAS NOT MY USUAL ROUTINE. I MISSED THE GEAR DOWN STEP OF MY CHKLIST/GUMP CHK. I THINK THE SPD BRAKES DISGUISED THE LACK OF GEAR DOWN THOUGH I FAILED TO NOTE THE SIGNIFICANCE THAT I REQUIRED A LOWER THAN USUAL RPM SETTING TO GET MY DESIRED DSCNT RATE. THE DIFFERENCE WOULD HAVE BEEN MORE MARKED IF I HAD NOT EXTENDED THE SPD BRAKES. EVERYTHING ELSE ABOUT THE LNDG WAS PERFECT. I PUT IT DOWN JUST PAST THE NUMBERS AFTER A NICE APCH AND FLARE; BUT THE PROP STOPPED AFTER ABOUT 2 BLADES AND THEN ALL I COULD DO WAS RIDE IT IN. THERE WAS NO DAMAGE TO ANY CTL SURFACE AND I SLID TO A STOP APPROX 130 YARDS DOWN THE RWY. THE 2 MAIN FACTORS LEADING TO THIS INCIDENT WERE PROBABLY FATIGUE AND AN OUT OF THE ORDINARY APCH TO LNDG WITH DISTRACTIONS SUCH AS AN UNFAMILIAR ARPT; NUMEROUS OBSTRUCTIONS NEAR THE ARPT; TREES UP TO THE END OF THE RWY AND ALSO OTHER TFC IN THE PATTERN AND DEPARTING THE ARPT DURING MY APCH. ADDITIONALLY THE USE OF THE SPD BRAKES SOMEWHAT DISGUISED THE USUAL FEEL OF EXTENDED GEAR IN THE MOONEY. THE GEAR EXTENSION HAS VERY LITTLE EFFECT ON PITCH AND ASIDE FROM THE INDICTORS; DSCNT RATE/PWR SETTING AND SPD AND AIR NOISE AND THE INDICATORS TO NOTE GEAR DOWN AND ALL OF THESE ARE ALSO AFFECTED BY THE SPD BRAKES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED THAT HE WAS NOT ONLY DISTRACTED BY THE TREES NEAR THE END OF THE RWY; BUT ALSO HIS BABY PAX. HE HAS 10 YRS OF EXPERIENCE IN THE MOONEY AND MORE IN OTHER RETRACTABLE GEAR ACFT; BUT THIS WAS THE FIRST MISTAKE HE HAS MADE IN NOT PUTTING THE GEAR DOWN.
