Narrative:The pilot had been skiing in the Rocky Mountains (elevation 8,900 feet) for a week. He departed in his non-pressurized single-engine airplane and climbed up to 21,600 feet; he had no supplemental oxygen onboard. Approximately 1 hour 45 minutes into the flight, the airplane reached a maximum altitude of 22,100 feet before entering a rapid descent. The airplane impacted mountainous terrain in an uncontrolled spin. Examination of the airplane and engine revealed no evidence of any pre-impact discrepancies. The Emergency Locator Transmitter (ELT) functioned properly, and the airplane was located by the Civil Air Patrol the following day. CAUSE: the pilot's failure to maintain aircraft control as a result of incapacitation (from hypoxia) due to the in-flight decision to fly at altitudes where oxygen is required, without oxygen available.
