N687RD
DRLIK FALCON XC
THE PILOT/BUILDER STATED THAT HE ENCOUNTERED UNCOMMANDED AND UNCONTROLLABLE ROLL AND YAW DIVERSIONS AS THE AIRPLANE PASSED THROUGH GROUND EFFECT AFTER TAKEOFF ON ITS MAIDEN FLIGHT. THE PILOT THEN ATTEMPTED TO EXECUTE A PRECAUTIONARY LANDING ON THE RUNWAY. THE AIRPLANE SUBSEQUENTLY LANDED HARD TO THE RIGHT OF THE EDGE OF THE RUNWAY AND THE GEAR AND WINGS COLLAPSED. IN HIS ACCIDENT REPORT, THE PILOT STATED THAT THE AIRPLANE WAS A RESEARCH AND DEVELOPMENT PROTOTYPE DESIGN.
On June 8, 1993, at approximately 0920 mountain daylight time, a Drlik Falcon XC experimental homebuilt airplane, N687RD, was substantially damaged during a precautionary landing at Double Eagle II Airport near Albuquerque, New Mexico. The landing was attempted immediately after takeoff on what was to have been the maiden flight of the airplane. The private pilot was not injured. Visual meteorological conditions prevailed at the time of the test flight. The pilot/builder stated he had made several successful taxi tests prior to the first flight. He further stated that as the airplane lifted off and passed through ground effect, he encountered a loss of roll and yaw control. He stated that the maximum height attained was between 50 feet and 100 feet above the ground. The instability continued and he elected to attempt a precautionary landing on the runway. The airplane landed hard about 72 feet right of the edge of the takeoff runway and the landing gear and wings collapsed. A 4 knot, left quartering cross wind existed at the time of the accident. In his accident report, the pilot stated that the airplane was a research and development prototype design.
THE EXTRANEOUS AND UNCOMMANDED ROLL AND YAW DEVIATIONS CAUSED BY INADEQUATE AIRPLANE DESIGN WHICH PRECLUDED THE PILOT FROM TAKING CORRECTIVE ACTION AND LED TO THE ENSUING HARD LANDING.
