NTSB description

On August 8, 2009, about 0741 eastern daylight time, an experimental amateur-built T-Bird II, N90458, was substantially damaged during a forced landing near Keymar, Maryland, shortly after takeoff. Visual meteorological conditions prevailed, and no flight plan was filed for the local personal flight which departed Keymar Airpark (MD42), Keymar, Maryland a few minutes prior to the accident. The certificated private pilot and passenger were fatally injured. The personal flight was conducted under 14 Code of Federal Regulations Part 91.

Several witnesses reported to the Federal Aviation Administration (FAA) inspector on-scene that they observed the flight departing and then the engine "stopped." An on-scene examination of the airplane by the FAA revealed that the wooden propeller had little damage to it and was devoid of chordwise scratches to indicate any rotation prior to the accident. The aileron and elevator control cables exhibited corrosion. Fuel was found throughout the fuel system, however contaminants were also present. The engine and fuel filter were retained for further examination.

An acquaintance of the pilot reported to the Safety Board that the pilot had left a voice message on July 10, 2009 stating that he was having problems with the jury strut and the control cables. According to the FAA during a review of the logbooks; an entry dated November 13, 2007 showed that the aircraft was in compliance with all current regulations. On June 28, 2008 an entry was made showing the airplane had accomplished at least 5 hours of total flight time, which was required for the phase I flight testing. An entry on July 1, 2009 was for a test flight that was flown with 160 pounds of salt, the last logged flight entry was conducted on July 8, 2009.

According to the manufacturer of the kit-plane, on July 1, 2009, the pilot had reported to them that he had aborted a takeoff and ran into a fence damaging a jury strut and that a new strut was ordered and sent at that time. Manufacturer's invoices indicate that the pilot had also been sent new cables for the aileron on January 5, 2009 and elevator cables on January 20, 2009.

The pilot 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 issued on June 3, 2003. At that time, the pilot reported a total flight time of 78 hours.

The airplane was registered to the pilot on March 31, 2004 and was issued a special operating certificate on November 13, 2007.

The recorded weather observation at Fredrick Municipal Airport (FDK), Fredrick, Maryland, at 0748, included calm wind; visibility 10 miles, scattered clouds at 7,000 feet above ground level, temperature 19 degrees C, dew point 17 degrees C; altimeter 30.26 inches of mercury.
