Aircraft Accident/Incident Report

Falcon, Colorado 80831
Wednesday, May 5, 2004 11:05 MDT

NTSB Narrative Summary Released at Completion of Accident

The pilot said the airplane was at maximum gross weight. Shortly after departure, he encountered clear air turbulence. At full power of 2,250 rpm and an indicated airspeed of 75 mph, the airplane would not climb. He decided to turn around and return to the airport. After turning onto the downwind leg, the airplane encountered a "rotor wave" and the left wing dropped. The pilot applied full right aileron with no effect. The airplane entered a spiral and impacted terrain. The left wing tip scraped the ground, spinning the airplane around. It became airborne again, then the right main landing gear struck a ditch. This collapsed the nose and right main landing gears. In addition, the right wing was sheared and the empennage was buckled.

NTSB Probable Cause Narrative

the pilot's failure to maintain aircraft control. A contributing factor was the clear air turbulence encounter.
