What happened
The aircraft encountered an electrical failure while operating under instrument flight rules (IFR). During this phase of the flight, contact via radio and radar was lost. The pilot reported that the aircraft was intermittently entering and exiting cloud cover during the final stages of a cross-country flight. At the time of the incident, the cloud ceiling was approximately 800 feet.
The pilot successfully descended through the clouds and landed the aircraft in a soybean field. There were no reports of injuries or fatalities associated with this landing.
The investigation
An examination of the aircraft revealed that the alternator had failed. This mechanical failure is consistent with the reported electrical issues during flight.
Findings
The primary factor contributing to the event was the alternator failure. This led to the loss of electrical power, which subsequently caused the loss of radio and radar communication capabilities. The pilot's decision to descend and land in an available field prevented further complications.
