What happened
On the date of the accident, the pilot began the day by flying from a home airport to a second location to collect employees from a marketing firm for an out-of-state business trip. Shortly before the return leg of the flight commenced, a fourth passenger joined the group due to a cancelled commercial flight. During the takeoff phase of this return journey, which occurred at 2003, the aircraft was operating under IFR flight rules.
During the initial stages of the flight, the pilot experienced difficulties with navigation. After receiving an IFR clearance, the pilot misread the instructions back to air traffic control, though a correction was provided. Radar tracking indicated that the aircraft initially followed the assigned south-southwest heading but then drifted into a right turn toward the west. Although the controller intervened with a heading instruction to intercept a VOR, the aircraft subsequently performed another right turn back toward a westerly direction while continuing to climb.
As the flight progressed, the aircraft entered a left turn and transitioned into a rapid, spiraling descent. At the time of this maneuver, the aircraft was flying in instrument meteorological conditions. The aircraft type impacted the ground in an open cornfield, resulting in fatalities and injuries to those on board.
Findings
Investigations into the accident revealed several critical factors. Post-accident examinations of the engines and the airframe showed no evidence of mechanical failure or pre-existing malfunctions. However, weight and balance assessments determined that the aircraft was operating at least 383 pounds over its maximum gross weight. Additionally, observations from personnel at the fixed base operator suggested the pilot appeared fatigued prior to departure.
