What happened
During an approach to land on an icy lake situated in the vicinity of Nondalton, the aircraft crashed through the frozen surface. The impact caused the plane to partially submerge in the water. While the incident resulted in two injuries among the crew, no fatalities were reported. The aircraft sustained damage that rendered it a total loss.
Findings
Investigations into the accident highlighted that the flight crew failed to contact the Flight Service Station (FSS) prior to their arrival. Although the FSS had issued specific information regarding the hazardous ice conditions in the area, the pilots did not receive or acknowledge this warning before attempting the landing. The primary factor contributing to the accident was improper flight planning and decision-making by the crew regarding the surface conditions of the lake.
