What happened
While attempting a precautionary landing at the airport, an aircraft experienced difficulties related to a reported issue with fuel transfer. During the approach, observers noted irregularities in engine performance. As the aircraft neared the ground, it experienced a roll and struck the surface in a nose-first orientation.
Following the impact, a fire broke out, which was primarily concentrated around the right wing of the aircraft.
Findings
Investigations into the mechanical state of the aircraft focused on the propulsion and control systems. Inspections of the propellers, engines, and the flight control system showed no evidence of prior malfunctions or anomalies.
Regarding the fuel system, the left fuel pumps and the left fuel selector were tested and found to be fully functional. However, the condition of the right fuel pumps and the right fuel selector could not be verified because the fire damage sustained during the accident prevented testing of these specific components.
