## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

LANDED WET GRASS RUNWAY. UNABLE STOP. OVERRAN END AND NOSED OVER. 172 HAD HYDROPLANED AFTER LANDING LONG AND FAST. (.4) THE PILOT STATED THAT HE USED A SLIGHTLY HIGHER FINAL APPROACH AIRSPEED TO COMPENSATE FOR ANY POSSIBLE WIND GUSTS. AFTER THE AIRCRAFT TOUCHED DOWN, A WIND GUST LIFTED THE AIRCRAFT BACK OFF THE RUNWAY SURFACE. THE AIRCRAFT SETTLED BACK TO THE RUNWAY AND THE PILOT IMMEDIATELY APPLIED BRAKES, RAISED THE FLAPS, AND HELD THE NOSE OFF THE GROUND. THE PILOT REPORTED THAT THE BRAKING ACTION OF THE AIRCRAFT WAS MINIMAL DUE TO HYDROPLANING. THE PILOT STATED THAT A GO-AROUND WAS NOT POSSIBLE DUE TO THE LENGTH OF RUNWAY REMAINING AND A TREE LINE THAT WAS PRESENT AT THE END OF THE RUNWAY. THE AIRCRAFT TRAVELED OFF THE END OF THE RUNWAY WHERE IT IMPACTED A DEEP RUT IN THE TERRAIN. THE NOSE GEAR OF THE AIRCRAFT DUG INTO THE RUT CAUSING THE AIRCRAFT TO NOSE OVER. POST ACCIDENT INSPECTION OF THE AIRPLANE REVEALED EVIDENCE OF REVERTED RUBBER ON BOTH THE LEFT AND RIGHT MAIN LANDING GEARS.
