What happened
The incident occurred during cruise flight in the vicinity of Oshkosh, Wisconsin. At some point during this phase of flight, the aircraft's engine ceased operation for reasons that could not be determined from the available information. Following the loss of power, the pilot established communication with air traffic control at Wittman Regional Airport (KOSH). The pilot was subsequently cleared by air traffic personnel to proceed to the airport and land on runway 27.
Despite being cleared for approach, the pilot attempted to restart the engine in flight. These efforts proved unsuccessful, leaving the aircraft without propulsion. With no possibility of reaching the runway at Wittman Regional Airport, the pilot made the decision to ditch the aircraft into a body of water located approximately four miles east of the airport.
