A single-engine aircraft crashed in a wooded area near Tomah, Wisconsin, on Tuesday afternoon, killing all six people on board — five adults and one child. The National Transportation Safety Board (NTSB) has launched a full investigation, with a focus on the plane’s final communications with air traffic control and the performance of its onboard avionics systems. The crash occurred shortly after the pilot reported an unspecified emergency, according to preliminary information from the Federal Aviation Administration (FAA).
**Context**
The aircraft, a Piper PA-32 Cherokee Six, departed from Chicago Executive Airport in Illinois en route to Minneapolis–Saint Paul International Airport. Weather conditions at the time were partly cloudy with light winds, but no immediate severe weather alerts were in effect for the region. The plane lost contact with air traffic control around 2:45 p.m. local time, approximately 15 minutes before it was scheduled to enter the approach phase for Minneapolis. Radar data shows the aircraft deviated from its planned route, descending rapidly before disappearing from primary radar coverage near the Wisconsin River valley.
First responders from the Monroe County Sheriff’s Office and the Wisconsin Department of Transportation arrived at the crash site, located about 10 miles east of Tomah. The wreckage was scattered over a quarter-mile area, indicating a high-energy impact. The NTSB has recovered the cockpit voice recorder (CVR) and the flight data recorder (FDR), both of which are being sent to the agency’s laboratory in Washington, D.C., for analysis. The CVR is expected to capture the pilot’s conversations with air traffic control, as well as any cockpit sounds, alarms, or verbal exchanges among occupants. The FDR will provide altitude, airspeed, heading, and engine performance data.
Authorities are also examining the aircraft’s maintenance records and the pilot’s flight history. The pilot, a 58-year-old man with a commercial pilot’s license and more than 3,000 hours of logged flight time, had no prior accidents or incidents on record, according to FAA databases. The identities of the victims have not been released pending notification of next of kin.

This tragedy underscores the critical role that air traffic control communications and onboard avionics play in modern aviation safety. The investigation will likely focus on whether a mechanical failure, pilot error, or external factors such as weather or bird strikes contributed to the loss of control. The analysis of the CVR and FDR will be central to understanding the sequence of events. In particular, investigators will examine the timing and content of the pilot’s emergency call, any instructions from controllers, and whether the aircraft’s transponder continued to transmit a Mode C altitude signal after the emergency was declared.
Advances in digital voice recording and data monitoring have greatly improved the ability of investigators to reconstruct accidents. The NTSB uses specialized software to synchronize radar tracks with cockpit audio, allowing them to pinpoint the exact moment when the aircraft began its descent. Additionally, the agency will analyze the aircraft’s GPS and autopilot data to determine if the pilot had programmed a specific route or if the plane was being flown manually. The presence of a child on board raises questions about the aircraft’s seating configuration and whether all passengers were properly restrained, though that will be determined through post-crash examination.
From a technological perspective, the crash also highlights the importance of real-time data links between aircraft and ground stations. While the Piper PA-32 is not equipped with satellite-based tracking systems like ADS-B Out (which became mandatory for most aircraft in 2020), it likely had a Mode S transponder that provided basic position and altitude data to radar. The fact that the plane disappeared from primary radar suggests it may have descended below radar coverage or that the transponder failed. The NTSB will also examine whether any nearby cell towers or weather stations captured anomalous signals that could help pinpoint the exact time of impact.
