Narrative:

At the end of an IFR flight from st louis, mo, to mena, ar, I landed the C185 on amphibious floats on runway 17 with the gear up. The WX was good and not a factor. I shot the NDB approach, entered left downwind on runway 17, did a normal approach with full flaps and landed on runway 17. When the plane slid to a stop just right of the centerline, I announced on unicom the airport was closed and for all traffic to go around. The plane was jacked up and the wheels were hand pumped down and locked. Taxied to parking. I feel the problem occurred because I was complacent and did not use a checklist. Contributing to the complacency was the last part of the flight was in clear, smooth flying conditions, the NDB approach was shot just for practice and when it was completed successfully I let my guard down and didn't follow procedures. This was also only my 4TH landing in this particular aircraft since purchasing it in toronto, ontario. I have over 1400 hours in cessna 180/185's, but only 8 hours in an amphibian. Damage was limited to the skid strips on the bottom of the float keels. These skid strips will be replaced.

I SHOT THE NDB APCH, ENTERED L DOWNWIND ON RWY 17, DID A NORMAL APCH WITH FULL FLAPS AND LANDED ON RWY 17.

TAXIED TO PARKING. I FEEL THE PROB OCCURRED BECAUSE I WAS COMPLACENT AND DID NOT USE A CHKLIST. CONTRIBUTING TO THE COMPLACENCY WAS THE LAST PART OF THE FLT WAS IN CLR, SMOOTH FLYING CONDITIONS, THE NDB APCH WAS SHOT JUST FOR PRACTICE AND WHEN IT WAS COMPLETED SUCCESSFULLY I LET MY GUARD DOWN AND DIDN'T FOLLOW PROCS.
