N6074APiper Aircraft PA 46-350P · 2008

The pilot reported that he was landing from an autopilot-coupled GPS approach when he noted that his airspeed over the runway numbers was 115 knots. The airplane floated over the wet runway touching down “just past the numbers”. The pilot applied full braking with over half of the runway remaining. The airplane slowed, but still slid off the end of the runway into the dirt. The airplane ground-looped, collapsing the left main landing gear and coming to a stop 180o facing the runway. The airplane sustained substantial damage to the left wing. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The recommended approach speed for the airplane is 85 knots.
