Narrative:

The event occurred on a flight from frankfort, ky. The WX was near minimums so I requested the NDB runway 18 at IRS. I flew the approach with the intention to circle to land runway 6. In the circle I lost sight of the airport and went missed approach. I then requested the NDB 24 because the straight-in approach was 60 ft lower and the 3 KT tailwind would not significantly affect me. The approach was flown at the normal speed (around 116 mph) and I saw the airport approximately 1 mi out. A normal descent was made and full flaps were added. The touchdown was made at about 100 mph about 1000 ft from the threshold. I applied brakes but it was like sliding on a sheet of ice. I began to pump the brakes and held the yoke full aft. But the aircraft showed no reaction. The aircraft hydroplaned off the end of the runway and just before stopping, the nose gear collapsed.
