Narrative:
A Honda HA-420 HondaJet landed and hydroplaned off the end of runway 24 at Summerville Airport, SC (KDYB), striking a berm.
The aircraft caught fire and was completely destroyed as a result.
The pilot stated that he delayed their departure from Wilkesboro Airport to let rainstorms pass through the Summerville area. He knew that as a result of the weather, he would be landing on a wet runway.

The pilot said that he flew the RNAV (GPS) RWY 24 instrument approach into DYB. The pilot coupled to the autopilot for the approach until about 600 ft msl when he took manual control of the airplane. The wind was calm. The pilot said he flew the approach at a Vref of 120 knots with full flaps and immediately applied full brake pressure upon touchdown. He said, "...the brakes immediately began to pulsate in anti-skid mode and because of that, very little braking effort was being done to slow the plane despite full pedal pressure." He described the response of the anti-skid system as having a slower on/off cycle, than he had experienced on previous wet runway landings, where the system had a more rapid on/off response. The pilot said that it became apparent about halfway down the runway that he would not make the turn off at the second taxiway. He added that he was not concerned because there was plenty of remaining runway and "...this plane has always stopped with reserve length remaining even when this runway is wet."
The pilot added that he considered a go-around, but the left brake "grabbed", and the airplane’s nose suddenly yawed to left. This began a sequence of left and right skids. The pilot said he used the rudder pedals to keep the airplane on the runway and was able to straighten the nose out right before they went off the runway into the grass. The airplane slid down a series of embankments before coming to a stop. The airplane caught on fire, but all six occupants were able to safely exit through the main cabin door.
