Aircraft Accident/Incident Report
Redmond, Oregon 97756
Friday, May 14, 2010 7:18 PDT
NTSB Narrative Summary Released at Completion of Accident
A witness who was located in a vehicle adjacent to the accident site reported that while conducting a routine daily runway inspection, he observed the airplane in a near vertical attitude above the departure end of the active runway. The witness estimated that the airplane was about 100 to 200 feet above the ground when it performed a 360-degree roll and stalled. It then entered a nose-low attitude, made another 360-degree roll, and descended below a tree line. Another witness reported that he observed the airplane depart the active runway and initiate a normal climb. As the airplane reached the departure end of the runway it entered an abrupt climb at an approximate 90-degree angle. The witness further stated that the airplane climbed for approximately 200 feet, nosed over, and descended into the ground. A postaccident examination of the engine and airframe revealed no pre impact mechanical malfunctions. Toxicology tests of post-mortem samples from the pilot detected Amlodipine, a prescription medication used for the treatment of high blood pressure. The medication typically does not have any adverse effects, and is routinely approved by the Federal Aviation Administration.
NTSB Probable Cause Narrative
The pilot's failure to maintain airspeed, which resulted in a stall and collision with terrain.
