Accident Details
The aircraft, identified as N7134J, was observed on radar flying southerly over Lake Michigan at 3,000 feet MSL. After canceling its IFR flight plan shortly after departure, no further communication with air traffic control occurred. The flight path subsequently showed an approximately 90-degree right turn towards the west, accompanied by a descent from 3,100 feet MSL to 1,900 feet MSL within 14 seconds. Radar contact with the aircraft was lost at that point.
To date, the entire wreckage of N7134J has never been located in Lake Michigan.
Weather Conditions
Weather in the area at the time included an overcast ceiling at 25,000 feet, visibility of 3 miles in mist, temperature -1 degrees Celsius, and dew point -2 degrees Celsius. An AIRMET was in effect for icing and severe turbulence in the area.
Post-accident Findings
Autopsies conducted on both pilots revealed massive injuries to the head, trunk, and extremities. These injuries suggest a high-energy impact.
No probable cause for the accident has been officially determined.
