Analysis

The airstrip was plowed to 2/3 of its width for its entire 1000 foot length. The pilot stated that a pickup truck was parked on the FAR end of the runway, on the runway. He reported the braking action as nil and was unable to stop prior to reaching the pickup truck. He attempted to complete the landing roll out between the pickup truck and the snowbank. The airplane's right wing struck the pickup truck and the left horizontal stabilizer struck the snowbank. The pilot was landing uphill because the airstrip is considered to be one way in and one way out.
