What happened
The pilot was conducting a landing operation at a private mining airstrip characterized by significant snow cover. As the aircraft touched down and began its landing roll, the main landing gear wheels penetrated the hard surface of the snow crust rather than rolling on top of it. This sudden loss of support caused the nose of the airplane to drop forward, resulting in a nosed-over position.
The impact and subsequent rest position activated the aircraft's emergency locator transmitter (ELT). Upon inspection following the incident, the pilot assessed the extent of the damage sustained during the event. The report indicated that the propeller, wingtip, and rudder had all received damage as a result of the accident.
The investigation
The primary factor in this incident was the interaction between the aircraft's landing gear and the specific surface conditions of the runway. The snow crust provided insufficient structural integrity to support the weight of the airplane during the landing roll, leading to the gear breaking through the surface.
