Narrative:

Departed hot to make several touch and go lndgs in final preparation for CFI rating. Flight instrument occupied left seat. Throw over yoke in small aircraft was on right side. Climbed to pattern altitude, entered downwind leg for short field, crosswind, spot landing on runway 5. On downwind leg at point where normally do prelndg checklist instrument asked question. We continued to discuss various aspects of procedure to T/D. Prelndg check never entered my mind again until T/D. Damaged flaps, belly skin from nose gear doors approximately 3 1/2' back and bent back both propeller ends. Throttle was closed, engine idling and airspeed just at stall speed at T/D. Airplane slid straight 400'. Causes: I was relaxed with high time competent instrument in left seat. Instrument was relaxed with me with over 500 hours in the airplane. The gear warning horn either did not sound or couldn't be heard with headsets and intercom. Perhaps should be wired through radio. The throw over control arm blocks gear switch and lights. Primary cause: distraction of conversation, albeit necessary for instruction.
