Flight Planning and Navigation
The pilot reported departing and planning to follow Interstate 70 toward his destination. He intended to cruise at 10,500 feet, or "until higher was necessary." Navigation was conducted using a World Aeronautical Chart, a visual flight rules chart with a scale of 1:1,000,000.
In-Flight Situation
After approximately 30 minutes of flight, the pilot became aware of the narrowing valley and the significant rising ground elevation. When the Eisenhower Tunnel, located at an elevation of 11,000 feet, became visible, he realized that more altitude was required. However, with full throttle, only minimal positive climb could be achieved.
Decision and Maneuver
The pilot considered executing a 180-degree turn but was concerned about stalling in such a tight turn. He decided to try climbing through a cleared ski run just left of Interstate 70. Subsequently, the airplane impacted rising terrain at 11,500 feet. The density altitude at that location was 14,992 feet.
Aircraft Damage
The impact resulted in damage to both wings, including rib and spar damage. The cabin overhead was bent, and the engine firewall exhibited crushing.
Aircraft Performance Data
The airplane's Pilot's Operating Handbook (POH) specifies that its service ceiling is 14,000 feet.
