A twin-engine airplane crashed into a wooded area short of the runway during a night approach to Grand Rapids-Itasca County.

What happened

During a nighttime approach to Grand Rapids-Itasca County, a twin engine airplane struck treetops and subsequently burst into flames. The impact occurred in a forested region situated approximately 1 to 1.5 miles before the runway threshold. During the final approach phase, the aircraft descended beneath the established minimum descent altitude. The accident resulted in one fatality and left the pilot with serious injuries.

Findings

Investigations into the crash identified several environmental and operational factors. At the time of the accident, visibility was significantly reduced due to fog and a low cloud ceiling, resulting in weather conditions that were below established minimums. The primary factor contributing to the accident was the pilot's failure to adhere to approved procedures during instrument flight rules (IFR) operations, specifically by descending below the minimum descent altitude.

Probable cause

The pilot conducted improper IFR operations by descending below the minimum descent altitude during approach.
