APRX 40 MINUTES AFTER DEPARTURE THE PLT REPORTED HE HAD ABOUT AN INCH OF ICE ON THE LEADING EDGE OF THE WINGS. TEN MINUTES LATER WHILE BEING VECTORED TO KANKAKEE AIRPORT, COMMUNICATION WAS LOST. AN OVERFLYING AIRLINER HEARD HIM TRANSMIT 'HE WAS OVER FARMLAND AND WAS PICKING A SPOT.' THE WRECKAGE WAS SPOTTED BY A PASSING MOTORIST SHORTLY THEREAFTER.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19851129058359A](https://openairdocs.org/incident/19851129058359A), Nov 29, 1985: Beech 36BEECH, Odell, IL, Destroyed, 1 fatal. Flew even though briefed of pilot reports of severe icing. Aircraft iced up, unable to hold altitude, hit in field.

From the NTSB's public API. 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. Compare the reported make and model.
