11 Years to date a Beech B90 was to operate an FAA Part 91 General Aviation flight from Jackson County Airport-Reynolds Field (Michigan, USA) to Yorkville Sylvania Airport (Sturtevant, Wisconsin, USA).
On board the Pratt & Whitney PT6 SER (2 off) powered aircraft, the pilot and 1 passenger.

After the necessary preparations were completed and the engines were started the aircraft lifted off from the runway at approximately 18.00 lt (local time) and set course for its destination in IMC ( Instrument Meteorological Conditions). The flight proceeded as planned and there were no issues with the aircraft during the ~45-minute flight. The weather at Syvania Airport was far from ideal;
Wind - 100º at 5 knots
Temperature - 14ºC
Dewpoint - 13ºC
Visibility - 1 mile
Clouds - Scattered at 200 ft AGL - Overcast at 1000 ft AGL
Altimeter setting - 29.89 inHg (1012 hPa)
Precipitation - Heavy Rain
As the aircraft approached the 2272-feet long asphalt runway 08R it was configured for landing according to the relevant checklists. Over the threshold, the power levers were pulled back to the stops as the aircraft floated over the runway. It bounced before settling on the runway. Reverse pitch was selected by the pilot, but not immediately available as a result of pulling the power levers to the stops over the threshold. As the wheel brakes were applied the pilot was under the impression that the aircraft accelerated as it hydroplaned on the runway. It became apparent that the remaining runway length was not sufficient to bring the aircraft to a stop and the pilot turned the aircraft left of the runway. It impacted two ditches and broke through the airport perimeter fence before it came to a stop on a highway.

Damage to the aircraft was substantial, there was no post-impact fire. Amongst other damage the following damage was recorded;
Heavy (impact) damage to the nose section
All landing gears ripped from their mountings
Structural damage to the wings and lower fuselage
The right-hand engine ripped off its mounts
Both propellors bent
Both the pilot and the passenger sustained minor injuries and evacuated the aircraft safely. The National Transportation Safety Board investigated the runway overrun. During an interview with the NTSB, the pilot stated: "That he should have recognized that braking action would be significantly reduced with the possibility of hydroplaning, that pulling the power levers to the stops before touchdown induced a lag in the realization of reverse thrust, and that he should have executed a go-around when the airplane floated before landing."
In their report (which served as source for this blog), which was published on the 30th of September 2013, they determined that the probable cause(s) of this accident to be;
"The pilot's decision to continue the landing after touching down long and on a wet runway reduced the airplane’s braking capability, which resulted in an overrun."
