Analysis

The newly certificated private pilot was scheduled for an extended cross-country flight to gain experience. A newly certificated private pilot friend accompanied him. They were scheduled in a type aircraft they had not previously flown, except for a local check out. The flight was planned and approved into an area of mountainous terrain and neither pilot had mountain training or experience. While maneuvering at an altitude 700 feet below the service ceiling of the aircraft, the airplane struck a tree and then impacted into terrain.
