What happened
The commercial certificated pilot was operating an airplane equipped with tundra tires at a remote location adjacent to a lodge. The destination was a dirt surface airstrip oriented north-south, measuring approximately 1,200 feet in length and 20 feet in width.
According to the pilot's account, the aircraft was aligned for a landing toward the north end of the strip. The touchdown occurred approximately two feet short of the designated threshold. Upon contact with the ground, the right main landing gear struck a log stump that had been hidden by surrounding bushes just beyond the threshold area.
The impact force was sufficient to tear the right main landing gear completely off the airframe. Following the loss of the gear, the right wing of the aircraft struck the ground.
