Agricultural Aircraft Overweight Crash During Dusting Operations (N647U)

What happened

The aircraft was engaged in an agricultural dusting operation when it began to lose altitude rapidly as the pilot initiated a turn to commence the application process. The aircraft subsequently collided with the ground.

At the time of the incident, the aircraft was loaded to 470 pounds over its maximum gross takeoff weight limit. Weather conditions at the site included gusty winds blowing from the south. To address these conditions, the pilot's initial maneuver involved turning toward the field in a downwind direction. These environmental factors were noted as being conducive to low-level windshear.

The investigation

Investigators determined that the aircraft was substantially overweight prior to takeoff. The combination of excessive weight and adverse weather conditions played a critical role in the aircraft's inability to maintain altitude during the initial phase of the dusting run.

Findings

The accident was influenced by several key factors:

• N-number not provided
• Agricultural aircraft operation
• Excessive weight: The aircraft exceeded its maximum gross takeoff weight by 470 lbs.
• Weather conditions: Gusty winds from the south and low-level windshear were present.
• Pilot decision: The initial turn was made downwind into the gusty conditions.
