The airplane struck two ditches before coming to rest on a road. 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 realization of reverse thrust, and that he should have executed a go-around when the airplane floated before landing. No mechanical failures or malfunctions of the airplane were reported. Heavy rain was reported about the time of the accident at a nearby airport. ## Factual narrative On October 22, 2012, about 1845 central daylight time, a Beech B90 airplane, N821DA, collided with a fence and a ditch when it overran runway 8R (2,272 feet by 38 feet, asphalt) while landing at the Sylvania Airport (C89), Sturtevant, Wisconsin. The commercial pilot was not injured and his passenger received minor injuries. The airplane sustained damage to its fuselage and both wings. The airplane was registered to Direct Action Aviation LLC, and was operated by Skydive Midwest. The accident flight was conducted under the provisions of 14 Code of Federal Regulations Part 91 as a personal flight. Instrument meteorological conditions prevailed for the flight, which was not operated on a flight plan. The flight originated from the Jackson County Airport-Reynolds Field (JXN), Jackson, Michigan, about 1800. The pilot reported that the landing approach was normal and when the airplane crossed the runway threshold it floated and he pulled the engine power levers to the stops. He stated that although he did not remember the airplane bouncing, his passenger told him that it had. He pulled the power levers to reverse, but there was no immediate reverse thrust. He applied brakes and felt the airplane accelerate. He recognized that he would not be able to stop the airplane on the remaining runway and attempted to steer it to the north. The airplane left the runway, impacted two ditches and came to rest on a highway. 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 realization of reverse thrust, and that he should have executed a go-around when the airplane floated before landing. The pilot reported no mechanical failures or malfunctions of the airplane. At 1853, weather conditions reported at the Kenosha regional Airport (ENW), located 6 miles south of the accident site, included heavy rain. ## Aircraft - Registration: [N821DA](https://openairdocs.org/deregistered/N821DA-2024-04-30), registration cancelled 2024-04-30, S/N LJ-406, built 1968 (OpenAirDocs) - Reported make and model: BEECH B90 - Registry model: [Beech B90](https://openairdocs.org/model/beech-b90) (registry code 1152912) (OpenAirDocs) - Registry engine: [U/A Canada PT6 SER 578HP](https://openairdocs.org/engine/u-a-canada-pt6-ser-578hp) (registry code 61501, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: LJ-406 - Airframe hours: 12637 - Engines: Pratt & Whitney PT6 SER 578HP 550 horsepower turbo prop; Pratt & Whitney PT6 SER 578HP 550 horsepower turbo prop - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Skydive Midwest - Registered owner: Direct Action Aviation LLC - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, September 21, 2012 - Departed: JXN, Jackson, MI - Destination: C89, Sturtevant, WI - Airport: C89, Sylvania Airport, runway 08R, 2,272 × 38 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
