What happened
The pilot departed Richfield Municipal Airport in central Utah on a personal flight destined for Prescott, Arizona. The primary objective of the trip was to reach his mother, who was critically ill. At the time of departure, conditions were deteriorating, with windy weather, low ceilings, and approaching dusk limiting visibility.
The aircraft had been loaded with 284 pounds of cargo. During flight, the load shifted due to inadequate restraint. The unsecured freight moved aft and became wedged against the backseat controls. This mechanical interference prevented the pilot from manipulating the flight surfaces. Consequently, the aircraft flew in a heading opposite to its intended direction of travel before impacting terrain.
The investigation
Investigators examined the wreckage site and the condition of the cargo bay. They discovered that the freight had not been properly secured prior to takeoff. Upon impact, the cargo mass had migrated toward the rear of the cabin. It jammed against the control mechanisms located behind the pilot's seat, rendering them inoperative.
Findings
The primary factor leading to the accident was the failure to secure the payload. The weight and position of the 284 lbs of cargo caused a critical shift in the center of gravity and blocked essential flight controls. This mechanical blockage resulted in an uncontrollable descent. The pilot was unable to recover the aircraft due to the physical obstruction of the control column or pedals.
Safety message
Proper cargo restraint is mandatory for all flights. Unsecured freight can shift during turbulence, acceleration, or banking maneuvers, potentially jamming flight controls or altering the center of gravity beyond safe limits. All cargo must be tied down using appropriate straps or nets to prevent movement in any direction.
