Incident Overview
During pre-departure taxi operations on a hard-packed, snow-covered runway, the pilot of a ski-equipped airplane was performing back-and-forth movements. The purpose of this maneuver was to warm the engine oil and to polish any frost that might have accumulated on the underside of the skis.
Loss of Directional Control
On the final taxi pass, the airplane began to drift to the left. The pilot applied full right rudder and a short burst of full engine power in an attempt to correct the drift. Despite these inputs, the airplane continued its leftward movement and subsequently struck trees located along the edge of the runway.
Damage Assessment
The collision with the trees resulted in substantial damage to the wings and fuselage of the airplane. The pilot reported that there were no preaccident mechanical anomalies that would have precluded normal operation.
Conclusion
The incident occurred during ground operations, with the airplane sustaining damage from impact with trees. No further details regarding the aircraft type, registration, or injuries were provided in the source.
