Narrative:The aircraft departed Dayton, Ohio on a flight to San Jose, California. While in cruise flight at Flight Level 310, 20 miles west of Denver, Colorado, the flight encountered severe clear air turbulence which caused major fluctuations in speed and oscillations in both pitch and roll. During these departures from controlled flight, the number one engine and 5.79 m (19 feet) of the leading edge of the left wing separated from the aircraft. In addition, the number four engine pylon cracked and experienced substantial structural damage. The flight conducted a precautionary descent and landed at Stapleton International Airport, Denver, Colorado. Preceding the occurrence, the flight was encountering light to occasionally moderate chop, with moderate to severe turbulence forecast.
