Analysis

The aircraft collided with a tree on top of a 12,000 foot mountain after it had departed Aspen, en route to denver. The aircraft should have climbed over the mountain without problems. The pilot only remembers the airspeed decaying and lowering full flaps prior to colliding with the tree. Both occupants received only minor injuries during the accident but were not rescued for three days. The passenger died from hypothermia and the pilot received serious frost bite of both feet.
