6 Killed in Wisconsin Piper JetPROP Crash, Including Five Adults and One Child

DELLONA, Wisconsin — A Piper PA-46-350P Malibu Mirage JetPROP DLX crashed in Sauk County, Wisconsin, on the evening of October 13, 2026, killing everyone aboard. Updated local reporting identifies six victims, including five adults and one child. The aircraft, registered N931TT, was destroyed in the accident near Park Lane in the Town of Dellona.

The crash occurred at approximately 9:31 p.m. local time in a residential area near Mirror Lake State Park, northwest of Madison. The Sauk County Sheriff’s Office confirmed multiple fatalities, while subsequent reporting indicated that none of the aircraft’s occupants survived. No injuries were reported on the ground.

Emergency Response in Sauk County

According to the Sauk County Sheriff’s Office, the dispatch center received multiple emergency calls reporting a downed aircraft near Park Lane. Deputies and emergency personnel responded to the area, where they located the wreckage and confirmed fatalities.

The accident scene was secured while investigators began documenting the wreckage, collecting evidence, and establishing the circumstances surrounding the aircraft’s final flight.

Responding agencies included the Sauk County Sheriff’s Office, Lake Delton Police Department, Delton Fire Department, Dells/Delton Emergency Medical Services, the Sauk County Coroner’s Office, and the Wisconsin State Patrol.

The crash occurred near homes, raising immediate concerns about possible casualties on the ground. Authorities reported no ground injuries, and initial accounts indicated that nearby residences were not damaged.

Aircraft Identification and Flight Information

The aircraft has been identified in the Aviation Safety Network accident record as a Piper PA-46-350P Malibu Mirage JetPROP DLX, registration N931TT, manufacturer serial number 4636441, manufactured in 2008.

The aircraft was listed as operated by Compass Pro LLC and was reportedly conducting a private flight from Kenosha Regional Airport (KENW), Wisconsin, to Menomonie Municipal Score Field (KLUM), Wisconsin.

The JetPROP DLX is a turbine-powered conversion of the Piper PA-46 airframe. Although derived from the piston-powered Malibu Mirage, the JetPROP incorporates a turboprop engine and associated modifications, making accurate aircraft identification important when assessing performance and operating characteristics.

The reported flight route and aircraft identification remain subject to confirmation through official investigative records.

Thunderstorms Reported Along the Flight

Preliminary information published by the Aviation Safety Network indicates that the aircraft entered an area of thunderstorms during cruise before crashing near Dellona.

Weather observations from the vicinity included thunderstorm activity, with reports from the Wisconsin Dells area indicating cumulonimbus clouds and thunderstorms in the region. Such conditions can be associated with turbulence, wind shear, heavy precipitation, lightning, and rapidly changing visibility.

However, the presence of thunderstorms does not establish that weather caused the accident. Investigators must determine the aircraft’s actual flight path, altitude, weather exposure, pilot decisions, and mechanical condition before reaching conclusions.

Weather radar data, air traffic control communications, flight tracking information, and any available onboard records may help investigators reconstruct the sequence of events.

Federal Investigation Underway

The National Transportation Safety Board (NTSB) and Federal Aviation Administration (FAA) have been notified of the accident. The NTSB is responsible for determining the probable cause of civil aviation accidents in the United States.

Investigators will examine the wreckage, aircraft maintenance history, pilot qualifications, meteorological conditions, and operational circumstances. The extent of the investigation will depend on the evidence recovered.

At this stage, no official probable cause has been established. Any suggestion that thunderstorms, structural failure, pilot error, or another factor definitively caused the crash would be premature.

Fatalities and Developing Information

Local reporting on October 14 identified six fatalities, described as five adults and one child. Earlier reports from the Sauk County Sheriff’s Office confirmed multiple deaths but did not immediately specify the number of occupants.

Authorities have not released the victims’ identities in the initial reports reviewed. Notification of relatives and formal identification procedures may precede additional announcements.

The Aviation Safety Network initially listed the accident as preliminary, noting that its information was derived from news and other unofficial sources. Its accident record may be updated as official findings become available.

ASX News will continue following the investigation and will distinguish verified findings from preliminary reports as additional information is released.
