NTSB summary
HISTORY OF FLIGHT On August 8, 2009, about 0741 eastern daylight time, an experimental amateur-built Kociemba, T-Bird II, N90458, was substantially damaged during an uncontrolled descent to the ground near Keymar, Maryland, shortly after takeoff. The certificated private pilot and passenger were fatally injured. Visual meteorological conditions prevailed, and no flight plan was filed for the local flight which departed Keymar Airpark (MD42), Keymar, Maryland, a few minutes prior to the accident. The personal flight was conducted under Title 14 Code of Federal Regulations Part 91. According to witnesses, who were outside their residence at the time of the accident, they observed the airplane after it took off from MD42. They saw it disappear behind a line of trees, and then reappear, traveling in the opposite direction. According to the Federal Aviation Administration (FAA) inspector on scene, one witness, using an airplane model, demonstrated that the aircraft banked at a high angle and then nose-dived toward the ground, with some rotation. Two other witnesses located at the departure airport did not observe the airplane in flight; however, they heard the airplane's engine. One of those witnesses described the sound as being "overloaded and struggling and maybe indicated a high angle of attack." The other witness heard the engine "suddenly stop," followed by a "loud bang." PERSONNEL INFORMATION The pilot, age 61, held a private pilot certificate issued July 25, 2003, with a rating for airplane single-engine land. His most recent FAA third-class medical certificate was issue
Probable cause
The pilot's failure to maintain adequate airspeed following a total loss of engine power due to fuel contamination.
